Brain impact with skull temporarily stops working normally No obvious signs of anatomic lesion Begins complex cascade of biomechanical dysfunction Disrupts brain delicate neuronal homeostasis o Symptoms due to metabolic & physiologic abnormalities vs. structural pathology Coup Injury o Under site of object impact o When head encounters a Decelerative (moving) or Accelerative force (Stationary) head Contrecoup o When the head is moving Coup-Contrecoup o Head goes back & forth Coup & Contrecoup can happen individually or together** DECELERATIVE FORCE: o Bike example of head hitting into brick (he’s moving & immediately stopped because brick wasn’t moving) = COUP INJURY https://youtu.be/yhQAK8_bzpg 7 Ortho Lecture Notes Combined o Football player example = catching ball into wall (he’s moving & immediately stopped because wall wasn’t moving lol) = COUP INJURY ACCELERATIVE FORCE: o Football example = player runs into other play & hits him in the head with his helmet = COUP-CONTRECOUP o Shovel Example LOOOL = dude beats the shit out of his friend with a shovel in the head = COUP-CONTRECOUP Patient Presentation o LOC only 10% o CAB *always check*** Circulation Airway Breathing o HA (most common) o Emotional disturbance Distraught Crying no reason o Dizzy, vertigo, tinnitus o Insomnia o Photophobia o Amnesia Retrograde – events preceding Anterograde – events after injury forgotten o Confusion/ change in mental status Vacant stare (befuddled expression) Delayed verbal expression Inability to focus (easily distracted) Disoriented (time, date, location…walk in wrong direction) Slurred speech (disjointed, incoherent Incoordination (stumble, gait, can’t walk straight, etc.) o Vomiting / nausea o Symptoms compounded by stress Example: https://youtu.be/rOoQar20uQE o Note: if brain injury occurred = good chance that cervical spine injured 8 Ortho Lecture Notes Combined On the field clinical examination SCAT 5 o Rule out emergent situation: CABFE circulation, airway, bleeding, fractures, etc. o Level of consciousness = AVPU A = Alert V = Responds to Voice P = Responds to Pain U = Unresponsive o Inspect the head & neck Battle’s Sign = Post auricular hematoma basilar fracture 9 Ortho Lecture Notes Combined Otorrhea = Leakage of CSF from ears Racoon eyes = Periorbital ecchymosis (bruising) from leakage of blood Hemotympanum = Blood behind Tympanic membrane o Palpate Head, Face, TMJ, Nose, Neck for tenderness/ potential fracture o Use SCAT5 if person is responsive Concussion (S06.0X0S no LOC; S06.0X9A w/LOC) Traumatic Brain Injury (S06.2X9A w/LOC; S06.300A no LOC) Definition: World Health Organization (WHO) defines mild traumatic brain injury (mTBI) as “an acute brain injury resulting from mechanical injury to head from external physical forces.” The terms “mTBI” & “concussion” have become synonymous, although technically, “concussion” represents only one type of mTBI. Epidemiology Researchers estimate that mTBI affects ~42 million worldwide each year o particularly common among teenagers & young adults. 10 Ortho Lecture Notes Combined Estimated 1.74 million persons in US have TBI each year; 75-95% are mild Annual incidence of sports-related concussion in US 1.6 to 3.8 million & likelihood of contact sport athlete experiencing a concussion is as high as 20% per season. o In football alone, 10% of US college & 20% US high school players have brain injuries/ season (Chronic traumatic encephalopathy in athletes: progressive tauopathy after repetitive head injury. Neuropathol Exp Neurol. 2009;68(7):709.) Sports-related concussion o more in girls vs. boys in similar sports o 2nd most common injury in College football & Female Soccer o HS-aged American football players have more concussions than college-aged players Etiology: Majority of injuries occur via falls & MVA mTBI present in ~25% of patients injured in MVA collision. Other subpopulations predisposed to mTBI: o contact sport athletes (football, boxing, hockey, soccer, MMA, etc) o military personnel o domestic violence victims Pathogenesis Concussion injuries = result of physical force causing mechanically-induced brain trauma w/o obvious gross anatomic lesion. Mechanical insult may provoke a complex cascade of biochemical dysfunction o Begins w/mitochondrial dysfunction; o disrupts brain’s delicate neuronal homeostasis. o Concussion & related symptoms thought to result from functional metabolic & physiologic abnormalities vs. structural pathology. Clinical Presentation: Sx start immediately, or evolve over min-hours Headache = one of most common & identifiable symptoms Fatigue or low energy Dizziness/Tinnitus/Vertigo Insomnia Photophobia Amnesia o Retrograde – events preceding the injury o Antegrade – events following the injury Confusion/Mental Status Changes o Vacant stare befuddled facial expression o Delayed verbal expression slower to answer questions or follow instructions o Inability to focus attention easily distracted & unable to follow through w/normal activities o Disorientation walking in the wrong direction, unaware of time, date, place o Slurred or incoherent speech (making disjointed or incomprehensible statements) o Gross incoordination observable (stumbling, inability to walk tandem/straight line) Emotions disproportionate to circumstances - distraught, crying for no apparent reason 11 Ortho Lecture Notes Combined Loss of consciousness – occurs in about 10% of injuries Patients often complain that symptoms are compounded by physical or emotional stress Side note: if brain injury occurred, then high possibility of cervical spine too. Clinical Evaluation on field: Rule out emergent situation; check Circulation, Airway, Bleeding, Fractures, etc Palpation of head, neck, face, nose, TMJ for tenderness indicating fracture Inspect head & neck for signs of serious injury: i. Battle's sign = post auricular hematoma (indicates basilar fracture). ii. Otorrhea = leakage of CSF from the ears. iii. Raccoon eyes = periorbital ecchymosis secondary to leakage of blood from the anterior fossa into the periorbital tissues. iv. Hemotympanum = blood behind the tympanic membrane If conscious, ask patient to move fingers & toes, assess sensation Assess Level of Consciousness Glascow Coma Scale GCS o part of the SCAT5 o used to assess LOC o Not sensitive for defining MTBI or return to play o Objective scale Scale based on score of 15 points: o Assess eye movements, motor response, verbal response o Anything < spontaneous eye opening, obeying verbal commands, participating in oriented conversation represents an abnormal level of consciousness. Anything less than perfect is “bad”, athlete NOT cleared Use for: head injury acute medical & trauma patients Lowest score = 3 (unconscious or dead) Highest = 15 Concussion/Minor = 13-15, Moderate 9-12, Severe <8, LOC/dead <3 Emergency management is indicated for athletes who demonstrate; a Glasgow coma score less than 15 progressive neurologic signs or symptoms deteriorating mental status persistent vomiting potential spinal injury suspected skull fracture 12 Ortho Lecture Notes Combined seizures coagulopathy prior neurosurgery intoxication multiple injuries.

New research suggests that measuring brain-derived neurotrophic factors (BDNF) may help in the diagnosis of concussion. o BDNF is secreted following brain injury to help “reconnect brain circuitry”. o This protein can be easily measured & shows excellent ability to define & quantify brain injury. N-acetylaspartate is a marker of neuronal metabolic wellness, & research suggests that monitoring its level through proton magnetic resonance spectroscopy may be a useful indicator of recovery.

Mortality rate approaches 100% Head Injury Patient Instructions (form for practice) The examination that you have received today has been rendered on an emergency basis. It is not intended to be a substitute for comprehensive medical attention. Should your condition worsen or any new symptoms develop, or should you not recover as expected, contact your doctor or report to the nearest hospital at once. You have suffered a head injury. Common symptoms include headache, nausea & slight dizziness. There may be some swelling & pain at the site of impact. A head injury can cause slow bleeding or other problems inside the head that may not be detected at this time. You may return home, but a relative or friend must stay with you. Have them read the following instructions & check you every 4 hours for the next day or two. Contact your doctor or report to the emergency department if any of the following occur: A stiff neck Unconsciousness or fainting Personality changes Areas of skin numbness Persistent nausea or vomiting Difficulty speaking or slurred speech Ringing or other unusual sounds in the ear Shortness of breath or difficulty breathing Dizziness, trouble walking or staggering gait Confusion, unusual drowsiness or loss of memory Bleeding or clear fluid drainage from the ears or nose Inability to wake up completely or excessive sleeping A severe headache or a headache that is worsening or persistent Pupils of unequal size (the pupil is the dark center portion of the eye) Fever (greater than 101F/38.3C by mouth) or if shaking chills begin Visual disturbances including blurring of vision, double vision or sensitivity to light Convulsions such as twitching movements of either the eyes, arms, legs or body Any other unusual or abnormal symptoms. 19 Ortho Lecture Notes Combined Home Treatment Do not take any sedatives or sleeping pills. Do not take aspirin or compounds containing aspirin. Do not take products containing ibuprofen such as Motrin, Advil or Nuprin. If needed, the use of acetaminophen (Tylenol, Panadol, Tempra or Liquiprin) is recommended. Do not drink alcoholic beverages Do not exert yourself (No school for children or work for adults) Do not eat or drink much for the next 24 hours. (Clear liquids are best if your stomach is upset). Do not lie flat. (Sleep or nap with head elevated on at least one or two pillows). Do not drive a car or operate tools which could harm you if you are not alert. I have received a copy of the above instructions. I understand that I have received an emergency evaluation only. I have been advised as to the occasionally slow insidious nature of head injuries & the possible fatal consequences, & I clearly understand that although I have been permitted to return home, that I am responsible for arranging follow-up care as instructed above.

Describe the clinical manifestations (symptoms & signs/exam findings) for the different conditions 6. Identify which diagnostic studies would be useful & the expected findings. 7. Describe the management options for the conditions. Dizziness is defined as a feeling of uncertainty about one's physical orientation in space. It is a broad term & is applied by the patient to a number of different sensory experiences - a feeling of rotation or whirling as well as non-rotary swaying, weakness, faintness, light-headedness, or unsteadiness. Blurring of vision, feelings of unreality, syncope, & even petit mal or other seizure phenomena may be called `dizzy spells’.

(CN VIII) Two other organs that are part of the Vestibular system o Somatic Receptors (proprioception) o Information from the proprioceptive organs from the muscles & joints. Neck extremely important. All three components are needed for proper balance. A problem with anyone one of these systems can lead to dizziness or balance issues. When dealing with dizzy patients one should consider an evaluation of all three systems; additionally problems with the cerebrovascular & cerebellar systems are also may need to be evaluated based on the rest of the symptomatic picture. Dizziness Categories 1) Vertigo (H81.399) - Spinning subjective & objective illusions of motion usually rotational/spinning or tilting. True vertigo is usually related to a vestibular dysfunction problem of the inner ear 24 Ortho Lecture Notes Combined o If severe it may be accompanied by nausea & vomiting. o Vertigo occurs when there is conflict between the signals sent to the brain by various balance- & position-sensing systems of the body. You feel like your moving Objective vertigo - environment moving/spinning around the person Environment moving Subjective vertigo - the patient feels as though he or she is moving/spinning/tilting/rotating within the environment. The patient may feel like they are being pulled towards the floor. Sensation may worsen with motion or even when laying down. May feel like motion sickness (car or ferris wheel) Feel like spinning within environment that is blurry around you Vertigo is often seen in the conditions like: Inner ear: BPPV, Meniere Disease, Vestibular Neuritis & Acute Labyrinthitis. Head injuries Migraines Vertebrobasilar artery insufficiency Peripheral Vertigo – due to prob of inner ear e.g. BPPV, Meniere, Labyrinthitis Unidirectional nystagmus, horizontal or rotational Usually peripheral, so if focus on a spot, spinning will stop Spinning slows w/eyes closed Positionally induced Accompanied by hearing loss Central Nystagmus lasts longer – takes longer to go away (weeks to months) Nystagmus vertical and persists w/eyes open or closed Periph Central Onset Sudden Gradual Imbalance Mild/mod Severe Nausea Frequent Infrequent CNS signs Absent Present Nystagmus Torsion/horizontal Vertical Duration Brief/sec-min Weeks/months Auditory symptoms Common Rare 2) Presyncope (Near-Faint Dizziness) (R55) Sudden feeling of impending loss of consciousness. FROM diminished amount of oxygen to the brain. o Cardiac mechanisms, atherosclerosis o Due to exercise (high CO2 causing acidity, drugs, acidity of blood) The patient may describe the following associated symptoms: o Pallor, diaphoresis/sweating, a roaring sensation in their ears, sighing respirations (to increase O2), restlessness, abdominal distress, yawning, weakness and/or dimming or blurred vision. Often caused by medications o Othostatic hypotension 25 Ortho Lecture Notes Combined o Vasovagal syncope o Cardiac disease 3) Syncope (fainting) a transient loss of consciousness accompanied by the loss of postural tone that is due to inadequate blood flow to the brain (a fall in systemic arterial pressure). Recovery is usually spontaneous; no need for resuscitation. A frequent cause is acute hypotension (vasovagal response). 3) Disequilibrium (R42) Feeling of being off-balanced when standing or walking (inability to maintain an upright posture); sensation of being off balance & most often characterized by frequent falls in a specific direction This may occur due to: o cerebellar, motor, or posterior column problem. There is associated ataxia & it is considered a multi-sensory problem May be common in elderly Not associated with nausea or vomiting. It is an unsteadiness, imbalance or loss of equilibrium, Commonly seen with: o Cervicogenic dizziness o Multisensory disorder o Parkinson’s disease o Diabetic neuropathy 4) Visually-induced dizziness - an alteration in the vestibulo-ocular reflex system resulting in dizziness. Change in visual acuity such as ocular pathology or New prescription for one's glasses can cause such an alteration. E.g. adjusting to new glasses 5) Lightheadedness (giddiness) (R42) -all other vague & hard to describe sensations of uneasiness in the head. May feel like they will faint or their head is weightless. patient may have subtle dysfunction within the orientation systems or psychological problems Often attributed to emotional causes o Examples: Hyperventilation is a common cause of dizziness in anxious young people. Panic attack is another example. (Baloh, 1998) Lightheadedness is a feeling that the patient is about to faint or "pass out." Although they may feel dizzy, they do not feel as though their surroundings are moving. Lightheadedness often goes away or improves when they lie down. Lightheadedness usually is not caused by a serious problem. Often is caused by a momentary drop in blood pressure & blood flow to your head that occurs when you get up too quickly from a seated or lying position (orthostatic hypotension). Many causes, including: o allergies, illnesses such as the flu or colds, vomiting, diarrhea, fevers, & other illnesses that cause dehydration, very deep or rapid breathing (hyperventilation), anxiety & stress, the use of tobacco, alcohol, or illegal drugs. 26 Ortho Lecture Notes Combined o Many prescription & nonprescription medicines can cause lightheadedness. Knowing what medications your patients have can help diagnosis this condition. o Lightheadedness can also be the result of depression, anxiety or hyperventilation syndromes. o NOTE: More serious cause of lightheadedness is bleeding. Sometimes bleeding is not obvious (occult bleeding). Internal bleeding from major traumas or bleeding from the digestive tract can take weeks to be noticed & the first signs might be lightheadedness & fainting. Usually 1st sign of slow bleed is lightheadedness Basic Evaluation of the “Dizzy” Patient History o Ask the patient to describe the symptoms without using the word dizzy. o Have the patient differentiate vertigo from pre-syncope or near-syncope. o Determine if the patient has a sense of being pushed down or pushed to 1 side (pulsion). A peculiar sense of movement of objects viewed when the patient moves is termed oscillopsia (object appears to be oscillating). o Ascertain whether the symptoms are related to an anxiety episode; patients with agoraphobia may describe their symptoms as dizziness. o Determine if the sensation is continuous or episodic; if episodic, find out if the sensation is fleeting or prolonged. o Ascertain whether the onset & progression of symptoms were slow & insidious or acute. o Ask the patient about head trauma & other illnesses to determine the setting of the initial symptoms. Trauma resulting in damage to an ear often manifests as unilateral hearing loss, which may be the cause of episodic vertigo even years later (post-traumatic hydrops). Hearing loss can be associated w/peripheral vertigo o Determine if the episodes are associated with turning the head, lying supine, or sitting upright. o Determine if symptoms of an upper respiratory infection or flu-like illness preceded the onset of vertigo. o Inquire about associated symptoms such as hearing loss or tinnitus (ringing in the ears), aural fullness, diaphoresis, nausea, emesis, pallor, weakness, sighing, yawning, abdominal distress. o Determine if the patient has an aura or warning before the symptoms start. o If hearing loss is evident, find out if hearing fluctuates. o Determine if the patient has headaches. o Ask the patient about brainstem symptoms such as diplopia, dysarthria, facial paresthesia, or extremity numbness or weakness. o Ascertain the degree of impairment during an episode. o Inquire about medications. Many medications can cause dizziness; most common culprit = antihypertensive agents. Ask if onset of patient's symptoms was associated with starting a new medication or a change in dose/ frequency of a medication. Physical examination VIPIRONNE o Perform a complete examination of pertinent systems, such as the cardiovascular & neurologic systems (especially cranial nerves), before proceeding to specific office tests of the vestibular system. 27 Ortho Lecture Notes Combined Assess for nystagmus. Nystagmus of peripheral (ie, labyrinthine) origin typically is unidirectional. Nystagmus of brainstem or cerebellar (ie, central) origin may be bidirectional & have more than one direction, For example: torsional plus horizontal movement. Pure vertical nystagmus almost always is a sign of brainstem disease & not a labyrinthine disorder. If a patient experiences pre-syncope perform auscultation of the heart & cervical vessels, determine orthostatic blood pressure & pulse. Orthostatic vital signs Carotid sinus reflex o Examine the ears for retraction, bulging or perforated tympanic membrane or inflammation. Assess hearing in both ears. (Global hearing, Weber’s, Rinne) o Orthopedic Swivel test Nylen-Barany test (Dix-Hallpike) Barany chair records eye movements Romberg's Valsalva Head-shake test The examiner vigorously shakes the patient's head in the horizontal plane from side to side for 10-15 seconds. After the shaking is stopped, the eyes are observed for nystagmus. This test can reveal latent nystagmus & indicate which labyrinth is malfunctioning. o Office examination of the vestibular system Gait test: Determine whether the patient staggers or consistently leans to 1 side or the other. Past Pointing: Ability for patient be able to touch an object with eyes open & closed to test for vestibular nerve & cerebellar function. https://www.youtube.com/watch?v=1NtDhHSGXEs Diagnostic Studies o Electronystagmography with caloric testing o Electrocochleography: Although electrocochleography is not extremely sensitive, it is highly specific for conditions related to inner ear fluid imbalance (most commonly Ménière's disease). Assess fluid imbalance (imbalance = Meniere’s) Classic Meniere’s = Vertical, Hearing loss, Tinnitus Common includes above + ear fullness o Auditory brainstem response: Testing of the auditory brainstem response (ABR) can help in the diagnosis of rare cases of microvascular compression of cranial nerve VIII in the cerebellopontine angle or root-entry zone. o Audiometry o Electrocardiogram o Echocardiogram o Chest x-ray o Lab: CBC, Glucose levels, Electrolytes, Cardiac Enzymes Conditions that induce Vertigo 28 Ortho Lecture Notes Combined Meniere’s Disease (H81.09) aka: Paroxysmal Labyrinthine Vertigo, Primary Endolymphatic Hydrops, Lermoyez Syndrome, Meniere’s Syndrome Definition: disorder that affects the semicircular canals & cochlea of the inner ear, characterized by recurrent vertigo with fluctuating hearing loss, roaring tinnitus & fullness in the ear. Epidemiology: Age: 40s-50s, can occur any age but rare after 70 Higher incidence in pregnancy 40% have bilateral involvement Etiology: Etiology is not known. It appears to be the result of the abnormal volume or composition of fluid in the inner ear (endolymph). Because no single cause has been identified, it's likely that Meniere's disease is caused by a combination of factors. FYI: Meniere’s syndrome is the diagnosis if an identifiable cause of fluid build up is determined. Pathogenesis: endolymphatic hydrops = accumulation of fluid in the endolympathic spaces. All patients with Meniere’s have endolympathic hydrops but not all patients with endolymphatic hydrops has Meniere’s Clinical presentation: Classic triad of symptoms Vertigo- Reoccurring severe vertigo, which peaks within minutes then slowly subsides over hours. o Attacks can last from 20 minutes to 24 hours. o They can occur with the frequency of many attacks each week; o can be separated by weeks, months, & even years. progressive, fluctuating low tone sensory hearing loss o Loss of Low TONES 1st tinnitus Other common symptoms o aural fullness - Sensation of fullness & pressure along ear w/decreased hearing & tinnitus, usually unilateral o pallor, nausea, diaphoresis may occur during a severe attack. o vomiting/diarrhea o anxiety o depression o drop attacks o persistent disequilibrium for days after an episode. Episodes vary in frequency & intensity – initially it starts with vertigo than progresses to fluctuating lowfrequency hearing loss. 29 Ortho Lecture Notes Combined Following the attack, a period of extreme fatigue or exhaustion often occurs, prompting the need for hours of sleep Stages of Meniere’s it is impossible to predict the timing or severity of each stage for each individual. Stage 1 – transient, short, sudden, nausea, vomiting, brief hearing loss, tinnitus o Episodes 20 min – 24 hr. o sudden & unpredictable attacks of vertigo; o usually accompanied by nausea & vomiting. o May lose some hearing during the attack which then may revert to normal, & there is often tinnitus at the same time. o Ear may also feel blocked & uncomfortable, with a sense of fullness. Stage 2 - "classical" – less severe vertigo / worsening hearing loss, tinnitus o continuing attacks of vertigo, with the attacks becoming less severe. Vertigo starts to get better after a period of worsening (even temporary remission) o Tinnitus & hearing loss often become worse. Stage 3 – Hearing loss & tinnitus getting worse & problematic, may no longer get vertigo o Hearing loss worse & on both sides o Vertigo episodes occur far less frequently & may stop altogether. o May have balance problems. o Hearing problems & tinnitus may become progressively worse during this stage. Key Examination Findings: Caloric testing = o will show a lack of response or abnormal response on the affected side. o Put hot/cold water in the ear Barany chair = will be positive Nylen-Barany = (+,-) Low pitched hearing changes Diagnostic Criteria: American Academy of Otolaryngology-Head & Neck Surgery diagnostic criteria (all must be present) vertigo o ≥ 2 spontaneous episodes o lasting ≥ 20 minutes during single attack of Meniere's disease tinnitus with or without perception of aural fullness sensorineural hearing loss confirmed by audiometry on at least 1 occasion (may be difficult to confirm in early stages of disease) other causes ruled out Diagnostic Studies: Audiometry - basic hearing test Electrocochleography (ECOG) - measures the excess fluid accumulation in inner ear. Electronystagmography (ENG) - looks for signs of vestibular dysfunction or neurological problems by measuring nystagmus. Rotary-chair testing (Barany chair) - Like a VNG, this measures inner ear function based on eye movement. MRI - rule out an acoustic neuroma or other brain tumor as a possible source of symptoms. Management 30 Ortho Lecture Notes Combined There is no evidence to support the use of manipulation although several case studies have indicated some positive results. No evidence of CMT Patients may be advised to avoid: o alcohol, caffeine, & tobacco o all of which can aggravate symptoms of Ménière's. Low salt diet = 2-3 g/day or less; Lower salt intake to under 2-3 g/day Vestibular rehabilitation therapy (VRT) o sometimes used to help with the imbalance that can plague people between attacks. Rest Meniett device (percussion) Medication: diuretics Rehabilitation strategies most commonly used are: Gaze stability exercises - moving the head from side to side while fixated on a stationary object (aimed to restore the Vestibulo-ocular reflex) An advanced progression of this exercise would be walking in a straight line while looking side to side by turning the head. Habituation exercises - movements designed to provoke symptoms & subsequently reduce the negative vestibular response upon repetition. Examples of these include Brandt-Daroff exercises. Functional retraining - including postural control, relaxation, & balance training. Avoid positions that irritate Medical Management: Medications can be used during an attack to reduce the vertigo, nausea/vomiting or both. o Diuretic if lifestyle changes are not sufficient, evidence is not great supporting the use of diuretics o Intratympanic gentamicin – chemical labyrinthectomy (vestibular ablation) Meniett device – painless micropressure pulses into the ear that may reduce excess inner ear fluid, tube is placed in middle ear In severe, unremitting cases = destruction of the labyrinth or vestibular nerve or shunting to drain endolymph. Prognosis: It is difficult to predict how Ménière’s disease will affect a person’s future. Symptoms can disappear one day & never return. Or they might become so severe that they are disabling and result in hearing loss BPPV - Benign Paroxysmal Positional Vertigo (H81.10) aka: Canalolithiasis, Cupulolithiasis, vestibulolithiasis *named for where the stones are Definition: a disorder arising in the inner ear. Its symptoms are repeated episodes of positional vertigo, that is, of a spinning sensation caused by changes in the position of the head. Paroxysmal = sudden Etiology: Idiopathic (over 50 yrs) Head trauma (under 50 yrs) Inner ear damage Migraines Pathology 31 Ortho Lecture Notes Combined Within the labyrinth of the inner ear lie collections of calcium crystals known as otoconia. Canalithiasis = the otoconia are dislodged from their usual position o Usually in utricle, but now move in the fluid of the canal. o With this form after movement of the head it usually takes < 1 minute for the fluid to stop moving o so vertigo is usually < a minute Cupulolithiasis = the otoconia adhere to cupula (sensory fibers that detect fluid movement). o This form is less common o vertigo & nystagmus can last longer; due to attachment of sensory fiber o until the head is moved out of the offending position. Epidemiology: Age: middle age to elderly. 2:1 Women to men Most common cause of vertigo = BPPV Clinical Manifestations Vertigo induced by head motion (duration: if canalithiasis < 60sec, if cupulolithiasis – variable but still shorter duration). Nausea Nystagmus o Nystagmus associated with BPPV has several important characteristics that differentiate it from other types of nystagmus. Positional: the nystagmus occurs only in certain positions Latent onset: there is a 5-10 second delay prior to onset of nystagmus Nystagmus lasts for 5–120 seconds, usually less than 30s. Visual fixation suppresses nystagmus due to BPPV focus makes it stop if BPPV Repeated stimulation cause the nystagmus to fatigue or disappear temporarily. Response fatigues w/repeat situation e.g. testing Nyalan Barany (+) Nylen-Barany &/or Dix-Hallpike = response fatigues after repeated testing o Posterior semicircular canal involvement (most common) elicits a rotatory or vertical upbeat nystagmus. Rotatory nystagmus is clockwise if left ear involved & down; counterclockwise if right ear involved & down o Anterior semicircular canal involvement – Rotatory & downbeating nystagmus on Dix-Hallpike maneuver, Upbeating nystagmus on return to sitting o Horizontal semicircular canal involvement – horizontal nystagmus on Dix-Hallpike maneuver, horizontal (opposite direction) nystagmus on return to sitting {Arch Otolaryngol Head Neck Surg 1996 Mar;122(3):281} o o o Posterior canal (Most common) = CW rotary if L involved & down (see slide) CCW is R ear involved & down Anterior Canal: Rotary & downbeating nystagmus going dow Upbeating nystagmus returning to seated Horizonal canal Horizontal nystagmus going up & down 32 Ortho Lecture Notes Combined See slide w/URL Bandt Darroff Tx o For home tx of canalolithesis If R inner ear affected the Turn head L & lay on R while looking @ ceiling Stay until sx reside up to 30 seconds or more Sit up, look R and then do other side START on the side that is affect o 2 wks, 3x /day o 3 wks 2s/day Antivertigo drugs (refer) Surgery (-) Caloric reflex tests Emesis is uncommon but possible. Diagnostic Criteria: American Academy of Otolaryngology-Head & Neck Surgery Foundation diagnostic criteria for posterior canal BPPV history of repeated episodes of vertigo with changes in head position vertigo with nystagmus elicited by Dix-Hallpike maneuver latency period (typically 5-20 seconds) between completion of Dix-Hallpike test & onset of nystagmus & vertigo nystagmus & vertigo increase & then resolve ≤ 60 seconds from onset of nystagmus Management o Canalith repositioning procedures o Epley Held 45 to side, wait for nystagmus, then straight up, then Opposite side 90 degrees o Semont – for cupulolithiasis aka livertory maneuver E.g. L posterior canal Sit on bed, lay quickly on L Then switch quickly to lying diagonally on R face for 1 M Then sit up on bed for 10 min o Manual manipulation o Medications - antivert o Surgery - sectioning the nerve to the ampulla of the posterior semicircular canal, this procedure may result in deafness. Prognosis: One third of patients remit at 3 weeks & the majority of patients at 6 months from onset. Surgery is very rarely required (less than 1%). Reoccurrence is frequent. 1/3 better in 3 weeks Most w/in 6 months if treat at home too Surgery is rarely req. WF 61 yo, episodic dizziness. Occur @ anytime of day, but worse in am when turning in bed. Also when turn head throughout day. Last 45 sec. Exam findings o Latent nystagmus w/Nylen barany o Visual fixation helps o Decreased sx w/repeat testing o 33 Ortho Lecture Notes Combined Labyrinthitis (H83.09) Etiology: In addition to viral & bacterial infections, it may be due to head injuries, stress, allergic response or adverse response to medication, & cholesteatoma. Usually result of viral or bacterial infection o Infection affects both branches of the vestibulcochlear N Sometimes from trauma stress or allergies that put pressure on labyrinth Clinical Manifestations: Vertigo may worsen with head movements Nystagmus may be present & worsen with head movements Possible hearing loss in the affected ear. Otoscope examination usually normal although higher incidence of otitis media so signs of that maybe evident. Tinnitus is possible Symptoms usually peak within 24 hours then slowly resolve over the next several weeks. May have fever, chills, ear pain, +/- hearing loss, otitis media, tinnitus, Improved sx in 1st week and gone by 2-3 month Diagnostic testing: Usually not needed. Tests will be done to rule out other causes of your symptoms. These may include: EEG Electronystagmography Head CT scan Hearing tests (audiology/audiometry) MRI of the head Warming & cooling the inner ear with air or water (caloric stimulation) to test eye reflexes Management Vestibular rehabilitation therapy is a highly effective way to substantially reduce or eliminate residual dizziness from labyrinthitis. Medications that may reduce symptoms include: Antihistamines Medicines to control nausea & vomiting Medicines to relieve dizziness Sedative-hypnotics such as Valium Treat sx, as usually self-resolving o Reduce inflammation o Help w/sleep Vestibular rehabilitation & balance training Prognosis: Severe symptoms usually go away within a week. Most patients are completely better within 2 to 3 months. Continued dizziness is more likely to last in older patients. Hearing loss may be permanent. 1 week resolves At most 2-3 weeks 34 Ortho Lecture Notes Combined In older population may have residual effects, e.g. Hearing Loss Vestibular Neuronitis (H81.2) Etiology: Paroxysmal (sudden) Souza: o Cause UNKNOWN o 50% have had common cold o Peak age 40-50 y o Theory = reactivation of dormant herpes infection in Scarpa’s ganglion o Initial severe vertigo, nausea, disequilibrium lasts a few days o Provocation by rapid head movts lasts weeks o DDX from Labyrinthitis b/c Labyrinthitis affects both Vestibular & Cochlear NN Labyrinthitis has hearing loss / Vestibular neuritis does NOT Labyrinthitis has signs of infection (fever, chills, ear pn) / Vest neur does NOT o DDX from Inferior Cerebellar infarct/hemorrhage: 25% pts have risk factor for stroke when present @ ER w/vertigo, nystagmus, disequilibrium Vest Neuronitis is Peripheral NS, so nystagmus: worse looking in direction of unaffected side = Alexander’s Law improves when fixate on object HYPO or no findings w/Caloric testing Cerebellar stroke is Central NS, so nystagmus: Not improved w/fixation May change direction Accompanied by cerebellar signs: dysarthria, ataxia, dysdiadokinesis, finger to nose, and disequilibrium is more CC than vertigo o Management: Central compensation over time on own Perform vestibular training (focus on object w/head movt in all direction Perform eye-head coordination exercises Perform balance exercises Rx in ACUTE phase: *NOTE that it may delay central compensation healing Benzodiazepines (lorazepam, diazepam) Single attack of vertigo, series of attacks, or persistent condition that occurred suddenly SUDDEN ONSET, SEVERE for DAYS, IMPROVES OVER WEEKS o Possible N/V NO HEARING LOSS B/C not cochlear N (only balance affected) Possibly acute localized ischemia Additional Clinical Information: Patient will state the vertigo: o Gradually gets better over a span of a few days to weeks. o After the first symptoms of vertigo go away, there may be a period lasting a month or more when any sudden head movement can trigger dizziness & loss of balance. 35 Ortho Lecture Notes Combined o o o o Patient tends to fall toward his or her affected side when attempting ambulation or during Romberg tests. NOT Vestibular neuronitis if any of the following findings are present: o Multidirectional, non-fatiguing nystagmus (this suggests vertigo of central origin) o Hearing loss o Other cranial nerve deficits o Truncal ataxia (suggests cerebellar disease or another CNS process) o Inflamed tympanic membrane o Mastoid tenderness o High fever Treatment: self-limiting, hydrate, vestibular rehab, o MAY need MRI to determine cause if not resolving Diagnosis o Perform Hallpike maneuver - Failure either to observe or to provoke unidirectional nystagmus casts doubt on whether the process is localized to the peripheral vestibular system. o Cerebral imaging may be necessary to assess causes. MRI over CT. Prognosis: Most patients experience complete recovery within a few weeks. A minority have recurrent vertiginous episodes following rapid head movement for years after onset Disequilibrium or Vertigo Cervicogenic Dizziness (Vertigo) Definition: It is a nonspecific sensation of altered orientation in space & dysequilibrium originating from abnormal afferent activity from the neck. Cervicogenic dizziness does not result from vestibular dysfunction and, o therefore, rarely results in true vertigo. Etiology 3 mechanisms implicated o Irritation of the cervical sympathetic nervous system o Mechanical compression or stenosis of vertebral artery o Involvement of the proprioceptors of the upper cervical spine (C0-C3) caused by overstimulation or another disorder Risk factors: Cervical trauma whiplash (flexion/extension injury) (50% of cases) o E.g. WAD, so check of concussion & head trauma too Degenerative joint disease - Less space for nn, so irritated Muscle spasm - Less space for nn, so irritated Clinical presentation: o History of neck trauma or injury. Neck pain. Likely due to proprioceptive change o “Dizziness” for minutes -hours, or longer. o Worse with neck movement or sustained postures o Possible headache, possibly nystagmus 36 Ortho Lecture Notes Combined o Upper cervical muscular tenderness. Palpation may increase dizziness. o Feels like falling & may feel off balance o Upper cervical spine segmental dysfunction o Cervical spine findings (palpatory & ROM), restrictions, o (+) Swivel Diagnostic Criteria: o Temporal relationship between neck pain & symptoms of dizziness o including time of onset & occurrence of episodes o eg., decrease pain decrease dizziness o previous neck injury or pathology o eliminate other causes of dizziness Management: o Upper cervical manipulation o Positional cervical stabilization exercises o Soft tissue modalities o Vestibular rehabilitation Prognosis: Conservative/chiropractic treatment has very high success rate. Treatment: Upper cervical manipulation Stabilization exercise, cervical Soft tisus Vestib rehab, balance Conservative chiro tx has high success rate*** Presyncope/Syncope Conditions Vasovagal syncope (R55) aka: Vasodepressor syncope, “Fainting” Definition: Temporary loss of consciousness resulting from an acute global reduction in cerebral blood flow. Etiology: Usually a trigger, most often emotional or pain that affects blood pressure o emotional stress common cause o fear o pain o venipuncture, other painful or medical procedures o prolonged standing or sitting (waiting at the alter) o hot environments, overheat o dehydration o systemic illness o alcohol 37 Ortho Lecture Notes Combined Pathology: Vasovagal syncope trigger causes a sudden drop in your heart rate & blood pressure. That leads to reduced blood flow to your brain, which results in a brief loss of consciousness. Vasovagal syncope is usually harmless. Most risk is from hitting head when fall Epidemiology: Adolescents & young adults b/c they stress out more easily F > M; elderly males Most common cause of syncope = VASOVAGAL SYNCOPE Clinical Manifestations Before a vasovagal response patient may experience: o Skin paleness or clamminess o Lightheadedness o Tunnel or blurred vision o Nausea o Dilated pupils o Weak pulse o Abnormal movements of extremities. Recovery after a vasovagal episode generally in < 1 minute. Yet, risk of fainting remains with standing within 15-30 minutes of fainting. Diagnostic Studies o Tilt table test - to determine blood pressure of patient at different positional levels. Dx study of choice. o Blood Volume determination - to evaluate intravascular pressure & blood flow. o Autonomic reflex testing - series of different test to monitor blood pressure, blood flow, heart rate, skin temperature & sweating in response to certain stimuli. Management: Patient usually revives in less than a few minutes Treatment may not be needed however if occurrences become frequent the following maybe done. o changes in medications or new medications. o Wearing support garments or compression stockings to improve circulation o Making certain dietary changes such as eating small, more frequent meals; increasing salt, fluid & potassium (note: may need to consult with allopathic physician before making these recommendations); & avoiding caffeine & alcohol. o Education in taking certain precautions when changing positions from sitting to standing. o Elevating the head of bed while sleeping. o Avoiding or changing the situations or “triggers” that cause a syncope episode. Carotid sinus syncope (G90.01) aka: Carotid sinus hypersensitivity, “Tight-collar” syndrome Definition: A brief unconsciousness from impaired blood flow to the brain. Unlike the ordinary faint, this syncope is not preceded by pallor, nausea, & sweating. It results in dizziness or syncope from transient diminished cerebral perfusion. 38 Ortho Lecture Notes Combined Recurrent dizziness Nonaccidental unexplained falls Sx produced by head turning, extension Collared shirts Essentially increased pressure on the carotid sinus makes the body think has high BP, so it drops BP Two Categories of Carotid Sinus Syncope: o Spontaneous carotid sinus syndrome refers to a clinical situation in which the symptoms can be clearly attributed to a history of accidental mechanical manipulation of the carotid sinuses (taking pulses in the neck, shaving) & is reproduced by carotid sinus massage. Spontaneous carotid sinus syndrome is rare & accounts for about 1% of causes of syncope. o Induced carotid sinus syndrome refers to a clinical situation in which a patient has no clear history of accidental mechanical manipulation of the carotid sinuses & has a negative result from workup for syncope, except for a hypersensitive response to carotid sinus massage, which can be attributed to the patient's symptoms. Induced carotid sinus syndrome is more prevalent than spontaneous carotid sinus syndrome & accounts for the bulk of patients with an abnormal response to carotid sinus massage observed in the clinical setting. o Etiology: o Most common causes = coronary artery disease, hypertension, then Neck tumors. o Other causes include orthostatic hypotension, Alzheimer's or Parkinson disease or Concurrent medication with digitalis, beta-blockers, & methyldopa. o It may be associated with an identified precipitating trigger such as o turning of neck o wearing a tight necktie o shaving the neck o neck malignancy Pathology Nucleus tractus solitarii in brainstem is directly / indirectly activated by triggering stimulus, resulting in simultaneous enhancement of parasympathetic nervous system (vagal) tone & withdrawal of sympathetic nervous system tone resulting in a spectrum of hemodynamic responses: 1. On one end of the spectrum is the cardioinhibitory response, a. Drop in heart rate (negative chronotropic effect) & contractility (negative inotropic effect) b. Leads to decreased cardiac output, significant enough to cause loss of consciousness. c. It is thought that response results primarily from enhancement in parasympathetic tone. 2. On the other end of the spectrum is the vasodepressor response, a. Drop in blood pressure (to as low as 80/20) without much change in heart rate. b. Occurs due to vasodilation, likely from withdrawal of sympathetic nervous system tone. 3. Majority of people with vasovagal syncope have a mixed response somewhere between these two ends of the spectrum. Epidemiology Rare prior to 50 yrs M>F 39 Ortho Lecture Notes Combined Clinical presentation: o Recurrent “dizziness” (presyncope/lightheadedness) o Recurrent syncope o Non-accidental, unexplained falls o Symptoms produced by head turning or wearing garments with tight-fitting collars. o Possible prodrome or retrograde amnesia for the syncopal event o Typical trigger factors are shaving, head turning, neck extension or tight collars. Even mild stimulation to the neck may cause marked bradycardia & hypotension. The features of CSH may occasionally occur without any stimulation. o Auscultation for a carotid artery bruit is essential in the evaluation of carotid artery occlusion. o Carotid sinus massage - considered positive if asystole longer than 3 seconds or a drop in systolic BP by 50 or more (carotid sinus massage should not be done in chiropractic office) Management o Lifestyle modification: o Avoid triggers that increase pressure on the carotid sinus o Loose clothing with open collars may be helpful. o Maintain adequate fluid intake. o Learn to be aware of warning symptoms. o There has not been shown to be any consistent benefit of medical therapies. o Cardiac pacing with a permanent cardiac pacemaker, however again not shown to be highly effective. o Surgical denervation of the carotid sinus. Not commonly performed. Prognosis: o Untreated symptomatic patients o have a syncope recurrence rate as high as 62% within 4 years. o Patients treated with a pacemaker have fewer syncope attacks but may experience a recurrence rate as high as 16% in 4 years. Orthostatic hypotension (I95.1) aka: Postural hypotension, Orthostasis Definition: a drop in systolic pressure of at least 20mm Hg and/or diastolic pressure of at least 10 mm Hg within two to five minutes of standing up. Symptom is sometimes caused by blood pooling in the lower extremities upon a change in body position. Loss of blood flow to head problems w/sit to stand= get dizzy, blurry vision Etiology: Orthostatic hypotension can be caused by many different things, including: o Medications are the most common cause. o Hypovolemia ~ Dehydration another very common cause. Caused by Fever, vomiting, not drinking enough fluids, severe diarrhea & strenuous exercise with excessive sweating. o Heart problems. Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack & heart failure. o Diabetes. Untreated diabetes can cause dehydration by causing frequent urination. 40 Ortho Lecture Notes Combined o o Nervous system disorders. Some diseases, such as Parkinson's disease, multiple system atrophy (Shy-Drager peripheral neuropathies) & amyloidosis, can disrupt your body's normal blood pressure regulation system. Associated with Addison's disease. Pathology It is due to a lesion of the baroreflex loop, which senses a change in blood pressure & adjusts heart rate & activates sympathetic nerve system fibers to cause the blood vessels to narrow & correct blood pressure Clinical presentation: Lightheadedness/presyncope is most common Sx when patient stands up Symptoms tend to resolve quickly (a few seconds) blurred vision weakness/leg buckling fatigue syncope – may occur & can be gradual or sudden chest pain, orthostatic dyspnea, neck pain, & headaches are less common Sx Classification of Orthostatic Hypothension: initial orthostatic hypotension - lightheadedness/dizziness, visual disturbances a few seconds after standing *may be dehydrated younger person classical orthostatic hypotension - dizziness, pre-syncope, fatigue, weakness, palpitations, visual & hearing disturbances 30 seconds to 3 minutes after standing middle aged delayed (progressive) orthostatic hypotension - prolonged prodrome dizziness, fatigue, weakness, palpitations, visual & hearing disturbances, hyperhidrosis, low back pain, neck, or precordial pain followed by rapid syncope 3-30 minutes after standing *older person Evaluation of Orthostatic Hypotension: 1. Review medications the patient is taking BP meds? 2. Review coexisting medical disorders 3. Determine the relationship of episodes to meals, exercise, straining, valsalva, standing up 4. Orthostatic (postural) vitals = a. BP & Pulse in the supine position & repeat in standing positioning after 3 minutes (or seated position if the patient appears to be unsteady) i. Positive = decrease in systolic blood pressure ≥ 20 mm Hg or ≥ 10 mm Hg in diastolic blood pressure within 3 minutes of standing compared to sitting or supine ii. Decrease in systolic by 10+ mmHg & increase in heart rate by 30+bpm 5. Neurological work-up - In patients with neurogenic causes of orthostatic hypotension, the heart rate may not increase (Engstrom, 1997) Diagnostic studies o Cardiac work-up: ECG, Tilt table testing, Holder monitor, Stress test, Echocardiogram o Blood work: anemia or diabetes Management o Review medications & possible referral for changes o Increased water & electrolyte intake to help prevent dehydration. o Review daily behaviors o Avoid activities in the morning or after immediately after eating 41 Ortho Lecture Notes Combined Avoid extreme heat Teach slow position changes to avoid episodes. Sleep in a slight incline. Avoid Alcohol Increased frequency of meals (4-6 meals a day) Coffee intake shown to help (2 cups). Compression stockings may be considered to help prevent fluid from pooling in the legs when a person is sitting or lying down. o Teach patient to perform isometric exercises (such as squeezing a rubber ball or a towel for a few minutes) before assuming an upright position. These exercises will raise blood pressure & may prevent a significant drop in blood pressure when they stand up. Upper cervical adjustments may help condition. Caution should be used to make sure your hand placement is not contacting the carotid sinus. Referral o MD may prescribe a medication to treat the orthostatic hypotension, drugs that work by increasing blood volume or by constricting (narrowing) blood vessels. o o o o o o o o o Cervical Spine & Brachial Plexus Conditions Objectives: 1.

Cervical disc disease with radiculopathy (M50.10) aka Degenerative intervertebral cervical disc, aka Cervical disc syndrome, aka Intervertebral disc disorder Definition: o Impingement of a cervical nerve root secondary to: disc herniation &/or degenerative disc disease, o characterized by: unilateral shooting, shock-like pain in the upper extremity, neck pain & possible sensory &/or motor deficits (even a VERY light touch will disrupt signal) o Usually history of neck pain & or cervical trauma. A cervical disc tends to degenerate naturally over time becoming more ligamentous than disc-like by age 50. 70-75% of cases -caused by foraminal encroachment due to degeneration. Normal motion helps maintain function Classification: o Bulge - involves more than one quarter (25% of disc) of the circumference of a disc; 42 Ortho Lecture Notes Combined bulges are always gradual & broad often involve the whole disc (circumferential bulge). It is responsible in part (along with endplate bowing) for the disc height loss that is seen with aging. Nucleus propulsus pushes out on annulus o Protrusion – less than 25% of the disc circumference focal or localized abnormalities of the disc margin. o Extrusion – defect in annulus, Nucleus propulsus not contained allows displacement of the nucleus beyond the confines of the disc o Sequestration – extruded material separates from the rest of the disc (floating fragment) Dislodged piece can resolve or be problematic Epidemiology: Acute Disc o M=F, o age peaks in mid to late 30’s o associated with trauma Degenerative Disc – o F>M, o Prevalence is: 10% in 20s up to 90-100% in 70+ yrs o Levels: C6-C7*, C5-C6*, C4-C5 *most common C7 root is found affected in 37%-75% of the patients. C6 is found affected in 15.8% to 48% of the patients. The other cervical levels are rarely involved. (Borenstein, 1996) Etiology: Acute cervical spine trauma (flexion/extension injury) o disc function is to absorb shock, yet forces can overwhelm disc resilience Twisting action of the head/neck combined with compression Degenerative joint disease (etiology of degeneration sometimes unknown usually thought to be secondary to old trauma) Theories: o White & Panjabi propose that disk failure is due to tensile load o Farfan feels disk injury is due to combined torsion & compression loads. Risk Factors Driving vibrating equipment *constant repetitive stress Recurrent lifting of heavy objects (associated with job) *constant repetitive stress Smoking *weakens everything Pathogenesis: Acute disc herniation causes radicular pain through chemical radiculitis o in which proteoglycans & phospholipases released from the nucleus pulposus mediate chemical inflammation and/or direct nerve root compression. The chemical radiculitis is a key element in the pain caused by HNP because nerve root compression alone is not always painful unless the dorsal root ganglion is also involved. Herniation may induce nerve demyelination with resulting neurologic symptoms. Forms of Disc herniations: Acute disc herniation (soft disc) 43 Ortho Lecture Notes Combined o Manifest: acute neck pain & paraspinal muscle spasm, with radicular symptoms/signs. o Patient usually doesn’t have a history of neck pain. Patients tend to be younger & there may have been a traumatic etiology (high energy injury or awkward twisting or turning). Soft discs resolve more frequently than hard discs. (Scherping, 2002) o Chemical radiculitis is key component of acute herniations o Younger patients – more imbibition, hydrated, so more nucleus propulsus Degenerative disc disease (hard disc) o Found in patients age 45+ degeneration & less imbibition o Most common form of disc disease more people age than are injured o Onset is more insidious severity increases w/time o Radiculopathy more common o Usually have episodic neck stiffness & pain. (Scherping, 2002). o History of trauma noted only in about 15% of cases. Clinical Presentation Posterior, Posterior-lateral neck pain, May or may not have persistent radicular symptoms -pain, paresthesia, weakness in arm Typically unilateral Neck pain is persistent even at rest due to chemical radiculitis Exacerbation with extension Flexion may push disc further out & cause pain Antalgia is possible - lean to one side Possible edema, erythema Tenderness Cervical muscle spasms of mm innervated by the inflamed NN A/hypotonicity, Myotomal weakness, A/hyporeflexia, Dermatomal changes in sensation o of mm innervated by the inflamed NN Cervical distraction may relieve arm pain open IVFs Shoulder depression may reproduce complaint on the side of head deviation Cervical ROM decreased & often provoking Diagnosis requires: 2 clinical signs + 2 clinical symptoms + imaging* required Clinical Prediction Rule for Identifying Cervical Radiculopathy (Wainner RS, Irrgang JJ, Boninger ML, Delitto A, Allison S.

Cervical Myelopathy (M47.12) Definition: Damage/irritation/inflammation of spinal cord that can manifest with: difficulty with manual dexterity, gait disturbance, upper motor neuron signs (Hoffman sign, Babinski sign, hyperreflexia, & clonus), & Other long tract signs: o alteration in: proprioception, touch, pain, temperature, balance, etc 45 Ortho Lecture Notes Combined Epidemiology: +45 years. Most common cause of spinal cord dysfunction in individuals older than 55 years of age. Etiology STIFD Spondylosis Tumor Ischemia Fractures/dislocations Disc herniation Pathogenesis: Direct pressure &/or ischemia to the cord alters function of the tracts Decreased blood flow Clinical Presentation Vary depending where on cord: Anterior=motor, Posterior = sensory Symptoms & signs vary depending on: o Level of involvement (C1-C7) o Part of cord that is involved (anterior vs posterior vs lateral aspect of the cord) Overlapping symptoms of posterior & anterior cord involvement are usually: o Headaches, neck stiffness, shoulder pain, o Paresthesias & other radicular signs. The timing of the appearance of symptoms & their progression is also highly variable from person to person. o Rate of progression of an individual’s symptoms may change over time, with periods of relatively rapid change interspersed with periods of stability or minimal progression.

E.g. If it occurs only once a week = not be considered unstable but if it occurs 5-8 times a day, instability considered as a diagnosis. o Dysfunction often leads to issues with other tissues in the neck leading to a disruption of normal everyday activities. Sharp neck pain with motion or position & possible upper back pain &/or headaches. Pain is provoked by sustained weight bearing positions & better when non-weight bearing Muscle spasms are common due to increase contraction to try a provide stability.

Increased breaks. Sleeping habits Diet: o Decreased sugar & caffeine. o Increased vegetable intake. Supplementation: Vitamins A, C, D, E & B complex (esp B6 & Niacin) anti-inflammatory Medical Management: Drug therapy = analgesics, anticoagulants, muscle relaxants, botulism toxin injection into scalenes Surgery: Resection of: cervical rib, supernumerary bony abnormalities (not a high success) or fibrous bands Other Brachial Plexopathies Erb-Duchenne, Klumpke, Horner’s Syndrome The brachial plexus consists of nerves that originate in the fifth, sixth, seventh & eighth cervical (C5-C8), & first thoracic (T1) spinal nerves, & innervate the muscles & skin of the chest, shoulder, arm & hand. Brachial plexus injuries, or lesions, are caused by damage to those nerves Erb’s Palsy (P14.0) aka: Erb-Duchenne Paralysis, Waiter’s tip deformity, Flail arm Definition: Paralysis of the arm by injury to the upper group of the arm's main nerves, specifically the severing of the upper trunk C5–C6 nerves. These form part of the brachial plexus, comprising the ventral rami of spinal nerves C5–C8 & thoracic nerve T1. Although injuries can occur at any time, many brachial plexus injuries happen when a baby's shoulders become impacted during delivery & the brachial plexus nerves stretch or tear. Epidemiology: Most commonly seen during deliveries, however can be seen with trauma. Etiology: Dystocia - an abnormal or difficult childbirth or labor o infant's head & neck are pulled toward the side at the same time as the shoulders pass through the birth canal o Excessive pulling on the shoulders during a cephalic presentation (head first delivery), or by pressure on the raised arms during a breech (feet first) delivery 52 Ortho Lecture Notes Combined Clavicle fracture o Unrelated to dystocia in neonates Trauma to the head & shoulder o which cause the nerves of the plexus to violently stretch (any age) Direct violence, including gunshot wounds & traction on the arm, or attempting to diminish shoulder joint dislocation. The level of damage to the constituent nerves is related to the amount of paralysis. Clinical presentation: Arm straight & medial rotation & pronation “Waiter’s tip” loss of sensation paralysis & atrophy of the supraspinatus & infraspinatus are most commonly involved in severe conditions the deltoid, biceps, subscapularis and/or brachialis muscles arm hangs by the side & is rotated medially; the forearm is extended & pronated arm cannot be raised from the side; all power of flexion of the elbow is lost, as is also supination of the forearm. The resulting biceps damage is the main cause of this classic physical position commonly called "waiter's tip." Treatment: Acute injury - Referral Chronic - Rehabilitation. o Some brachial plexus injuries may heal without treatment. o Many children who are injured during birth improve or recover by 3 to 4 months of age. o Treatment for brachial plexus injuries includes physical therapy and, possibly, surgery. Klumpke Palsy (P14.1) Bottom of brachial plexus Definition: a paralysis of the arm caused by injury to the upper group of the arm's main nerves, specifically the severing of the lower trunk C7-8 & T1 nerves. These form part of the brachial plexus, comprising the ventral rami of spinal nerves C5–C8 & thoracic nerve T1. Epidemiology: Most commonly seen during deliveries however can be seen with trauma, cervical ribs, or tumors. Etiology: avulsion injuries caused by excessive abduction (person falling from height clutching on object to save himself) cervical rib lung metastasis in lower deep cervical lymph nodes. Arm pulled in overhead position Clinical presentation: Paresis/paralysis of all small hand muscles (ulnar & median nn), clinically presents “claw hand” Extension: Wrist because of the unopposed wrist extensors, Hyperextension: MCP & flexion of IP joints due to loss of intrinsic muscles. Treatment: acute = referral to a neurologist chronic = rehabilitation 53 Ortho Lecture Notes Combined Horner’s Syndrome (G90.2) Definition: avulsion of the T1 root resulting in interruption of the T1 sympathetic ganglion results in interruption of sympathetic nerve supply = Interrupts innervation to the eye Etiology (partial list): Trauma to the brachial plexus Tumors (eg, Pancoast) or infection of the lung apex Dissecting carotid aneurysm o In one study, 44% (65/146) of patients with internal extracranial carotid artery dissections had painful Horner syndrome, which remained isolated in half the cases. Migraine Cervical rib Cervical spondylosis Clinical presentation: Miosis results from loss of sympathetic pupillodilator activity Ptosis results from loss of sympathetic tone to the eyelids dropping eye lid Anhidrosis is variable & depends on the site of the injury to the sympathetic pathway Pseudo-enophthalmus o (appearance of a sunken eyeball) but it doesn't truly occur, it is an illusion created by the ptosis. Eye change color In early Horner's the pigmentation of the iris may be affected, the eye may change color. Diagnosis: Ciliospinal Reflex - the eye will be abnormal. Treatment: Referral to Neurologist.

Rotator Cuff Tears (M75.100) Definition: Partial (micro tears) tears: Grade 1 – 2 strains Typically found In a young, active patient o may include an avulsion fracture from greater tuberosity. Degenerative cuff failure, oft starts with partial thickness defect on deep (under) surface near attachment of supraspinatus @ greater tuberosity. Full Tear: Grade 3 strain – all the way torn Common also in older people RCT commonly misdiagnosed as: tendonitis, bursitis, impingement synd. may actually be a rotator cuff tear/ failure of the deep surface fibers of the rotator cuff. The degree that intact fibers hypertrophy, strengthen, or adapt to stabilize the tear & take up function of damaged fibers is unknown. Etiology: Possible mechanisms include: repetitive stress acute trauma normal wear & tear. degenerative changes – Impingement Syndrome Neer Stage 3 3 TYPES OF Partial TEARS: Bursal side tears – likely due to subacromial impingement Articular-sided tears – likely from trauma to a degenerated tendon. (More common) Intratendinous tears - result from differential shear stress within the supraspinatus tendon. 55 Ortho Lecture Notes Combined Epidemiology: More common after 40 yrs (degenerative) after 40 years, ~ 30% of patients will have cuff tears after 60 yrs, up to 80% of patients asymptomatic full-thickness tears present in o 13% of the population age 50-59 o in over 50% of people 80+ years old Increased incident in sports (throwing athletes) & some occupations (construction) Most common tendon: supraspinatus RCT = most common cause of shoulder pain RC pathologenesis Intrinsic o Aging tendons lead to micro tears AGE & microtears o Eccentric tensile overload (throwing) can lead to tearing OVERUSE o Compromised vascular supply leads to a critical avascular zone AVASCULAR Extrinsic o Compressive forces on cuff type III acromion, superior migration of humeral head, OA, thickening of coracoacromial ligament COMPRESSION Clinical Presentation: May be asymptomatic in SIS Neer stage 3 patient *hooked acromium S - Minimal to severe pain Q - Dull, achy pain deep in the shoulder R - Refers to deltoid tubercle *If pt comes in w/shoulder pain, ALWAYS PALPATE ROTATOR CUFF Prov – o Movements above shoulder height.

Immobilization is important to decrease the risk of a repeat dislocation. o 1st dislocations are immobilized in an external rotation position, esp in those <30 yrs. If recurrent: possible to reduce in office& then REHAB to prevent recurrence. Recurrent dislocations may be immobilized in a regular sling. Stimson technique – lie prone on table, weight arm 1-15 and “hang out” Kocher – Traction. Flex elbow. ER. ABD, IR. Self-Correction - If common, show patient how to hold knee extend head and push knee: o IPSI knee bent @ 90 o Clasp hands around knee o Extend neck o Lean backwards Prognosis: normal function in 12-16 weeks = Uncomplicated rehabilitation & healing typically require surgery: *less favorable outcome w/conservative o Traumatic instability, o Connective tissue disease o Instability secondary to repetitive overuse 61 Ortho Lecture Notes Combined Post-surgical Rehabilitation: Recovery post-surgery depends upon the type of procedure the surgeon performs. Usually: o ROM of: hand, wrist, elbow begin day after surgery. o Write, Eat within 3-7 days after surgery. o Initiate supervised PT program @ 1-4 weeks o Full ROM usually returns after 6-8 weeks. o Strength usually returns ~3 months. o Driving = several weeks. o Return to work or sporting activities depends on specific nature & demands of that activity, can take up to 1+ years for heavy laborers or high level athletes. Focus of REHAB? Stabilize joint & rehab GH Instability - (Glenohumeral) (Unspecified Recurrent dislocation – M24.419) Definition: Any condition that causes excess motion of the GH joint. joint instability = common disorder of shoulder. Instability can occur in all directions, including anteriorly, posteriorly, inferiorly, multi-directional depending on injury (from most to least common). Types of Glenohumeral Instability: T.U.B.S. (Torn loose) o Trauma o Unidirectional o Bankart o Surgery A.M.B.R.I. (Born loose) o Atruamatic o Multidirection o Bilat o Rehab o Inf capsule shift Etiology: Acute traumatic instability (dislocation) TUBS o Initially the instability may not be apparent & pain is only complaint. Repetitive microtrauma (Overuse) AMBRI o Overhead activities Causes stretching of anterior stabilizing structures. Labrum fraying & avulsion, capsular laxity, glenoid & humeral articular erosions. o Functional instability without excessive capsular/ligamentous laxity falls into this category. Congenital laxity AMBRI 62 Ortho Lecture Notes Combined Epidemiology: Instability is more likely in: Younger active patients o Age at the time of dislocation = biggest determinant of future recurrence. Recurrences rom anterior glenohumeral instability Most commonly in patients younger than 20 years. Before 20 Yrs = 70-100% more likely to recur Patients with concurrent RCT *once injure Rotator cuff, then more impact on GH Males > Females Higher in baseball pitchers Direction of instability: Anterior>posterior>inferior/multidirectional Clinical Presentation HX findings o Previous acute injury/dislocation o Repetitive activity the patient engages in o Paresthesia when carrying heavy objects by side – possible inferior instability o Provocation when pushing (e.g., pushing heavy door open) – possible posterior instability o Repetitive Popping, clicking, crepitus – possible labral tear o Dead arm syndrome – anterior subluxation Athlete = sharp pain on extreme external rotation or after a blow to the shoulder. Can cause of loss of muscular control over the extremity. Severe pain usually subsides quickly, but soreness & weakness persist for a time o Palpation: Tenderness over all musculature & joints of the shoulder Possible inflammation Feeling of instability – o “shoulder will pop out”; “slipping out” when throwing (possible anterior instability) o Vague shoulder pain/discomfort/fatigue/weakness Possible findings: o Atrophy o Winging of the scapula o Signs of dislocation o DDX: observe joint motions of the GH, AC, SC joints ROM testing - look for abnormal motions & increased motion. Signs of "giving away" Muscle testing = signs of weakness (+) Orthopedic tests : Apprehension / Fulcrum + Relocation PERFORM Neurological tests. Results maybe negative. 63 Ortho Lecture Notes Combined Diagnostic studies: Plain film - looking for bony deformity (e.g. Hill-Sachs) or Glenohumeral malposition. US: signs of rotator cuff damage MR: evaluate… o Labrum (Bankart) o Cuff (strain, atrophy, tendinosis) o Joint (effusion) Treatment: Goal of therapy is to return joint to proper function & pain free ROM Increase strength of RC & surrounding shoulder muscles to prevent further instability and/or dislocation. Phase I – pain & inflammation control Rest (restrict overhead activity – pushing, pulling, lifting, reaching) Pain control (NSAIDs or homeopathic; ice & modalities for pain; possibly immobilize); AVOID mobilization/manipulation (esp distraction & ext rotation) Gentle ROM - especially light PROM if shoulder is in immobilizer • decrease mm guarding • Prevent capsular contractures DO IN SCAPULAR PLANE Immobilizer (unstable shoulder) in acute cases • <20 yrs = up to 3-4 wks • >30 yrs = 10 – 14 days • 40 yrs = only a few days Phase II – ROM & strengthening for RC & scapular stabilizers (serratus anterior, pectoralis, latissimus) ROM exercises = Codman’s, pendulum wall crawl), • Perform initially in sagittal or scapular plane inferior capsule is not twisted during elevation stress minimized on anterior & posterior capsule & rotator cuff Scapulothoracic – • start with protraction/retraction, • proceed to elevation/ depression Isometric exercises followed by isotonic exercise. • Start adducted, forward-flexed position reduces stress on glenohumeral joint • Progress to abduction in scapular plane ROM performed in pain free manner Note: • Apply ice pre & post exercise to minimize pain/edema • Tape can help rehabilitation by reducing pain & edema. Phase III - endurance program; goal =reach 90% strength in injured shoulder vs. uninjured shoulder Proprioception retraining (dribbling, ball toss, balance board) Mobilize other joints: AC, SC, Scapulothoracic articulation & possible one direction of the GH capsule (posterior capsule maybe tight in anterior instability) 64 Ortho Lecture Notes Combined Muscle strengthening ***PAIN FREE Supraspinatus • greatest activity occurs w/ patient prone & humerus abducted 100 deg + ER 90 deg. • So strengthen in this position Biceps - (anterior stabilizing function) • best to train for endurance vs. hypertrophy. Latissimus dorsi – assists deceleration of throwing motion • Strengthen with theraband or pulley system. • Limit extension when working lats so anterior capsule is not stretched. Phase IV – JOB/SPORT specific progressively increase activity level to sport- or job-specific level Push-up against a wall • Then traditional push-up on floor Then push-up off a tilt board or medicine ball Then start Plyometric training Prognosis: LESS FAVORABLE IF: Experience traumatic instability, have connective tissue disease, have instability secondary to repetitive overuse have a less favorable outcome with conservative care & typically require surgery. Despite a course of physical therapy in which full shoulder motion & strength are restored, shoulder may still be loose or unstable. Treatment options then consist of 1) activity modification & 2) surgery. Activity modification is primarily an option for patients who experience instability only with certain activities such as playing basketball or overhead racquet sports. In these patients, avoidance of the activity can completely eliminate episodes of subluxation or dislocation. Surgical treatment is considered if: • Not willing to give up the activities or sports that provoke their episodes, • In patients w/instability during routine daily activities (dressing, sleeping, etc) or work. Labral Tears (Unspecified sprain – S43.409A; Sup Glenoid Labrum Lesion – S43.439A) Definition: Injury to the fibrocartilaginous rim attached around the margin of the glenoid cavity. Etiology: Traumatic injury include: FOOSH: shoulder flexed & externally rotated compression injury A direct blow to the shoulder A sudden pull, such as when trying to lift a heavy object A violent overhead reach, such as when trying to stop a fall or slide 65 Ortho Lecture Notes Combined Repetitive/overuse include: Throwers Weightlifters Repetitive motions Age related changes Epidemiology: Incidence is unknown Type II & Type I = most common Labral Tear Types: Superior - The most common aka SLAP lesion. Inferior e.g. Bankhart Four types of SLAP Lesions: *types 2 & 4 = instability and can fix w/laparoscopic surgery Type 1: PARTIAL IN LABRUM “frayed” o Partial tear & degeneration of superior labrum, where edges are fray along free margin, but labrum is not completely detached. Type 2: FULL LABRAL TEAR = Most common type of SLAP tear. o Superior labrum is completely detached from glenoid w/ injury (often shoulder dislocation). o Leaves a gap between articular cartilage & the labral attachment to the bone. o Further subdivide into anterior, posterior & combined AP lesions. o Surgical Type 3: BUCKET HANDLE W/CLUNKING o “bucket-handle” tear of the labrum, where torn labrum hangs into joint & causes symptoms of “locking” & “popping” or “clunking”. Type 4: TEAR INTO BICEPS TENDON * o Tear of the labrum extends into long head of biceps tendon. o Surgical Types 2 & 4 can cause shoulder instability that is only remedied by arthroscopic reattachment of the labrum to the glenoid. Types 1 & 3 do not cause instability but the patient may need arthroscopic debridement. Clinical Presentation Pain usually with overhead activities or cross-body movements Deep Pain hard to localize but in joint Catching, locking, popping, grinding Crank test Occasional night pain or pain with daily activities Sense of instability in the shoulder especially with arm raised Decreased range of motion (especially over 90 degrees of abduction) Weakness, Loss of strength Tenderness: superior anterior GH joint. Decreased ROM above shoulder height Weakness above shoulder height + Ortho tests: “CARLS” cluster 66 Ortho Lecture Notes Combined Diagnostic Studies X-ray = May be normal o show loose bodies, degenerative changes o show an avulsion (Bankart's or Hill-Sach’s), o diminish size of the subacromial arch MRI = May miss smaller tears o cannot reliably make the diagnosis in larger tears of the labrum CT-arthrogram (with contrast) = 80-85% accurate. Arthroscopy – BEST o The best way to make the diagnosis of labrum tearing. o Unfortunately an operative procedure. Treatment: Activity modification/rest PROM exercise Light exercises as those mentioned for instability rehab starting with arm by side of body Scap stabilization exercises Modalities for symptom control. Analgesics for pain control If NO improvements in 2 to 4 weeks, surgical consult recommended. Surgery: Takes 3-4 months post-surgery for shoulder to be completely healed Case: WF, 19, collegiate volleyball player presents following laser assisted capsular shrinkage w/tingling in the 1st, 2nd & 5th digits w/pain in ant shoulder upon blocking & overhand motions.

Age: between 4th& 7th decades Gender: females > males Extremity: usually the non-dominate arm o although bilateral involvement in 6-50% of cases o simultaneous involvement in about 14% of cases Etiology: Primary (Idiopathic) Secondary o Intrinsic Acromioclavicular joint arthritis AC arthritis Rotator cuff tendinosis/tear Bicipital tendinosis o Extrinsic Cardiac disease & cardiac surgery surgery Neurologic disorders with impaired consciousness or hemiplegia neuro Pulmonary disease (tuberculosis, antituberculosus drugs, carcinoma) Shoulder trauma or humerus fracture trauma o Systemic Autoimmune response AI Diabetes mellitus (4.3%) Thyroid disease (hyper- & hypothyroidism) Pathogenesis: Initially inflammation develops in & around the axillary fold & anterior joint capsule, followed by adhesions & fibrosis of the synovial lining, then thickening & contraction of capsule, followed by decrease in joint volume Stages/Presentation: Painful stage Frozen (adhesive) stage Thawing (resolution) stage Painful stage: o Severe pain & stiffness occurs with any movement of shoulder o Rest pain & worse at night o Onset is insidious o NSAIDs no help 72 Ortho Lecture Notes Combined o Motion (AROM & PROM) aggravates & slowly starting to lose motion (capsular pattern of limitation). o Possible joint glide restrictions o Findings not clear so may be difficult to diagnose in this stage o Lasts 10-36 wks o Gradual diminution of articular volume (as assessed on arthrography); Frozen (adhesive) stage: o Pain may begin to diminish during this stage, yet shoulder is stiffer & ROM decreases notably. o Lasts 4-12 months o Stiffness & severe loss of motion o ADLS are impaired o Pain is less pronounced, but is severe at extremes of motion o External rotation/abduction are most affected (both AROM & PROM) w/ same pain o Isometric muscle tests are not as provoking & strong when tested by the side of the body o Atrophy of deltoid & rotator cuff (supraspinatus) may be present o Dysfunction of the AC, SC, & scapulothoracic articulations may be present o Trigger points & muscle spasms are common Thawing (resolution) stage: o Range of motion in shoulder begins to improve – possibility of full recovery (40% have slight persistent limitation in motion; 10% have gross limitation in motion) o Pain continues to decrease o Lasts 12-42 mos o Spontaneous improvement in ROM Diagnostic Studies: X-rays to make sure there is no other problem such as arthritis, may see superior migration of humerus. MR may show thickening of the capsule, synovium, coracohumeral &/or inferior glenohumeral ligament Arthroscopy has been described in 4 stages o stage 1 - pre-adhesive stage, mild erythematous fibrinous synovitis over entire joint especially in axillary fold, no limited motion, could be confused with rotator cuff tendonitis o stage 2 - acute adhesive synovitis, erythematous thickened synovium spreading across axillary fold to humeral head o stage 3 - synovium less erythematous & less reactive, adhesions matured o stage 4 - synovitis abates, joint capsule severely contracted, chronic adhesive phase, severely restricted glenohumeral motion Management: Phase 1 Modalities Analgesics/NSAIDs Avoid mobilization & adjustive techniques to GH joint, may work on the other joints Exercise therapies such as Codman’s & isometric exercises to tolerance to help with mobility Sleep on unaffected side Oral corticosteroids – can reduce pain & slightly increase motion but duration is only a few weeks Corticosteroid injections – may have more benefit in the initial freezing stage Phase 2 Continue pain management 73 Ortho Lecture Notes Combined Ultrasound helpful prior to stretching Proprioceptive training with passive stretching Light mobilization & manipulation can be performed per patient tolerance Possible Manipulation under anesthesia – rupture the fibrotic buildup. The patient may require intensive pain control & physical therapy afterward. The technique has also been reported to cause humerus fracture & vascular & neurologic injury; another major concern is articular cartilage injury. The incidence of complications is low. Possible Capsular distention (Hydroplasty)–injecting saline & steroid into the capsule to increase joint volume – it provides a short term decrease in pain & increase in motion. Phase 3 Continue stretching & other activities (mobilization/manipulation) to improve ROM Increase strengthening exercises for prevention Surgical capsular release. This procedure is done arthroscopically or via incision. Contracted tissues are directly visualized & released. Reports indicate that patients are 90% pain free & have normal to near normal motion within 3 months after surgery. Little League Shoulder Additional Information Epidemiology: Pitchers who throw curve ball or sliders are at increased risk. Treatment: Due to the nature of the injury rest is the best therapy (usually 3 months recommended, although full force throwing may take up to 12 months), then strength training for the arm & back can help to help restore balance to muscles. When return to sport occurs, proper training in throwing technique will help prevent injury. Following the proper guidelines for young pitchers can help prevent injury. Age of Athlete Pitch limit per day. 17-18 105 13-16 95 11-12 85 10-Under 75 Number of Pitches Thrown 1-20 21-40 41-60 61+ Days of Rest O 1 2 3 Prognosis: Low risk of permanent injury; small chance of early growth plate closure, which may result in a shorter arm.

Repetitive, forceful pushing & pulling, bending of the wrist, gripping, & pinching can also stretch & irritate the nerve. Sometimes direct blow to outside elbow injures radial nerve. Constant twisting arm movements- common in assembly work, pinches radial nerve leading to radial tunnel syndrome. It can also be caused by tumors Where NN passes under supinator mm To distinguish from lateral epicondylitis: RTS is a few centimeters distal from lateral epicondyle Clinical Presentation Stabbing, cutting, piercing &/or achy/fatigue pain at the proximal lateral forearm that may radiate down the arm Pain a few centimeters distal from lateral epicondyle where nn goes under the supinator muscle Paresthesia & weakness rare…If complaint, usually secondary to pain Tenderness to palpation Provoke pain with resisted 3rd finger extension (with elbow in extension) while patient extends their wrist & fingers Pain & symptoms may be relieved by passive flexion of wrist. Diagnostic studies: Electrodiagnostic studies: usually negative MD’s may inject lidocaine into the radial tunnel to see if that alleviate the symptoms, if so, than RTS was diagnosis, if not maybe it was tennis elbow.

Posterior tennis elbow aka: Triceps tendinosis, Boxer’s elbow Souza Etiology: Rapid extension leads to straining of the tendon RARE condition: tendonitis @ olecranon tender where touches olecranon 83 Ortho Lecture Notes Combined Rapid extension will irritate: boxing tennis testing & Resisted elbow extension Risk Factors: Activities that require rapid or repetitive elbow extension Throwing Punching Serving motions Weightlifting Clinical Presentation Refer to Souza this is supplemental Key test: Resisted elbow extension with elbow in flexion & the forearm fully supinated Joint play movements should be full and painless. Tenderness may be palpated over the insertion of the triceps tendon into the olecranon. Visual inspection is usually normal Treatment: Refer to Souza Counterforce bracing & taping might be useful Soft tissue Rest US, IFC Strengthening concentrating on total arm strength & balance; consider eccentric focus Visually appears normal REST Posterior Impingement Syndrome Refer to Souza – this is supplemental Repetitive forced extension: Boxers, Javelin thrower, trauma, contact sports, MMA Etiology: Caused by repetitive forced elbow extension OVERUSE o deceleration/follow through phase of throw may hyperextend elbow o repetitive punching, forcing the elbow into hyperextension. Trauma - in contact sports o collision to the back of the elbow, o forcing the elbow to bend in the wrong direction. Risk Factors Throwing athlete (pitchers, javelin throwers, cricketers) Boxers &/or other martial arts Clinical Presentation gradual increase in posterior elbow pain swelling & stiffness. Palpatory tenderness will be noted in the posterior portion of the elbow. Crepitus noted with active & passive ROM may be fragments of bone from trauma 3 phases of development o Pain after activity 84 Ortho Lecture Notes Combined o Pain w/activity o Pain all the time ROM changes – loss of extension & provocation o Crepitus, locking, catching ? o Crepitus may be noted with active and passive ROM Valgus extension overload test: may reveal valgus instability or medial and posteromedial pain Diagnostic Studies: X-rays may not adequately diagnosis the condition unless there are spurs or loose bodies in the back of the elbow. Can only see if spur or fragment Ultrasound or MRI better diagnostic tools. Treatment Rest, Rehab Work on Shoulder & Wrist always w/elbow injury Tape, brace, Adjust Nursemaid’s Elbow Refer to Souza – this is supplemental Etiology: Axial traction & falls are most common causes. Epidemiology 2-4 years old most common can occur from infancy to about 7 years old females > males tends toward non-dominant arm but can be either Clinical Presentation Anxious child, overly protective of elbow The forearm is usually flexed 15-20 degrees at the elbow, & the forearm is partially pronated. Often, the weight of the affected arm is supported with the other hand Tenderness or malposition at the head of the radius may be present. The patient resists supination/pronation as well as flexion/extension of the forearm Dislocates from annular ligament Diagnostic studies: Ultrasonography has been used as a noninvasive modality to assess for annular ligamentous injury & displacement of the radial head from the capitellum. It has also been used to assess progress of treatment for patients with recurrent subluxations. Circulation normal MM strength normal ROM restricted by pain Treatment: 1. Put pressure on head of radius 2. Grab wrist & supinate while flexing the elbow and putting pressure on the radial head 3. Should pop right in 85 Ortho Lecture Notes Combined Little League Elbow Refer to Souza – this is supplemental Epidemiology: Overhead throwers under 16 years of age. May have hx of other issues, injury, change in patter Clinical Presentation Pain is most commonly localized to the medial epicondyle, although patients may also present with lateral or posterior elbow pain. Medial elbow pain o During palpation o During cocking and/or acceleration phases of throwing is typical. Pain during the deceleration phase is more likely to be associated with posterior elbow injuries. Past history of injuries such as shoulder, back, or knee injuries that can easily alter the biomechanics of throwing may place the elbow at increased risk for overuse injuries. Treatment Rest Tape Panner’s disease *rare, essentially osteochondritis dessicans of the elbow Refer to Souza Epidemiology: Athletic overhead throwers age 5-10. Male>Female Bone appears flattened out at the trochlea of the elbow Treatment: Rest, ice, anti-inflammatory Prognosis good if they rest and treat well Case: 14 yo BM presents to office complaining of posterior elbow pain DDX & why not Post impingement – ROM would be limited in extension, would have crepitus, swelling Olecranon bursitis – not b/c there’s no swelling and full ROM Post tennis elbow – Best Dx Little league elbow - wrong phase of throwing, not pain in stress test Panners – too old Exam: Palpate RROM Findings: Visual normal ROM normal RROM extension hurt in supination No locking or creptiis 86 Ortho Lecture Notes Combined Wrist & Hands Learning Objectives: 1.

In Tendon Sheath Etiology: Unknown, possible: Direct injury. Overuse or repetitive motions, such as those you do at work. Can be on foot Epidemiology: F>M 20-40s, can occur at any age however Most common soft tissue tumor of the hand & wrist Most common occurs on the dorsum (lateral) of wrist (50-70%) Volar of wrist is the next most common site (18-20%) Often seen in Gymnasts who repetitively apply stress to wrist. Clinical Presentation Usually develop over a period of months although occasional will be sudden. Usually solitary, firm, smooth, round & fluctuant Typically asymptomatic o Possible achiness &/or paresthesia from mass effect or compression o maybe present (ex. median nerve or radial nerve) Mass that fluctuate in size (from 1-3cm) Usually soft but larger ones may be firm, may be moveable ROM may provoke Possible muscle weakness- if the cyst is connected to a tendon (b/c on mm tendons) Can be transilluminated – help differentiate from solid masses used do see if fluid filled Diagnostic Studies: Typically not required unless diagnosis is in question use to r/o bone lesion X-ray - used to rule out other bone or joint abnormalities Ultrasound - Helpful to demonstrate smooth cystic walls that may be separated MRI - not often done, used to differentiate malignant bone lesion from cystic structures Needle Biopsy Treatment Assess biomechanics to guide treatment o Observation if asymptomatic although may want to assess biomechanics of wrist/forearm & do work to optimize Activity modification if you believe cause is due to a repetitive motion Aspiration followed by steroid injection o ~50% recur within yr Surgical removal (85-95% success rate) Bible therapy o Rupture cyst by sharp blow with a book or compression – o "bible therapy" – low success rate & high rate of recurrence 89 Ortho Lecture Notes Combined Triangular Fibrocartilage Tears (S63.599A) Type 1: TRAUMA Type 2: Degenerative, Repetitive use, likely Positive ulnar variance 3 parts to TFCC: Etiology: Most common = wrist hyperextension & pronation o Type I – Traumatic Tears Fall on extended wrist, esp when wrist is pronated Sudden excessive pronation or supination o e.g. Power drill injuries can also cause triangular fibrocartilage complex rupture when the drill binds & the wrist rotates instead of the drill bit) may lead to TFCC disruption or peripheral tears (DRUJ instability) Distraction forces applied to the volar forearm & wrist Radial fractures Type II – Degenerative (Chronic) Tears A degenerative tear may occur as a result of ‘ulnocarpal impaction syndrome’ when the end of the ulnar chronically ‘impacts’ on the TFC & triquetrum & lunate. A + ulnar variance increases the risk. Repetitive loading with heaving lifting & ulnar deviation or ulnar loading (racquet sports Epidemiology: Gymnasts, skateboarders Workers who do a lot of pulling or twisting with hands (lifting heavy tools) Participate in racquet/bat/club sports Degeneration starts in 3rd decade & by 5th decade it is rare to have normal TFCC ) Clinical Presentation Dull aching sensation on ulnar side of wrist radiating to dorsal wrist Grip weakness with possible associated clicking esp w/pronation & supination activities (turning doorknob, key, can opener) Pain increases with ulnar deviation A feeling of instability, like the wrist is going to give out on them. Tenderness @ dorsal depression distal to ulnar head, localized around the ulnar styloid or between the triquetrum & the ulnar styloid May have sag ROM may be full or limited – possible clicking with active / passive ROM Pain with forced forearm pronation & supination or pain with gripping & ulnar deviation; Ulnar carpal sag may be visualized (+) Triangular fibrocartilage compression test Extensor carpi ulnaris tendon may be subluxated (ECU tendon sheath floor connects broadly to the TFCC) – may be felt during extension Piano key sign - a prominent & ballottable distal ulna with full pronation of the forearm Diminished grip strength DRUJ Compression (Grind) test should be performed to help r/o concurrent injury – compress radius & ulnar together & then pronate/supinate; + test increase in pain DRUJ Ballottement test – hold both the distal radius & ulna & apply a shear (A-P, P-A)first to the one & then the other; + increase translation 90 Ortho Lecture Notes Combined Squeeze Ulnar & Radius hurts when twist Diagnostic Studies: X-ray - may illustrate the presence of a fracture, + ulnar variance, possible DJD MRI with contrast is best - demonstrates a 0.8 sensitivity & 0.7 specificity (Iordache SD, Rowan R, Garvin GJ, Osman S, Grewal R, Faber KJ. Prevalence of triangular fibrocartilage complex abnormalities on MRI scans of asymptomatic wrists. J Hand Surg Am. 2012 Jan. 37(1):98-103.) Arthrogram – diagnostic utility is in question Arthroscopy – diagnostic standard Treatment: Conservative management tends to be ineffective for chronic (>6 mo.) & symptomatic injuries. If chronic, tends to be ineffective Immobilization o Degenerative tears immobilize in short arm cast in slight flexion & ulnar deviation for 3-6 wks; o Traumatic tears immobilize in a long arm cast for 4-6 wks NSAIDs during immobilization Possible steroid injections Removable wrist splint & rehabilitation after initial immobilization o AROM & Assisted AROM exercises – wrist (flexion / extension, ulnar / radial deviation), fingers/thumb (flexion / extension), forearm (pronation / supination), elbow (flexion/extension). Note: initially may need to avoid ulnar deviation & compression for a period of time after splinting. o Tendon Glide exercises – differentiate wrist from finger tendons, increase their movement o Functional exercises – fist formation, opposition & grip o Massage – reduce swelling & scarring/adhesion formation o Passive Accessory Movement Glides – particularly wrist (AP, PA & Med/Lat) Surgery – o Depending on size & location of tear (if tear is in center of cartilage which is the avascular zone) surgery may be the treatment of choice o If pt has + ulnar variance surgery is better option o Pt not responding to immobilization Dupuytren’s Contracture M72.0 Etiology: Unknown Pronounced genetic predisposition Possible trauma Pathology Fibroblastic proliferation, disorderly collagen type II, fascial thickening.

Injecting a type of enzyme into the taut cord in the palm can soften & weaken it — o allowing the doctor to later manipulate the hand in an attempt to break the cord & straighten fingers. Fairly high rate of re-occurrence but procedure can be repeated. Needling to break cords – This technique uses a needle, inserted through your skin, to puncture & "break" the cord of tissue that's contracting a finger. o Contractures often recur but the procedure can be repeated. o Main advantages of the needling technique are that there is no incision, it can be done on several fingers at the same time, & usually very little physical therapy is needed afterward. o Main disadvantage is that it cannot be used in some locations in the finger, because it could damage a nerve or tendon. Surgery – various forms of fasciectomy or fasciotomy (Because it is a genetic disorder – the contractures may return post-surgery) – o Main advantage to surgery is that it results in a more complete joint release than that provided by the needle or enzyme methods. o Main disadvantages = physical therapy is usually needed after surgery, & the recovery time can be longer. Complex Regional Pain Syndrome (CRPS) G90.50 Definition: Painful array of conditions; continuing (spontaneous or evoked) regional pain disproportionate to usual course of any known trauma or other lesion. Pain is regional (not in a specific nerve territory or dermatome) o usually distal predominance of abnormal sensory, motor, sudomotor, vasomotor, trophic findings. The syndrome shows variable progression over time Major involvement of SYMPATHETIC NERVOUS SYTEM Synonyms: Have been & may still be used on boards Reflex Sympathetic Dystrophy (RSD) Shoulder-Hand Syndrome Causalgia Sudeck’s atrophy Pathology: Both etiology & pathogenesis are unknown. Proposed theories: *GROSSLY SWOLLEN HAND* Direct nerve injury release of inflammatory mediators & pain-producing peptides by peripheral nerves Central sensitization - increased nociceptive afferent activity due to: o peripheral noxious stimuli, o tissue damage, or nerve injury o increases synaptic transmission at somatosensory neurons in dorsal horn of spinal cord Sympathetic overactivity due to catecholamine hypersensitivity & may involve reflex arc formation after inciting incident Genetic factor - significantly increased HLA-DQ1 among patients affected by CRPS type I 93 Ortho Lecture Notes Combined Type I – aka RSD – no evidence injury/peripheral nerve injury 90% of the pts have this form= MC Type II – aka causalgia – secondary peripheral N injury “Warm” CRPS – increased skin temp @ onset of Sx – suggests inflammatory type “Cold” CRPS – decreased skin temperature at onset of symptoms Epidemiology: F >M (highest postmenopausal women) 55-75 yrs Risk Factors: Trauma – fractures, crush injuries, sprains, surgery Immobilization following trauma ACEI use Stroke Clinical Presentation STAMP – Symptoms beyond initial site of trauma Trophic changes Autonomic changes Motor Pain Sensory – hyper, distal Main symptoms: pain, sensory changes, motor impairments, autonomic symptoms, trophic limb change ONSET: approx. 4-6 wks after inciting event Symptoms go beyond the initial site of trauma & may actually spread to other limbs Pain - Most debilitating symptom o Out of proportion to the injury o Burning, stinging, tearing sensation deep in limb (may be superficial) o Usually continuous but may be paroxysmal o Exacerbated by movement, contact, stress, temperature change Sensory - Hyperalgesia, Allodynia, Hypesthesia o Usually distal – possibly follows glove/stocking distribution Motor - Limited by pain, edema, contracture o May develop: tremors, myoclonus &/or dystonic postures Autonomic differences o Skin temp o Skin color o Sweat o Edema Trophic changes o Hair growth o Increased/decreased nail growth, yet skin atrophy o Contracture/fibrosis of joints & fascia 94 Ortho Lecture Notes Combined Stages: In most cases, CRPS has three stages. o However, CRPS does not always follow this pattern. o Some people develop severe symptoms almost right away. o Others stay in the first stage or can skip phases. Early identification has best prognosis (within 1st 6 months, but IDEALLY w/in 1st 3 months) Stage 1 (lasts 1 - 3 months): The first 2-stages are considered reversible, can go into remission. o Severe burning, throbbing, aching pain which doesn’t follow a known nerve distribution o Sensitivity to touch or cold o Localized edema o Altered skin color - slowly becomes blotchy, purple, pale, or red; thin & shiny o Sweating o Faster growth of nails & hair o Muscle spasms & joint pain o Radiographs are typically negative although possible to have isolated demineralization Stage 2 (lasts 3 - 6 months): “Dystrophic Stage” o Progression of soft tissue edema o Thickening of skin, ligaments, capsules (stiffness) o Muscle wasting, atrophy, stiffness o Brawny skin development o Worsening Pain o Slower hair growth o Osteopenia Stage 3 (irreversible changes can be seen): Atrophic stage unlimited amount of time Permanent changes start to persist o Limited movement in limb because of tightened muscles & tendons (contractures) o Marked atrophy o Entire limb pain o Waxy, trophic skin changes o Brittle, ridged nails o Condition may spread to other limbs at this stage o Severe Osteopenia Budapest consensus criteria for the clinical diagnosis of CRPS A: Pt has continuing pain; disproportionate to MOI B: Pt has at least one sign in two or more categories categories C: Pt reports at least one symptom in three or more categories D: No other diagnosis can better explains signs and symptoms Categories- STAMP Signs – see or feel a problem Symptoms – patient reports a problem (Hardin, Bruehl. (2007) Proposed New Diagnostic Criteria for Complex Regional. Pain Syndrome, PAIN MEDICINE, 8(4):1-6) 1. Continuing pain, which is disproportionate to any inciting event 2. Must report at least one symptom in three of the four following categories: Sensory: Reports hyperesthesia and/or allodynia Vasomotor: Reports skin temperature or color change or asymmetry Sudomotor/Edema: Reports of edema and/or sweating changes or asymmetry Motor/Trophic: Reports decreased range of motion, motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin) 3. Must display at least one sign at time of evaluation in two or more of the following categories: 95 Ortho Lecture Notes Combined Sensory: Evidence of hyperalgesia (to pinprick) and/or allodynia (to light touch and/or temperature sensation and/or deep somatic pressure and/or joint movement) Vasomotor: Evidence of temperature asymmetry (>1°C) and/or skin color changes and/or asymmetry Sudomotor/Edema: Evidence of edema and/or sweating changes and/or sweating asymmetry Motor/Trophic: Evidence of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin) 4. There is no other diagnosis that better explains the signs & symptoms Diagnostic Studies: Not very effective in Dx Infrared Thermography — to detect changes in body temperature that are common in CRPS. A colorcoded "thermogram" of a person in pain often shows an altered blood supply to the painful area, appearing as a different shade (abnormally pale or violet) than the surrounding areas of the corresponding part on the other side of the body. An abnormal thermogram in a patient who complains of pain may lead to a diagnosis of CRPS. Radiography – may show spotty or localized demineralization – not diagnostic MRI - not very useful in diagnosis of CRPS Bone Scan – there is active reabsorption of bone so increase uptake- may be helpful in the diagnosis in 1st 5 mos; negative scan may help r/o CRPS but doesn’t rule out. Autonomic Testing – helpful but not practical as routine tests o Resting sweat output (RSO) = good predictor of CRPS o Resting skin temperature (RST) – useful in the diagnosis but not practical to perform it requires serial skin temperature readings at 1 minutes intervals for 5-8 hrs o Quantitative Sudomotor Axon Reflex Test (QSART) – measures heat output in response to iontophoresis cholinergic challenge (such as acetylcholine) Treatment: Occupational/Physical Therapy - Main form of therapy for condition. Most common o Increasing exercise program to help preserve or restore mobility & function to the affected limb. o Aerobic conditioning is very important to improve coping ability, sleep, & pain control. o Pool therapy may be used to help patients with trouble weight bearing. o Graded motor imagery (esp preceding mirror visual feedback) – patient imagines moving painful limb into a position seen in a photograph of a limb, then followed by moving both limbs into the position while watching unaffected limb in a mirror that obscures the affected limb o Mirror Visual Feedback – so see a well limb o Postural control & gait retraining o Vocational support o Desensitization program – rubbing affected limb gently, increasing weight bearing, stretching, hot or cold baths – progress to isometric exercise when patient can tolerate touch stimulus, progress to isotonic & ADLs activities next Psychotherapy - depression, anxiety, or post-traumatic stress disorder. o A psychologist or psychiatrist may be able to improve coping ability & motivation as well as detect & address any substance dependency issues. o Imagine moving the limb 96 Ortho Lecture Notes Combined Refer to Pain management Nerve Blocks - Many patients experience significant relief from nerve blocks,. By relieving pain, blocks can enable more effective therapy, improve mood, & improve level of activity. Medications - may include: NSAIDs, topical analgesics (lidocaine or capsaicin), anti-seizure drugs (decrease neuropathic pain), antidepressants (for depression & neuropathic pain), corticosteroids, muscle relaxants, Bisphosphonates/Calcitonin, opioids, & sleeping medications. Spinal cord stimulators Pain pumps Epidurals - clonidine Trigger/tender point injections Surgery - If the CRPS is from a compressed nerve, such as with carpal tunnel syndrome, then surgery to release pressure on the nerve may be needed (e.g., carpal tunnel release). Rarely, an operation known as sympathectomy is used to divide the sympathetic nerves in patients who are helped by nerve blocks, & its use is controversial. Prognosis: Favorable prognosis if treatment is begun early, ideally within 3 months of the first symptoms. Poor to Guarded - if treatment is delayed the disorder can quickly spread to the entire limb & changes in bone & muscle may become irreversible. o In 50% of cases, pain persists longer than 6 months & sometimes for years or indefinitely 25-30% = have full recovery Younger the patient the higher chance of complete recovery (NIH) Prevention: Taking Vit C after trauma - Studies have shown that people who take daily vitamin C supplements after injury have a lower risk of CRPS compared with those who don't. Early movement after a stroke - Some research suggests that people who get out of bed & walk around soon after a stroke lower their risk Early mobilization after limb injury 97 Ortho Lecture Notes Combined Cherialgia paresthetica Radial N Aka: Wartenberg Syndrome Aka Superfical radial neuropathy Aka Handcuff neuropathy G56.30 Etiology: Compression of the sensory branch in wrist or distal forearm (handcuffs, watch, casts). o Direct trauma to the nerve o Fractures or lacerations frequently completely disrupt the nerve o Damaged via surgical of De Quervain's tenosynovitis Clinical Presentation - Rare condition Paresthesia/pain/dysethesia in superficial radial nerve distribution Possible sensory changes in that distribution Provocation w/ulnar deviation (e.g., similar to Finkelstein’s) Tinel’s over the SRN may also provoke NO MOTOR involvement Inspection: may see tight watch Palpation: possibly tender N ROM – better w/extension & radial deviation, worse w/ flexion & ulnar deviation Treatment: usually settles w/ conservative therapy; may take up to 2 months o NSAIDs o Avoidance of external compression. o Soft tissue modalities o CMT o Splint the wrist in extension & radial deviation if indicated – Decompress N Medical Management: Possible steroid injection or surgical decompression Complete anaesthesia suggests complete severance of the radial nerve & should prompt urgent surgical referral 98 Ortho Lecture Notes Combined Intersection syndrome -Aka- Peritendinitis crepitans Oarsmen's wrist Subcutaneous perimyositis Squeaker's wrist Adventitial bursitis Crossover syndrome Supplemental to Souza Etiology: overuse direct trauma to the second extensor compartment Epidemiology: Weightlifters, rowers, & other athletes are particularly prone to this condition Wait staff Extensors Clinical Presentation dorsoradial wrist or forearm pain Pain can spread down to the thumb or up edge of the forearm.

Complication: As a consequence to that type of injury (force to the sternum) patient may also experience a myocardial contusion o pericardial sac fills up with fluid not allowing the heart to beat Management: REFER OUT Rest. Observe & monitor the patient for cardiac a/dysrhythmias. Chiro should probably refer the patient Herpes Zoster (Shingles) (B02.9 zoster without complications) Etiology: Patient has a localized reactivation of Varicella-Zoster virus (virus that causes chickenpox) Infection in the ganglia & nerve trunk Epidemiology: 32% US experience Zoster during lifetime 1 million cases annually Incidence rates increase with age Risk Factors: Those who have impaired cellular immunity: a. Pregnancy b. Malignancies c. Organ transplant patient d. Chemotherapy patients e. Patients with HIV f. Patients on steroids g. Pts with autoimmune diseases Clinical Characteristics: Preherpetic neuralgia Radicular pain, pruritis, paresthesias appear 1 week before appearance of 1st skin lesions Can last 100+ days (described by Cluff & Rowbotham, 1998) Vesicular or bullous eruption Worse skin eruption = the worse pain & longer duration Limited to a dermatomal distribution. Prior to eruption may have a pre-eruptive tenderness or hyperesthesia throughout the involved dermatome. Differentiating this condition may be difficult, especially if the rash is not present. The pain may simulate pleurisy, myocardial infarction, disc disease, abdominal disease. Prodrome: Some patients experience symptoms: fever, malaise, headache. Localized lymphadenopathy Course: typically lasts 3-6 weeks In elderly or debilitated it may last longer. Subsequent outbreaks are common *commonly recur 111 Ortho Lecture Notes Combined Diagnosis: Definitive Dx is made via isolation of the Varcella-Zoster Virus (VZV) in blood or CSF Clinical diagnosis is via history & presence of rash Treatment: Manipulation/adjusting Mostly nutritional: Lysine supplementation Vitamins to help immune system Analgesics – may help for patients whose pain severity is mild to moderate Suppression of inflammation & infection (Burow’s solution or Betadine) Acyclovir, famcyclovir or valacyclovir = anti-viral agents Dosage = 800 mg, 5 times/day for 7-10 days Shown to decrease duration of rash & severity of pain Must be given within 72 hours of onset of the rash to be effective Corticosteroids – in conjunction with anti-virals may help pain Calamine lotions – control pain & reduce pruritus Capsaicin cream – pain control once rash has crusted over Prevention of post-herpetic neuralgia = use of steroids (questionable efficacy), Capsaicin cream, tricyclic antidepressants & anti-convulsants (gabapentin) Don’t scratch & wash hands frequently – the patient is contagious (spread chicken pox not shingles) Prevention Zoster vaccine should be considered for all immune compromised individuals (it is a live attenuated virus so in some patients it may actually be considered contraindicated ) & individuals who are 60+ yrs of age. Snapping Scapula Syndrome aka Scapulothoracic Syndrome (M75.80 – other shoulder lesion, unspecified) Definition: Snapping scapula syndrome = rare cause of shoulder/posterior chest wall pain. Scap hits ribs Pathology: Convex chest wall normally is congruent & allows smooth gliding motion to the concave, deep surface of the scapula & interposed serratus anterior & subscapularis muscles. Inferior, medial, & superior borders are not well cushioned & may rub against the chest wall causing grating or snapping noises. Causes can be divided into bony & soft tissue problems. Bony Soft tissue Abnormal curvature Subscapular bursitis Omovertebral bone (bone from shoulder to vertebra) Interstitial myofibrosis Tubercle of luschka Atrophy of subscapularis Osteosarcoma Chondrosarcoma Clinical Presentations Grating, grinding, popping, snapping sensation as the scapula glides over the ribs Pain is possible over the area & in shoulder especially with overhead activities Possible scapular malposition Possible atrophy of subscapularis Tenderness w/a bursitis 112 Ortho Lecture Notes Combined Sound heard/felt during ROM will hear or feel Altered scapulohumeral rhythm – this may contribute to shoulder dysfunction/pain Treatment: Exercise to strengthen subscapularis & other muscles as indicated (scapular stabilizers) Anti-inflammatory medication &/or diet/supplements/homeopathics if subscapular bursitis is present (if bursitis especially) Possible cortisone injections Surgery: o bony anomalies/tumors or not responding to conservative care – o remove anomalie/etc o resection of a small piece of the top medial border of the scapula. VISCERAL CAUSES OF CHEST WALL SYNDROME Organs that cause left-sided chest wall pain = Heart, lung, pancreas, kidney, spleen, diaphragm Organs that cause right-sided chest wall pain = Lung, liver, kidney, diaphragm, gall bladder* *GB refers to inferior angle of the right scapula Pneumothorax (J93.9 – unspecified) Definition: An accumulation of air or gas in the pleural cavity causing the lung to collapse Types: Traumatic - wound to chest cavity leads to lung collapse (most common is rib fracture) Spontaneous - etiology unknown may be secondary to some other systemic condition. A spontaneous pneumothorax occurs without chest trauma & is usually due to the rupture of a small cyst on the lung surface. Such cysts may occur without any associated lung disease, or they can develop due to a variety of underlying lung disorders, emphysema being the most common. *Either can result in a collapsed lung Epidemiology: Spontaneous pneumothorax occurs in tall, thin males between the ages of 20 & 40. Men > Females 6:1 Usually occurs at rest or sleep. There is a higher incidence in smokers. o Male smokers have 22 times the likelihood of spontaneous pneumothorax compared to nonsmoking males. Spontaneous pneumothorax are more likely to occur in the fall or winter months. o and in tall, thin, smoking males Clinical Presentations Dypsnea (SOB) Chest wall/shoulder pain Dizziness Asymmetrical excursion due to atelactasis Tracheal or mediastinal shift away from collapsed lung, due to air filling lungs 113 Ortho Lecture Notes Combined Decrease in fremitus, hyper-resonance, & diminished or no breath sounds. Diagnostic studies: Plain films no lung markings (opacity) will be seen in the lung field, it will be black. Treatment: Emergent referral If left untreated, HIGH recurrence rates of a spontaneous pneumothorax. o Same side recurrence rates are as high as: 30% at six months up to 50% @ two years. The objective of treatment is to remove the air from the pleural space, o allow lung to re-expand. Small pneumothoraces may resolve on their own. Gastroesophageal Reflux Disease (GERD) (K21.0 GERD w/esophagitis, K21.9 GERD w/o esophagitis ) Definition: Inflammation of esophagus Sphincter not working & acid burns esophagus usually resulting from reflux of low pH gastric juices Contents (acidic) that irritates the wall of the distal esophagus Epidemiology 33% to 40% of adults at some point in their lives 10% of United States population experiences GERD symptoms daily 50% of pregnant women will experience GERD Risk Factors Obesity & family history may be risk factors for GERD. Ingesting large quantities of caffeinated beverages Foods Pathogenesis Sphincter tone = transient relaxation of the lower esophageal sphincter (LES) - dietary factors, which diminish the tone are: fat, whole milk, orange juice, tomatoes, anti-flatulent drugs, chocolate, & high doses of ethanol. Factors that increase tone: protein, carbohydrates, nonfat milk, & low doses of ethanol Prolonged exposure to o gastric contents (acidic in nature) – o Acidic foods are citrus juices, tomatoes, & coffee. o Agents that diminish acidity: oral antacids, bicarbonate in saliva & anticholinergic agents. Large hiatal hernia Esophageal motility disorders Delayed gastric emptying Clinical Presentation Heartburn lower retrosternal region, spreads up into chest, back, interscapular region, throat, jaw. Usually postprandial pain *after a meal 114 Ortho Lecture Notes Combined Provoked w/ingesting cold fluids, or when the patient bends over or when lying down Regurgitation may or may not occur Exam is typically negative, possible epigastric tenderness Symptom scale for diagnosing GERD: Calculate points: daily (3) at least once weekly (2) at least once monthly (1) never (0) heartburn regurgitation points: yes (1) no (0) dysphagia dysphonia asthma points: permanent (2) occasional (1) never (0) chest pain nocturnal cough cut-off of 3 points correlates with GERD Diagnostic Studies: Endoscopy – study of choice EGD - Esophagogastroduodenoscopy Manometry – measure strength of motility in the gut Management - Includes life style modifications Stop smoking Lose excess weight Eat small meals Reduce caffeine, chocolate, fatty foods, alcohol, onions, peppermint & spearmint Elevate head of bed 6”- 9” Avoid tight fitting garments Do not eat 2-3 hrs prior to going to bed Antacids, H2 receptor antagonists (for example: Tagamet), PPI CMT Anti-reflux surgery (hernia reduction, etc) HIATAL HERNIA (K44.9) Definition: Herniation of a portion of stomach into the thoracic cavity through diaphragmatic esophageal hiatus Pathology Thought from imbalance between normal pulling forces of the esophagus through the diaphragmatic hiatus during swallowing & supporting structures maintaining normal esophagogastric junction position w/repetitive stretching that results in rupture or stretching of the phrenoesophageal membrane Epidemiology Most commonly (50%) found in 50+ years Women > Men 4:1 115 Ortho Lecture Notes Combined Types: Sliding (90% of cases) – widening of the esophageal hiatus MOST COMMON Paraesophageal – tearing of phrenoesophageal membrane Clinical Manifestations Asymptomatic Reflux Respiratory symptoms Heartburn Coughing/hiccups increase abdominal pressure, so increase risk of GERD Abdominal exam is negative Diagnostic studies Plain film Endoscopy Management: No treatment may be required Manual reduction of the hernia SMT dietary changes antacids/H2 blockers/PPIs, possible surgery Teach self-massage Complication: Incarceration & strangulation o If pressure, may choke out a part of stomach ANGINA (I20.9 - unspecified) Mechanism: Ischemia to the cardiac muscle Clinical Manifestations Stable angina – provoked with excitement/exertion, relieved by rest. Usually caused by a fixed coronary artery obstruction secondary to atherosclerosis. Unstable angina (Prinzmetal) – can occur at any time, rest doesn’t change it, Usually caused by coronary artery spasms with or without superimposed coronary artery disease. Chest pain: short duration from 30 seconds to around 30 minutes pain = substernal heaviness, pressure or squeezing sensation sometimes described more as discomfort that can radiate. Often explained as similar pain as intestinal gas or dysphasia. Dyspnea, diaphoresis are possible irregular heart beat or bradycardia, hypotension (shock) or hypertension (+/-) vitals may be normal Heart exam may not be helpful Management If undiagnosed – emergent ER 116 Ortho Lecture Notes Combined If diagnosed – o encourage patient to take their medication (nitro) – if patient doesn’t respond after the first dose call 911; the patient can take 1 table at 5 minute intervals up to 3 tablets Low Back Pain Objectives Describe the etiology, pathogenesis, risk factors, signs/symptoms, diagnostic studies associated with the conditions discussed in Orthopedics I.

Lumbar Canal Stenosis (Central stenosis M48.06, Lateral Canal M99.63) Definitions: Stenosis = narrowing of a tube or canal o central canal, lateral recess or neural foramen. Central & sometimes lateral canal stenosis leads to neurogenic claudication. Lateral recess or foraminal zone stenosis leads to radiculopathy. Neurogenic claudication = direct compression of the cord and/or cauda equina which produces vague symptoms/signs of pain (cramping, aching), radicular pain, paresthesias, heaviness, sensory changes, paresis, paralysis, &/or etc. direct cord compression Arterial claudication = claudication symptoms that are due to inadequate blood supply to an area Lateral canal stenosis = radicular sx Central conal stenosis = neurogenic signs Zones of lateral canal stenosis “compression” o Lateral Recess - It is a groove that is bordered laterally by the pedicles, posterior by the superior articular facet & anterior by the posterior lateral surface of the vertebral body & the disc. Each exiting nerve root traverses through this part of the canal. This is the most common site of lateral canal stenosis. SUPRA-Articular Facet o Foraminal Zone - this zone is bordered by the lateral margin of the pedicle. o Extraforaminal Zone - This is entrapment of a root outside IVF. o It most commonly occurs only at the L5/S1 level. o Entrapment o Lumbarization or sacralization 117 Ortho Lecture Notes Combined Epidemiology: AGE Neurogenic claudication typical onset >60 yrs “Shopping Cart Sign” Incidence & prevalence of symptomatic lumbar spinal stenosis unknown Estimated prevalence of radiographic lumbar stenosis in asymptomatic adults > 55 years old o 21%-30% for moderate stenosis already have o 6%-7% for severe stenosis About 30% of adults may have radiographic spinal stenosis L4-L5 most common level Etiology: The most common cause of lumbar spinal stenosis is age-related changes of the spine (90-95%). These changes include thickening of soft tissues & a gradual deterioration of spinal discs & joints that connect the spine's vertebrae. Any of these conditions can narrow the spinal canal. Acquired *compression, direct or indirect -or- ischemia are main causes o Most common (90-95%) degenerative changes (osteoarthritis/spondylosis) in the facets & discs. Hypertrophy/osteophytes of the superior articular facet in an anterior direction may narrow the lateral canal hypertrophy /osteophytes of the inferior articular facet on a medial direction may narrow the central canal hypertrophy of the ligamentum flavum or anything compressing into the area o Disc herniation o Instability – arthritic changes to the facets & disc may lead to vertebral subluxation o Skeletal diseases Paget's disease, ankylosing spondylitis, rheumatoid arthritis, & diffuse idiopathic skeletal hyperostosis, may soften the spinal bones or cause too much bone to grow. Tumors o Traumatic or post-operative Spinal fracture Fibrosis-which is in excess, ropy tissue much like scar tissue-from having spine surgery in the past.

Therefore certain movements (flex/ext & rotation) of the body may result in an intermittent narrowing of the lateral canal & symptoms/signs. Pt may respond to manipulation immediately but then they need stabilization. o If instability, facet may move not space o IF adjusted, may get better really fast o Next stabilize the joint Fixed Lateral Canal Stenosis (FLCS) - Osteophytic & hypertrophic changes of the facets have occurred in order to stabilize the segment therefore the stenosis is permanent & symptoms/signs are constant. o Permanent changes Diagnostic Studies: Plain film - decrease disc height, osteophytes, sclerosis, decrease IVF height, hypertrophy facets, transitional vertebra o “Eisenstein's Lines” Measurement: Verbiest & Eisenstein have determined that the normal distance of the central spinal canal is between 15-23 mm. The canal is measured from a perpendicular line drawn through the posterior border of the vertebral body to the perpendicular line drawn through the anterior aspect of the superior facet. Minimum normal sagittal diameter is approximately 15 mm. 120 Ortho Lecture Notes Combined Absolute stenosis - the diameter is <10 mm Relative stenosis - the diameter is between 10-12 mm Measurement between 12-13mm is considered below normal. MRI shows the soft parts of the spine better than the bones. With spinal stenosis, the position of the spinal nerves & evaluation of the space available for them is easier to see on an MRI. Disc problems show up better on MRIs than on CT scans. MRI may also show tumors, infections, & other disorders. (Sensitivity 80-90%; Specificity 95%) o recess < 3mm = stenosis lateral canal o recess between 3-5mm highly suggestive of stenosis o recess > 5mm = normal ON Lateral canal (above dx) CTScan - Similar to MRI slightly better at seeing bones than soft tissue. (Sensitivity 75-85%; Specificity 80%) Myelography - Look for narrowing of the canal, not commonly ordered due to utilization of the MRI/CT technology & because it is an invasive technique. (Sensitivity 77%; Specificity 72%) Electrodiagnostics – overall utility is limited , sometimes done to see if you might have problems other than or in addition to lumbar spinal stenosis o NCV/SSEP - Look for signs of diminished nerve conduction o EMG - Will show diminished muscle activity. (good instrument to determine which root level is involved.) Criteria for Referral: Unremitting pain/disability Progressive neurological deficit (LMNL, UMNL, Cauda equina) Management: Following based on the treatment recommendations of the APTA (2012) for spinal stenosis only. Flexion exercises: o Combined with other interventions manual therapy, strengthening exercises, nerve mobilization procedures, progressive walking), flexion exercises can be used to reduce pain & disability in older patients (weak evidence) Manual therapy: For back-related lower extremity pain (which can be the case in spinal stenosis) manipulative procedures reduces pain & disability, while improving spine (and hip) mobility (strong evidence) Found physiotherapy had really limited evidence but suggest minimal benefits for passive physiotherapy. The effects of active physiotherapy remain unknown (Duong et al. 2010). Manipulation/Mobilization: 50% positive response to adjustments (other 50% do surgery) o Lateral canal stenosis = 50% of the patients respond favorably to chiropractic care, 50% go to surgery. o Cassidy & Mior did a study on 70 patients with lateral canal stenosis over a 5-year period & it showed 50% of the patients had good results with manipulation. Manipulation is effective with dynamic lateral canal stenosis, but it has minimal benefits with fixed. The purpose of manipulation is to: reduce minor subluxations that occur due to capsular laxity, alleviate capsular pain by inhibition to the cells, 121 Ortho Lecture Notes Combined Increase circulation & increase stability to the area of involvement. o Lumbar Spinal Stenosis (Central) = Study by Whitman demonstrated that manipulation combined with exercise have a promising effect in pts w/mild to moderate central stenosis. Flexion/Distraction; Pelvic blocking, Instrument assisted Exercise therapy: o Core stabilization o McKenzie o Williams Flexion o Flexibility (Stretching hamstrings & extensors) o Strengthening (abdominals, gluteals), o Cardiovascular (Prevent deconditioning, help weight loss) o Ergonomic training o Aquatic exercises Modalities: o Interferential o Soft tissue techniques o Lumbar Traction o Acupuncture o Lumbar bracing/support/corset (try to avoid their use) Nutrition o Promote healing - Vitamins. C, E, B, bioflavinoids, Arnica (homeopathic remedy for pain) o Anti-inflammatory diet o Possible weight loss diet (Staying at a healthy body weight, which may relieve symptoms & slow the progression of the stenosis.) Medications o NSAIDs o Epidural steroid injections - used to reduce inflammation & pain in the legs. o Opioids - Used to relieve severe back pain. Surgery o surgical decompression (removal of hypertrophied ligaments) o fusion o Facetectomy o Laminectomy o Discectomy Guidelines for recommending surgery: 1. Persistent leg pain that interferes with quality of life. 2. Failure of non-operative care to relieve symptoms over a period of at least two or three months. 3. Documented spinal stenosis confirmed on either myelogram/CT and/or MRI. 4. The patient's health allows surgery. *must be healthy enough 5. Hard neurological signs (progressive motor deficits, neurogenic bladder/bowel) Prognosis: o ~ 20% of patients w/ surgery require repeat surgery within 10 yrs. Nearly 1/3 continue to experience pain. o Dynamic lateral canal - if left untreated it will eventually progress to fixed. If treated there may be some resolution. 122 Ortho Lecture Notes Combined o Degenerative stenosis has a relatively slow benign course in most patients, although it can interfere w/ADLs. Slow, benigh arthritis o North American Spine Society (2010) reported that: in patients with mild or moderate degenerative lumbar stenosis, rapid or catastrophic neurologic decline is rare. The natural history of pts w/clinically mild to moderate degenerative stenosis can be favorable in 1/3 to ½ of pts. o Patients with stenosis may require supportive care for an extended period of time if not life long. Spondylolisthesis (Congenital spondylolisthesis Q76.2, lumbar spondylolisthesis M43.16, unspecified site M43.10, Definition: An anterior displacement of a vertebral body in relation to the segment immediately below Upper segment slides anterior Etiology & Pathogeneses: o Type 1: Congenital (dysplastic) spondylolisthesis 9-15 yrs characterized by the presence of dysplastic sacral facet joints allowing anterior translation of one vertebra relative to another. Strong association with spina bifida o F>M o This form accounts for 14%-21% of all spondylolisthesis o Strong genetic component: 1 in 3 relatives affected o If slippage occurs it is usually between the ages of 9 & 15 years. Doesn’t usually exceed 25% but if it does it may result in cauda equina syndrome o Most common level – L5/S1 o 25-35% are symptomatic o Type 2: Isthmic spondylolisthesis (Spondylolysis): “Scotty dog” A defect of the pars interarticularis o Grade 1 most commonly seen of this type. o M>F, although females are 4x more likely to have high-grade slippages o Further slippage is unusual after skeletal maturation is reached o Most common form of spondylolisthesis in pts < 50 yrs o Inuits have highest incidence; W>B o Most common level – L5/S1 Isthmic Subtypes: o Subtype A (spondylolysis): fatigue fracture of the pars. It develops as a response to cyclic flexion & extension and/or rotational loading. o Subtype B: elongation of the pars but it remains intact (no separation) o Subtype C (spondylolysis): acute pars fracture. This subtype is uncommon o Type 3: Degenerative spondylolisthesis, arthritis, Female L4, 40/50’s yrs slippage 25-30% Associated with intersegmental instability from facet arthrosis o Most common form in patients >50 yrs. o Associated with increased BMI, age & angle of lordosis in women o F>M o L4/5 most common level o 4x more common in patients w/sacralization o Slippage is generally no greater than 25-30% o The Three F's of Degenerative Spondylolisthesis = Female, Four (L4), Forty (40+) o Type 4: Traumatic spondylolisthesis, trauma to neural arch (vs. pars which is subtype C) 123 Ortho Lecture Notes Combined Acute trauma to the neural arch with the exception of the Pars; this type is extremely rare in the lumbar spine o Type 5: Pathologic spondylolisthesis, Results from damage to the posterior elements from metastasis or metabolic bone disease. o Iatrogenic: caused by doctor or medical treatment Another proposed type – post-surgical Risk Factors: SPORTS, Lineman, gymnastics Activities that require repetitive flexion & extension or hyperextension (e.g., gymnasts, football players {linemen}, weight lifting, dance, diving, figure skating) o Young 9-15 o Ligamentous laxity Clinical Presentation o May be asymptomatic o Pain, if present (~ 10% of patients with spondylolisthesis), o usually associated with a particular activity, o upright posture or hyperextension o described as a localized deep-seated, dull, achy pain o patient may have nerve root involvement manifesting with radicular pain; leg pain may be greater in patients who have a higher degree of slippage. o Sx often due to secondary Sx such as facet syndrom Nachemson, Junghan's & Schmorl - say pain is not related directly to the spondylolisthesis/ spondylolysis. It has been suggested that the fibrous union involving the spondylolytic defect may separate with repetitive motion, creating strain. The defect as well as the supraspinous ligament sprain may create localized pain. It is also thought that the symptoms may be due to a facet syndrome or sacroiliac joint syndrome. There is no definite clinical correlation between the degree of anterior displacement & the severity of symptoms. o Guarded gait or other gait disturbances (pelvic waddle due to tight hamstrings & lumbosacral kyphosis) o Phalen-Dickson sign (i.e., a knee-flexed, hip-flexed gait) may be demonstrated in cases of spondylolysis especially with spondylolisthesis. “Pimp walk” o Step defect (deformity) = If the spondylolisthesis is unstable a step defect may be positional induced o Possible hyperlordosis with lumbosacral kyphosis o Paraspinal muscle spasms/myofascitis o Tenderness o Hamstring tightness/spasm. o due to a postural reflex to try to stabilize the segment. With slippage the hamstrings readjust the anterior displace center of gravity by extending the pelvis. o ROM: possible decrease especially with degenerative; o extension may provoke the CC, complaint of stiffness o Ortho tests = +Stork test; possible +instability tests, possible +neurodynamic tests o Neuro - root signs or cauda equina syndrome w/25% slippage of L5 over the dome of the sacrum; increase in neurological involvement with degenerative spondylolisthesis Diagnosis studies: Plain film x-rays 124 Ortho Lecture Notes Combined o Forward slippage in reference to the one below – lateral view Meyerding's Classification o Grade I: 0-25% slippage o Grade II: 26-50% slippage o Grade III: 51-75% slippage o Grade IV: 76-100% slippage o Grade V: Complete slippage of vertebral body in relation to the segment below o Napolean hat sign – P-A view o Spondylolysis Spondylolisthesis: lucent defect of pars with forward slippage o Appears as “Scotty Dog” collar: anteroposterior spot film gives better view of L5-S1 disk space. OBLIQUE view o Flexion/extension views will help rule out instability. If more than 25% migration or progressive neurological involvement, refer for surgical consult. o Compression/distraction views can be used if flexion/extension views do not demonstrate instability. Natural History: The following are clinical risk factors for progression of slippage: o adolescent age o presence of symptoms o presence of generalized ligamentous laxity Progression: only 2%-3% of spondylolisthesis cases show progressive displacement. Progression of spondylolisthesis is rare for those with less than 30% slippage & rarely occurs after adolescence Management: o Rest/activity modification o Modalities for pain control (heat) o Topical analgesics (capsaicin cream) o Manipulation: Manipulate the sacroiliac joints if needed. Specific high-velocity, low-amplitude manipulations to the dysfunctional joints in side posture are the technique of choice. o A study by Mierau et al. showed that specific manipulation to the dysfunctional joints above and/or below the defect can reduce the pain & disability in chronic low back pain patients with spondylolisthesis. Prone lumbar manipulations man be harmful. o Exercise therapy: o Abdominal strengthening exercises o Lumbar stabilization exercises o Possible Williams flexion exercises although there is conflicting data (some studies suggest extension exercises) o Hamstring stretches o Weight loss (if applicable) o Bracing – controversial due to compliance, segmental motion may not be limited in a brace & deconditioning issues it isn’t warranted or effective, others say it might be beneficial with isthmic spondylo (Boston brace). Another controversy is in the type: anti-lordotic vs lordotic bracing. Antilordotic puts lumbar spine in a kyphotic position decreasing the stress on the pars; lordotic bracing loads the posterior elements which promotes healing. Only if acute o RX: NSAIDs, muscle relaxants, epidural/intrathecal injections o Surgery indications o Failure of conservative care o Progressive neurological deficit 125 Ortho Lecture Notes Combined o o o o o Cauda equine syndrome Radiographic instability with neuro signs/sx Progression of slippage Symptomatic grade 2 or higher Unremitting pain affecting ADLS Children/Adolescents Treatment: o If asymptomatic no treatment is required but risks for progression should be explained & recommend periodic follow-ups o Skeletally immature patient with slippage greater than 30%-50% is @ increased risk for progression & should undergo spinal fusion (i.e., conservative treatment has no role in their management). (Smith & Hu, 1999) o Vit D & Calcium supplementation have been suggested in children with spondylolysis o NO walker/saucer until can stand on own o If have spondy for 10+ years, then may want to limit activites, especially gymnastics Return to Play Guidelines Most athletes RTP after an appropriate period of rest (usually 90 days) & the patient is asymptomatic Step 1 (approximately one month in duration; typically begins during the period of relative rest) o To participate, the patient must demonstrate that they can perform an abdominal crunch without pain, & that they can walk without pain or limp. If so, the patient begins performing core strengthening exercises (eg, planks, bridges) daily. Low intensity aerobic activity is performed for 30 to 45 minutes daily (eg, walking or biking). Running & swimming are not permitted. o Must be able to walk w/out limp & no pain o Must be able to crunch w/out pain Step 2 (approximately one month in duration following completion of step 1; may overlap with final stages of relative rest period) o To advance to step 2, the patient must demonstrate that they no longer experience pain with hopping, normal back motions, & when performing a one leg hyperextension test. o Continue core strengthening exercises. Add weight lifting with back supported to prevent any lumbar extension beyond neutral. Include deadlifts with light weight to begin rehabilitation of hip & back extensors. Continue aerobic activity; okay to perform any such activities that do not cause pain. Patient can begin performing sport-specific drills that are low risk (eg, ground strokes in tennis, shooting drills in basketball, forward tumbling in gymnastics). o Must be able to Hop w/no discomfort Step 3 (approximately one month in duration following completion of step 2) o To advance to step 3, the patient must demonstrate pain-free running & jumping, as well as painfree back extension. o Continue core strengthening exercises. Advance weight exercises as needed for sport. Gradually & cautiously, increase the weight used for weight-lifting exercises. o Begin normal sport activities, but avoid any involving full contact. If the patient remains pain-free, the level of activity is increased weekly & more intense sport-specific drills are performed. At the end of this stage, full participation, including full contact for contact sports, is permitted to determine whether the patient can perform without pain. If not, step 3 of the recovery is extended for two weeks using exercises just short of full participation that do not cause pain, & then the athlete is reassessed. o Must be able to run & jump pain free 126 Ortho Lecture Notes Combined Chronic low back pain LBP 3 mos+ (Low back pain M54.5) Definition: Low back pain is considered to be chronic if it has been present for longer than three months. Chronic low back pain may originate from an injury, disease or stresses on different structures of the body. Leading cause of disability worldwide Etiology: Some cases of chronic pain can be traced to a specific injury that has long since healed -- for example, an injury, a serious infection, or even a surgical incision. Other cases have no apparent cause -- no prior injury & an absence of underlying tissue damage.) There are psychological, physiological, & monetary reasons for the development of chronic pain. (Weintraub, 1996; Markenson, 1996) Examples are: o Hysterical conversion reaction = a subconscious, neurotic behavior that alters sensory & voluntary motor systems producing bodily dysfunction. Symptoms arise because the patient wishes to obtain some gain. (Financial or interpersonal) o Neurotic o Malingering = the false & fraudulent imitation or exaggeration of physical disease or mental symptoms in order to obtain financial reward. o Peripheral mechanisms (pathological causes) = include stimulation of nociceptors through injury or inflammation with liberation of serotonin, histamine, bradykinin, & prostaglandins. o Facet syndrome, sprain/strain, cancer, infection, abscess, fractures, arthritis, scoliosis, disc disease, stenosis, SI joint syndrome, Failed back surgery, visceral causes, etc o Psychophysiology = stress can produce muscle spasm, local vasoconstriction, visceral dysfunction, & liberation of endogenous pain-producing substances. o Stress o Decompensation = due to some sort of injury or illness, the musculature is not used & becomes unable to meet the functional demands imposed on them. Decompensation is a functional not an organic term; it cannot be seen in roentgenograms, myelograms, or in results of other laboratory studies. o Secondary to something else Epidemiology: Prevalence is increasing o F >M o 45-65 yrs has highest range Risk Factors: o overweight/obesity o pregnant o lack of exercise o stressed or depressed o Have a job in which require lifting, bending & twisting, or that involves whole body vibration (such as truck driving or using a sandblaster) o Smoker o Poor job satisfaction depressed o Patients with compensation issues (monetary) 127 Ortho Lecture Notes Combined o Medications = taking prescription analgesics for a long period of time, possible addiction issues o Poor sleeping habits Ex of conditions that may result in LBP chronic pain (see photo) Clinical Presentation: Low back pain can differ from person to person. The pain may be mild, or it can be so severe that patients are unable to move. o Dull aching o Sharp pain o Tingling or burning sensation o Weakness in legs or feet o Symptoms must last >3 months o Other symptoms are possible depends on the original cause of the pain o Possible Minor’s sign & other guarded movements (ex: disrobing) o Generalized tenderness o Tightness &/or loss of ROM & flexibility tests (asymmetrical muscle firing with respect to flexion & extension (Janda) o Dural tension signs may or may not be positive and/or provoking o Neurological signs may or may not be present o Waddell’s non-organic signs (credible tool for screening for psychological distress, however the presence of these signs does not imply a causal relationship & should be conceptualized as one component of a biopsychosocial model of chronic pain – meaning there may be psychological factors related to functional status & response to treatment) Diagnosis studies: Used to r/o non-mechanical causes of the LBP o Blood tests, especially a complete blood count & erythrocyte sedimentation rate o Plain film radiography o CT scan of the lower spine o MRI scan of the lower spine o Myelogram Management o Cognitive behavioral therapy CBT to help w/constant pain o Fear-avoidance therapy o Cold & heat therapy o Spinal manipulation – CMT Manipulation is slightly better than pain clinics (Wilkey,2008) o Acupuncture/acupressure o Foot orthotics o Soft tissue techniques - shown to have some benefit in subacute & chronic non specific LBP o Traction o Exercise therapy - core stabilization, stretching, strengthening, endurance training, proprioception retraining & cardiovascular exercises – has a positive effect on chronic LBP & was better than medical treatment, bed rest & patient instructional information (Aure, 2003; Amato, 2004) o NSAIDs, topical analgesics o Dietary intervention – possible weight loss, anti-inflammatory diet, use of glucosamine sulfate (bony & cartilaginous repair) LOSE WEIGHT almost always helps o Advise to be active (normal ADLs) – as effective as PT (Frost,2007) o Medium-firm mattress (Kovacs, 2003) 128 Ortho Lecture Notes Combined o Occupational therapy - Work hardening programs - objective is to increase the injured person’s functional capacity & productivity through individually prescribed, graded work tasks. Program length is 4-6 weeks. o Vocational rehabilitation Work Hardening 8 hr training o RX: NSAIDs, Anti-convulsants, Opioids, Muscle relaxants, Non-opioid analgesics o Epidural/intrathecal Injections &/or pain pumps o Spinal cord stimulator o Prolotherapy – is effective (Dagenais, 2008) o Spinal Surgery Lumbar Instability (M53.2X6) Definition: An abnormal response to applied loads & is characterized by movement of spinal segments beyond the normal constrains” Types: "Functional Lumbar Instability (FLI)" clinical instability = lack of neuromuscular control of the joint during activities o Altered motion during sagittal motions o Loss of NM control during mid-range motion = lack of stability in neutral zone o Motion may be increased or just aberrant "Mechanical Lumbar Instability (MLI)" - radiographic instability structural – disruption of the passive stabilizers & decreased structural integrity. Several causes are but not limited to: degenerative disease, trauma, postop, or cancer. This decreased stability can produced pain during normal activities. o Radiological signs (e.g., spondylolisthesis, spondylolysis) o P-A mobility assessment o TX = Surgery or Rehab Clinical Presentation o Lower back pain, which +/- sciatica. o Painful locking, catching, arc with movements in the spine (e.g. returning from forward bending) o Sudden pain during normal activities “sudden catching” o Problems in unsupported sitting & increasing pain in sustained positions o Pain in the morning &/or with weather changes o Rest may help, depending on the position Examination Findings: o Observation - while entering & moving about the treatment area. Moving into the seated position may be difficult for them, as well as moving from a seated to standing position (Magee, 2006). An ‘instability jog’ or twitching also may be seen in the muscles during an active movement (Magee, 2006). o Step defect?? o P-A Glide = This test assesses glide of each segment from posterior to anterior. o Kappa = .71 for the least mobile segment o Kappa = .29 for the most mobile segment o Which means it’s not a reliable method of identifying the most mobile segment but it is for identifying a segment that is stiff or resistant to motion. o AROM - to identify which movements are the most painful or difficult (Beazell et al. 2010). o Aberrant Motion = Although this is a qualitative test there is a moderate rating for interrater agreement. Kappa = .60. 129 Ortho Lecture Notes Combined o The patient is standing & asked to forward flex. Observe if there is an: • Instability catch • Painful arc of motion on flexion • Painful arc of motion on return from flexion • Thigh climbing • Reversal of lumbopelvic rhythm o Ortho tests o SLR = SLR ≥91° passive may indicate lumbar instability. • excellent inter-examiner reliability ICC=.94-.96. • other reasons besides lumbar instability possible so it must be interpreted cautiously & correlated with the other tests & history. o Double SLR Test o Prone Instability Test = This test has a high Kappa rating = .87. Case – a secreatery presents w/ intermit LBP, 1st thin in moring, and occasionally locks up. Sometimes feels unstable… Diagnosis studies: MRI look for soft tissue causes, but could still be functional if negativeo The use of MRI in diagnosing lumbar spine dysfunction has increased in the past two decades. The degree of disc degeneration, using standard MRI, is not thought to correlate with the amount of angulation (> 15°) or segmental instability (> 3 mm translation) (Beazell et al. 2010). o An MRI can be used to measure the current status of the intervertebral discs, facet joints, & ligamentum flavum, which should be taken into consideration when evaluating stability within the lumbar spine (Kong et al. 2009). o Functional instability can exist without any radiological evidence (Alqarni et al. 2011). X-Ray - indirect signs associated with spinal instability: e.g. osteophytes o Moderate disc degeneration with mild space narrowing, osteosclerosis & osteophytosis of the vertebral end plates (Kirkaldy-Willis 1985[6]) o Presence of traction spur, which is a particular type of osteophyte that is located 2-3 mm from the end plate & has a horizontal orientation. (Remy et al 2001[7]) o Intervertebral vacuum phenomenon is due to rupture of the insertion of Sharpey’s fibres & may be the result of vertebral instability (Alam 2002[8]) Management: Treatment for lumbar instability may depend on whether the instability is MLI or FLI. # 1 = Exercise Strength training of trunk extensor muscles can be considered as part of functional treatment (Davarian et al. 2012). *note that functional issues can become mechanical o Patients can use core training exercises to maintain strength in the lumbar area using techniques such as Pilates or McKenzie. In the case of a MLI, the underlying cause of the instability must be treated. o Exercise Therapy - active care, stabilizing the spine through low load exercises & eventually strength training. o The body does it on its own stabilization through the degenerative cascade – Kirkaldy-Willis model. o Surgery also will stabilize the spine but there are significant risks with surgery. Prognosis: 130 Ortho Lecture Notes Combined The natural course of FLI is that it may continue to degenerate morphing into MLI eventually. Even with treatment this may occur. Ankylosing Spondylitis aka: Marie-Strumpell disease or Bechterew’s disease (M45.9) Definition: Chronic inflammatory condition involving the sacroiliac joints & axial skeleton, which is characterized by ankylosis & inflammation at the tendon insertions (enthesitis). Etiology: Exact cause of AS is unknown, genetics play a key role in AS. o Over 95% w/AS also "genetic marker" - a protein - called HLA-B27. This marker is found in over 95% of people in the Caucasian population with AS. Scientists suspect that other genes, along with a triggering environmental factor, such as a bacterial infection, are needed to trigger AS in susceptible people. HLAB27 probably accounts for about 40% of the overall risk, but then there are other genes working in concert with B27. Epidemiology: Males >F 10:1 Usually starts from 15 to 35 years old (<45 yrs) Risk Factors: Testing positive for the HLA-B27 marker A family history of AS Frequent gastrointestinal infections Clinical Presentation: Almost all cases of AS are characterized by acute, painful episodes (also known as "flares") followed by temporary periods of remission where symptoms subside. o Back pain & stiffness (usually buttock region initially) _3+ months Pain worse with rest Pain increase with walking Fatigue Weight loss, anorexia Bilateral SI joint tenderness/pain Increased thoracic kyphosis, painful gait & posture. Stooped “question mark” posture. Limited Lumbar ROM Loss of chest expansion measured at the nipple line <2.5cm, reflecting rib cage involvement. Occasional, peripheral joint involvement (large joints are more commonly affected) Extraskeletal manifestations affecting the cardiovascular system *MC cause of death o aortic insufficiency o heart block o cardiomegaly o lungs (pulmonary fibrosis) o eye (uveitis) + Schober's test is a useful clinical measure of flexion of the lumbar spine performed during examination. (Silman 1998) 131 Ortho Lecture Notes Combined + Amoss + Forester Bowstring AS may have a relationship to intestinal dysfunction. Screen for increased intestinal permeability (“leaky gut syndrome”) & intestinal dysbiosis Clinical Diagnosis = Rome Criteria: LBP & stiff >3 months duration that is not relieved by rest thoracic region Pain & stiffness Limited ROM: lumbar spine in sagittal & frontal planes Decreased chest expansion History of uveitis Diagnosis studies: X-ray - bilateral sacroiliitis (initial widening due to inflammation fusion), verebral bodies may become demineralized & a typical "squaring off" occurs, Calcification of annulus fibrosus & paravertebral ligaments bamboo spine. Drawback of X-ray = signs & symptoms established as long as 8–10 years prior to X-ray-evident changes occurring on a plain film X-ray. Elevated ESR & CRP Absence of rheumatoid factor Presence of HLA/B27 antigen 90% of patients Management Manipulation contraindicated in inflammatory stage. o May be tolerated after acute phase with no excessive force. o Gentle manipulation of costovertebral joints may be beneficial to normal respiratory movt. o Beware of osteopenia, aortic aneurysm, dens erosion Postural training - avoid stooping Sleeping training - supine on firm mattress, no pillows under head, knees. Swimming, stretching, hyperflexion/hyperextension exercises may prevent flexion deformities Modalities may benefit pain relief. Avoid moderate to high impact exercises like jogging Diet: Low-saturated-fat, fresh (whole) food is recommended. o Limit/eliminate: Coffee, tea, alcohol, fried foods, simple carbohydrates Home Care Protocols o Perform ROM, posture, & breathing exercises. o Sleep supine on a firm mattress without a pillow. o Take daily warm baths for stiffness. o Avoid heavy lifting. o Practice standing & sitting up straight. NSAIDs, Opioid analgesics Surgery - option in the form of joint replacements, particularly in knees & hips Prognosis: Mortality is increased in patients with AS & circulatory disease is most frequent cause of death (Bakland et al. 2011) Coccydynia (M53.3) 132 Ortho Lecture Notes Combined Definition: Pain in the coccyx. Despite its small size, the coccyx has several important functions. insertion site for multiple muscles, ligaments, & tendons, serves as one leg of the tripod-along with the ischial tuberosities-that provides weight-bearing support to a person in the seated position.

Clinical Presentation Symptoms are variable in intensity & onset, & may include one or more of the following: Altered sensation, or severe or progressive weakness or numbness in lower extremities, legs and/or feet, possibly difficult to walk Loss of sensation or a strange sensation in the "saddle" area (the area of the body that would sit on a saddle: inner thighs/between the legs, buttocks, back of legs, sacral region) Urinary or bowel incontinence, including any dysfunction that causes retention of urine, inability to hold urine in, or loss of rectal control Lower back pain, which may be described as an aching pain in a localized area Sharp stabbing pain in the leg. o Saddle & perineum anesthesia o Sensory changes in the extremities o Motor weakness, which can progress to paraplegia o Neuro deficits may become permanent after 48 hours (death of the neuron) o Note in the initial stages findings may be subtle Diagnosis studies: o Plain film radiography may show signs of trauma (fracture/dislocation) or other condition (stenosis/bone pathology/tumor) that has affected the cauda equina o MRI/CT may show the compression Management Emergency surgical decompression to reduce or eliminate pressure on the nerve. Although there is no prospective randomized trial to confirm without a doubt, it is generally thought that surgery within 24 to 48 hours gives the maximum potential for improvement of sensory & motor deficits as well as bladder & bowel functioning, & most surgeons recommend surgery to decompress the nerves as soon as possible, within about 8 hours of onset of symptom ( Ahn et al 2000).

HIP Fracture (Full & Stress Fractures of the Hip) M84.359 Stress fracture, hip, unspecified, M84.459A Pathological fracture, hip Etiology: Hip fractures most commonly occur from a fall or from a direct blow to the side of the hip. Some medical conditions such as osteoporosis, cancer, or stress injuries can weaken the bone & make the hip more susceptible to breaking. In severe cases, it is possible for the hip to break with the patient merely standing on the leg & twisting Stress fractures of the hip once most commonly affected military personnel who marched & ran day after day. Today, stress fractures of the hip are more common in athletes, especially distance runners. Pathogenesis: There are two types of stress fractures. Insufficiency fractures are breaks in abnormal bone under normal force. Fatigue fractures are usually caused by new, strenuous, very repetitive activities, such as marching or distance running. Fatigue fractures are breaks in normal bone that has been put under extreme force. Most stress fractures of the hip are fatigue fractures. There are three different types of hip fractures. The type of fracture depends on what area of the upper femur is involved. Intracapsular Fracture: These fractures occur at the level of the neck & the head of the femur, & are generally within the capsule. The capsule is the soft-tissue envelope that contains the lubricating & nourishing fluid of the hip joint itself. Twice as common as other hip fractures & are more likely to result in serious complications such as osteonecrosis, nonunion, thromboembolic disease & osteomyelitis. Intertrochanteric Fracture: This fracture occurs between the neck of the femur & a lower bony prominence called the lesser trochanter. The lesser trochanter is an attachment point for one of the major muscles of the hip. Intertrochanteric fractures generally cross in the area between the lesser trochanter & the greater trochanter. The greater trochanter is the bump you can feel under the skin on the outside of the hip. It acts as another muscle attachment point. Subtrochanteric Fracture: This fracture occurs below the lesser trochanter, in a region that is between the lesser trochanter & an area approximately 2 1/2 inches below. When a stress fracture occurs in the hip, it usually involves the femoral neck. Compression fractures occur on the underside of the femoral neck. 137 Ortho Lecture Notes Combined Tension fractures occur on the upper side of the bone & can cause more problems than fractures on the underside of the femoral neck. Displaced fractures, the bone cracks all the way through, & the two bones no longer line up correctly o A displaced stress fracture is a very serious problem in a young adult because it may lead to damage to the blood vessels going into the upper end of the hip bone. This can cause a very serious complication known as avascular necrosis (AVN) of the hip. Stress fractures can also happen in the shaft of the femur bone, the greater trochanter, & the pelvis bone. Epidemiology: Lifetime risk factor in woman for fracture is ~16% F>M 3:1 90% of hip fractures are over age 60. Risk Factors: Age. The rate of hip fractures increases substantially with age.. Most hip fractures occur in people older than 60, with the risk increasing most rapidly after age 80. F>M. Women lose bone density at a faster rate than men do. The drop in estrogen levels that occurs with menopause accelerates bone loss, increasing the risk of hip fractures. Chronic medical conditions. Osteoporosis is the most powerful risk factor for hip fracture, but other medical conditions may lead to fragile bones. These include endocrine disorders, such as an overactive thyroid, & intestinal disorders, which may reduce absorption of vitamin D & calcium. Certain medications. Cortisone medications, such as prednisone, can weaken bone if you take them long term. In some cases, certain drugs or the combination of medications can make patient dizzy & more prone to falling. Nutritional problems. Lack of calcium & vitamin D in your diet when young lowers peak bone mass & increases risk of fracture later in life. Serious eating disorders, such as anorexia nervosa & bulimia, can damage skeleton by depriving body of essential nutrients needed for bone building. Physical inactivity. Weight-bearing exercises, such as walking, help strengthen bones & muscles, making falls & fractures less likely. Tobacco & alcohol use. Smoking & drinking alcohol can interfere with the normal processes of bone building & remodeling, resulting in bone loss. FRAMO Index consists of 4 independent risk factors Albertsson DM, et al. Validation of a 4-item score predicting hip fracture & mortality risk among elderly women.

A bone scan may be suggested to look for early signs of a stress fracture. MRI is especially useful in telling fatigue fractures from other types of injuries with similar symptoms. The MRI is being used increasingly in cases where doctors suspect a stress fracture. Treatment: Fractures: Referral Stress Fractures: Non-weight bearing recommended for 4-6 weeks, x-rays taken every two weeks to confirm healing. Medical Management: If the tension fracture is in danger of displacing, however, most surgeons will operate. This is because the complication of AVN can cause the femoral head to actually lose its blood supply & collapse Pediatric Conditions – Refer to Souza; see supplemental below Blaszko Helming, MA.

Because they do not fit together perfectly, the hip bones rub against each other & cause damage to the joint. Pathogenesis: FAI, bone spurs develop around the femoral head and/or along the acetabulum. The bone overgrowth causes the hip bones to hit against each other, rather than to move smoothly. Over time, this can result in the tearing of the labrum & breakdown of articular cartilage (osteoarthritis) Types of FAI: There are three types of FAI: pincer, cam, & combined impingement.. Etiology: FAI occurs because the hips do not form normally during the childhood growing years. It is the deformity of a cam bone spur, pincer bone spur, or both, that leads to joint damage & pain. When the hip are shaped abnormally, there is little that can be done to prevent FAI. Because athletically active people may work the hip joint more vigorously, they may begin to experience pain earlier than those who are less active. However, exercise does not cause FAI. 141 Ortho Lecture Notes Combined Clinical Presentation Pain in the groin area, although the pain sometimes may be more toward the outside of the hip. Sharp stabbing pain may occur with turning, twisting, & squatting Sometimes just a dull ache. +Anterior or Posterior Impingement tests Diagnosis studies: X-rays. These provide good images of bone, & will show whether your hip has abnormally shaped bones of FAI. X-rays can also show signs of arthritis. Computed tomography (CT) scans. More detailed than a plain x-ray, CT scans help doctors see the exact abnormal shape of hip. Magnetic resonance imaging (MRI) scans. For soft tissue damage Management Activity changes. Avoiding activities that cause symptoms. Non-steroidal anti-inflammatory medications. Exercise therapy. Specific exercises can improve the range of motion in hip & strengthen the muscles that support the joint. This can relieve some stress on the injured labrum or cartilage. Surgery Hip Labral Tears S73.191A (rt hip), S73.192A (lf hip) Etiology: Trauma. Injury to or dislocation of the hip joint — which can occur during car accidents or from playing contact sports such as football or hockey — can cause a hip labral tear. Structural abnormalities. Some people are born with hip problems that can accelerate wear & tear of the joint & eventually cause a hip labral tear. Example FAI Repetitive motions. Sports-related & other physical activities — including the sudden twisting or pivoting motions common in golf or hockey — can lead to joint wear & tear that ultimately results in a hip labral tear. Epidemiology: Active adults between the ages of 20 -40 are affected most often. Athletes who participate in such sports as ice hockey, soccer, football, golf & ballet are at higher risk of developing a hip labral tear. Structural abnormalities of the hip also can lead to a hip labral tear. Most studies report that symptomatic labral tears occur more frequently in women than in men. Clinical Presentation Pain anterior hip (most often in the groin area) accompanied by clicking, locking, or catching of the hip are the main symptoms reported with hip acetabular labral tears. Joint stiffness & a feeling of instability where the hip & leg seem to give away are also common. The pain may radiate (travel) to the buttocks, along the side of the hip, or even down to the knee. Symptoms get worse with long periods of standing, sitting, or walking. Pivoting on the involved leg is avoided for the same reason (causes pain). Some patients walk with a limp or have a positive +Trendelenburg sign (hip drops down on the right side when standing on the left leg & vice versa). The pain can be constant & severe enough to limit all recreational activities & sports participation. Burnett & colleagues studied 66 patients found to have labral tears by arthroscopy & reported 92% had predominant localized groin pain, 52% had associated anterior thigh pain, 59% described lateral hip pain, & 38% reported associated buttock pain, while no patient presented with isolated 142 Ortho Lecture Notes Combined buttock pain. (Hunt D, Clohisy J, Prather H. Acetabular tears of the hip in women. Phys Med Rehabil Clin N Am. 2007;18(3):497–520.) + FADIR Impingement Test Diagnosis studies: X-rays. X-rays are excellent at visualizing bone. However, X-rays don't produce images of soft tissue, so these images can't be used to diagnose a labral tear, only to rule out fractures or structural abnormalities. Magnetic resonance imaging (MRI). MRI alone is inadequate for visualizing the acetabular labrum. Standard MRI produces both false-positive results & an underestimation of labral pathology & has only 30% sensitivity & 36% accuracy Magnetic resonance angiogram (MRA). MRA produces better results, as the intraarticular or systemic infusion of gadolinium is required to obtain the detail necessary to study the labrum. The sensitivity & accuracy increased to 90% & 91%, respectively. Management Rest Anti-inflammatories Physical therapy - with the goal of optimizing the alignment of the hip joint & the precision of joint motion by reducing anteriorly directed forces on the hip & addressing abnormal patterns of recruitment of muscles that control the hip Arthroscopic Surgery – When conservative treatment fails. Sports Hernia aka: athletic pubalgia, hockey groin, sportsman’s hernia Definition: Persistent unilateral groin pain, often in an athlete, in which there is no demonstrable hernia; therefore it is a clinical diagnosis. However, during surgery a small number of occult hernias was identified. There is a strain or tear of any soft tissue (muscle, tendon, ligament) in the groin. Etiology: Chronic, repetitive trauma/stress to the tissue (high speed twisting, bending, torqueing the groin Pathology: Most probable is tear of the external oblique aponeurosis with subsequent injury to the ilioinguinal nerve as it passes through area May be Osteitis pubis or musculotendinous strain to adductor Epidemiology: M>F Sports: hockey, rugby, soccer, football, wrestling Clinical Presentation: Severe pain in groin area Better with rest, but once return to sport pain returns May be exacerbated by sudden increase in intra-abdominal pressure (coughing, sneezing) May be provoked by performing sit-up or crunches Palpation of the adductor may produce tenderness Forced adduction against resistance (supine, knees bent, heels together) is typically provoking Diagnostic Studies: Ultrasound is best to determine abnormalities in inguinal canal 143 Ortho Lecture Notes Combined MRI may reveal muscular abnormalities Bone scan might be helpful if trying to r/o or r/i Osteitis Pubis Treatment: Non-surgical Rest – first 7-10 days after initial injury Cryotherapy = 3-4x/day for 10min Physical Therapy – 2 weeks after injury strength & flexibility exercises NSAIDs – Ibuprofen or Naproxen Cortisone steroid injections Conservative care doesn’t usually provide long-term relief in an athlete Surgery is the most common treatment for Sports hernias Laparoscopic mesh repair - > 90% success rate – Return to play within 6-12 wks post-surgically Lateral Femoral Cutaneous Nerve Compression (L2-L3) Meralgia paresthetica, unspecified lower limb G57.10 Right lower limb G57.11 Left Lower Limb G57.12 SENSORY Definition: The lateral femoral cutaneous nerve, a pure sensory nerve, is susceptible to compression as it courses from the lumbosacral plexus, through the abdominal cavity, under the inguinal ligament, & into the subcutaneous tissue of the thigh. Most often under the inguinal ligament. Epidemiology: More prevalent in diabetics Age: 50 + Gender: M=F Etiology/Risk Factors: increase intraabdominal pressure (pregnancy) obesity trauma tight clothes prolonged hip flexion (i.e. lying in a fetal position), diabetes masses (eg, neoplasms, contained iliopsoas hemorrhages) in the retroperitoneal space before it reaches the inguinal ligament & toxins. Patient Symptoms: Dull ache, itching, numbness, tingling, or burning sensation over the lateral & anterolateral thigh. Aggravated by standing or hip extension (i.e., walking) Relieved by sitting.

Nerve then dives into the fibularis longus muscle, where tethering can occur, making it susceptible to stretch injury at this level. The nerve then divides into the superficial & deep branches. *more commonly injured than tibial of Sciatic N Etiology: vulnerable to injury where it winds around the fibular head (varus stress injuries &/or fibular fractures) this may occur in people who habitually cross their legs. Baker’s cyst may entrap the nerve. Cast or elastic stockings may compress the nerve. Prolonged immobilization (comatose patients, sitting on a plane, postsurgical) or the peroneal nerve, if tethered where it dives into the peroneus longus muscle, also may be damaged by stretch injury. Prolonged squatting or a sudden stretch. Diabetes. Inversion Sprain Clinical Manifestations: Steppage (equine) gait. It is usually an acute onset. It may be complete can’t dorsiflex the foot or toes or partial DROP FOOT Numbness in distribution of nerve. Night cramps in the calf in the chronic patient *due to stuck in plantar flexion Pain may occur at the site of compression. Tinel’s sign may be elicited when percussion of the nerve around the fibular neck. Management Usually recovery foot drop is spontaneous (in 2-3 months) but a brace would be beneficial to assist with ambulation. The recovery may not be complete. Adjust the back, hip, & knee as indicated. Avoid crossing the legs, squatting for long periods of time. Protective kneepads placed over the fibular head & neck, especially if the patient underwent a recent weight loss.

Iliotibial Band Friction Syndrome (ITBS) M76.30 Description: One of MOST common cause of lateral knee pain knee in runners & cyclists; pain develops where the ITB runs over the lateral epicondyle, less commonly it can create lateral thigh pain where band runs over greater trochanter Fat pad under IT band gets inflamed & compresses blood supply Etiology: combination of repetitive stress & biomechanical factors IT band attaches to Tibia & patella Risk Factors: tightness of ITB weakness of hip abductor, esp G. medius *increases valgus forces low hamstring strength compared to quadriceps strength on same side femoral external rotation o or internal knee rotation angle of knee flexion – o bike seat too low ITB most likely to rub against or compress underlying structures at position of 20-30 degrees Foot on pedal should be parallel to ground leg length discrepancy (injury to longer leg Right leg on roads, Left leg on track) o Running on banked road abnormal foot & ankle mechanics (rear foot pronation, internal tibial rotation) abnormal knee mechanics (valgum, varum shoe breakdown, esp on the lateral heel training intensity errors – increase mileage or intensity to fast Incorrect saddle height (to low) or position (to far back) in bikers Running on slanted surfaces o Run with the traffic tend to have ITB troubles in their right thigh because that leg must travel a greater distance each time it hits the ground) o Run track (ITBS in the left thigh because the ITB must control a greater deceleration of adduction in the left hip. Epidemiology: F>M (slight difference) 15-50 yrs Prevalence varies between 2 & 25% in physically active Pathology: o Most commonly thought pathophysiological cause of IT band syndrome is by excessive friction 148 Ortho Lecture Notes Combined o distal iliotibial band as it slides over the lateral femoral epicondyle during repetitive flexion & extension of the knee resulting in friction & inflammation of the band & underlying soft tissues. o Other research suggests that the highly vascular fat pad that is located beneath the IT band at this location is the source of pain. o When the knee is flexed (bent) the tibia rotates internally (inward) if there is no compensating external rotation of the femur (hip bone) the IT band increases compressive forces on the lateral aspect of the knee. o The increased compressive forces prevent blood flow from passing through the fat pad. With the decreased blood flow inflammation occurs within the fat pad causing pain. The pain is usually at its highest intensity when the knee is flexed at 30 degrees. Clinical Presentation: Lateral knee pain (possible lateral hip pain) initially during activity, then persists after the activity with progression Achy, burning pain that can progress to sharp pain around lateral epicondyle Pain may radiate down to the tibia, occasionally radiates up the lateral thigh Pain worsens at heel strike or as knee extends during biking Pain that is worse when running down hills or stairs, on banked tracks, or next to the curb on the street Possible snapping hip or snapping at knee Possible stiff-legged gait Tenderness 2-3cm prox to lateral joint line @ IT band Possible “wet leather” crepitus (spongy) Possible localized swelling Possible TrPs in the vastus lateralis, g. medius, biceps IT band Groove over lateral thigh “visible tightness” AROM – greatest provocation at @ 30 degrees, PROM – not as provoking greatest force on protuberance of lateral epicondyle Strength of the lower extremity should be assessed with particular emphasis on examining the knee extensors, knee flexors, & hip abductors. o Weakness in these muscle groups has been associated with the development of iliotibial band syndrome (Fredrickson et al.

Epidemiology: Approximately 8% of all knee injuries is the LCL (e.g., 2nd least commonly injured ligament of the knee) *PCL is least commonly injured General Risk Factors for knee injuries: o Female athletes o Competition vs practice o Playing in a sport that requires a lot of pivoting, jumping, contact Clinical Presentation Pain over lateral knee, especially with walking/running on uneven surface o DDX: IT band Effusion, limp (foot drop with nerve injury), ecchymosis o Swelling over the site of the injury. o Instability — the feeling that your knee is giving way. o Paresthesias if common fibular nerve injured…foot drop Tenderness or ligamentous defect (easier to palpate if knee is in a figure 4 position or pt supine with knee flexed to 90 & foot on flat on table) If knee is dislocated perform ABI; if result is <0.9 get arteriogram & vascular consult Patient maintains a flexed knee position during gait ROM slightly limited (+) Adduction stress (need to check other structures too) Possible motor/sensory changes with fibular nerve damage Classification of LCL injury *KNOW GRADES o Grade 1 – Mild sprain = result in localized tenderness. Laxity & mechanical symptoms are not present o Grade 2 – Partial tear = tenderness may be localized or diffuse along the lateral & posterolateral knee. Some swelling may be present. Mild to moderate laxity can be demonstrated (5 to 10 mm) but has a solid endpoint. o Grade 3 – Complete tear = varying degrees of pain; laxity without a solid endpoint & the patient experiences one or more mechanical symptoms. These injuries are often associated with posterolateral corner (PLC) pathology. Diagnostic Studies: Plain film =, Ottawa rules stipulate that tenderness of fibular head is grounds for imaging o Possible “Arcuate” sign = avulsion of fibular head styloid which is pathognomonic for Posterolateral corner (PCL) injury & possible distal LCL avulsion o Segond Fx (avulsion fracture of lateral tibial plateau) ACL tear may also indicate a LCL tear 158 Ortho Lecture Notes Combined o Varus stress views MR - is diagnostic US – is also diagnostic Management Grade I-II (isolated LCL tears) can be managed non-operatively with: o a protective hinged knee brace initially locked in extension but the patient should be able to do full weight bearing o Cryotherapy o Perform full ROM in the prone position o Strengthening the dynamic stabilizers o Should be able to return to sport-specific therapy in 4-6 wks if strength & ROM is comparable to uninjured side Grade III tears = best managed w/surgery operatively because they usually involve the arcuate ligament complex & popliteus muscle. Posterior Cruciate Ligament Sprains S83.529A Etiology: High-energy mechanism – MVA (not likely to be isolated injury) o Posteriorly directed shear force to a flexed knee “dashboard injury”; if varus stress included there is also a lateral or Posterolateral corner injury o Knee flexed & hit tibia hard Low-energy mechanism o Fall on flexed knee with ankle in plantar flexion o Direct blow to anterior knee o Hyperflexion or hyperextension +/- posteriorly directed force o Valgus or varus force (will not result in an isolated injury) Epidemiology: Isolated PCL injury is rare < 7.5% of trauma related injuries, most likely to also involve the Posterolateral corner, ACL &/or MCL Least common ligament to be injured Many who obtained isolated PCL can still function at a high level so do not present to a clinician 45% of injuries associated with MVA, 40% were athletic injuries Grades of Injury o Grade 1 – Anterior border of the medial tibial plateau can be displaced posteriorly but remains anterior to medial femoral condyle (0-5 mm posterior displacement). Tib still anterior o Grade 2 – Anterior border of medial tibia plateau can be displaced posteriorly until it is flush with medial femoral condyle (posterior displacement of 5-10 mm). Tib flush w/condyles o Grade 3 – The anterior border of medial tibial plateau can be displaced posteriorly beyond anterior border of the medial femoral condyle (posterior displacement >10 mm). Tib post of condyles Risk Factors o football, soccer, skiing, baseball 159 Ortho Lecture Notes Combined Clinical presentation: Asymptomatic or minimal symptoms *likely still functional Pain & stiffness (not usually due to the ligamentous damage more likely associated with bony contusion in the area) in the acute injury Heard/felt a pop, although this less likely in an isolated PCL tear Possible feeling of instability, others are unaware of the sprain (no instability) Chronic injury may lead so symptoms associated with osteoarthritis Possible increase in symptoms in chronic tears while using stairs, walking on inclines or decelerating Nothing overt on exam or: Effusion, erythema, ecchymosis? possible atrophy, signs of mal-alignment Chronic pcl deficient knee may demonstrate tibia vara & genu recurvatum “varus thrust” gait Tenderness ROM full or limited flexion if effusion is present, possibly provoking (+) Drawer, (+,-) Hughston’s Drawer, (+) Posterior sag (chronic injury), (+) Quadriceps active test – quad contracts & pulls tibia forward Diagnostic Studies: Plain film rule/out avulsion (use Ottawa rules in decision making process) - can provide information about a PCL injury. They can detect pieces of bone that may have broken loose from the injury MR can find the exact location of a tear. US has limited use Arthroscopy in some instances Treatment: Referral is indicated if: Grade 3 tear, associated fracture, associated soft tissue injuries, &/or avulsion of the ligament from the tibia PRICE Mobilization - passive ROM Bracing if instability – o hinged brace locked in full extension for 2 wks to reduce posterior lag; o after 2 wks unlock brace to allow progressive ROM exercises (Chronic PCL deficient knee doesn’t require bracing unless patient is reporting a high degree of instability) Weight bearing or non-weight bearing? *avoid OKC hamstring flexion Modalities = neuromuscular electrical stimulation to the quads Exercise therapy. As the swelling goes down, a careful rehabilitation program is started. Specific exercises will restore function to knee & strengthen the leg muscles that support it. o Strengthening the muscles in the quadriceps has been shown to be a key factor in a successful recovery; start with open chain (quad setting exercises & ankle pumps) o Avoid open chain hamstring exercises initially (e.g. sliding heel on table &/or resisted knee flexion to prevent unopposed activation of the hamstrings leading to an increase in sag) o Aquatherapy 160 Ortho Lecture Notes Combined o Possible taping during the exercises o Stationary bike Prognosis: Rehab for PCL tears takes longer than ACL tears. Post-surgical rehab protocols may take between 26-52 wks. If left untreated, patients reported occasional episodes of pain & had altered activity levels. o 90% of patients had progressive degenerative changes. Compartment Syndromes T79.A0XA *4 compartments in leg Definition: A painful condition occurs when pressure 1 of 4 leg compartments builds to dangerous levels, pressure can decrease blood flow, preventing nourishment & oxygen from reaching nerve & muscle cells. 4 compartments = anterior, deep posterior, peroneal, superficial posterior. Etiology: Acute Compartment Syndrome o Acute compartment syndrome usually develops after a severe injury, such as a car accident or a broken bone. Rarely, it develops after a relatively minor injury. o Conditions that may bring on acute compartment syndrome include: A fracture. A badly bruised muscle. Reestablished blood flow after blocked circulation. Crush injuries. Anabolic steroid use. Constricting bandages. Chronic (Exertional) Compartment Syndrome RUN, BIKE, SWIM o The pain & swelling of chronic compartment syndrome is caused by exercise. Athletes who participate in activities with repetitive motions, such as running, biking, or swimming, are more likely to develop chronic compartment syndrome. This is usually relieved by discontinuing the exercise, & is usually not dangerous. Epidemiology: o <35 yrs is most common age o M >F Compartments of the lower leg: 45% Anterior Compartment - Consists of the tibialis anterior, extensor hallucis longus, extensor digitorum longus, fibularis tertius, deep fibular nerve & the anterior tibial artery foot drop, top of foot numb 40% Deep Posterior - Consists of: tibialis posterior, flexor hallucis longus, flexor digitorum, tibial nerve, peroneal artery, & the posterior tibial artery numbness inside of foot & foot drop 10% Lateral Compartment - Consists of: fibularis longus & brevis & the superficial fibular nerve 5% Superficial Posterior -Consists of: gastrocnemius, soleus, plantaris, & the sural nerve Clinical Presentation Based on the involved compartment(s) 161 Ortho Lecture Notes Combined Example: o Anterior Compartment Syndrome: Transient or persistent footdrop with possible paresthesia. Paresthesia is often felt over dorsum of the foot. o Deep Posterior Compartment: Paresthesias of the instep of the foot Acute vs Chronic Compartment Syndrome Acute Sx’s onset during or after activity, pain starts as ache, increases to piercing, cramp like, or burning pain; pain is worse than what would be expected with the injury; accompanied by hypoesthesia & paresthesias (depending on compartment)? Feeling of tightness or fullness Signs turgid extremity, erythema, edema, increase temp in leg, pulse changes, temp changes in foot?, pain w/passive stretch, decrease sensation & paresis/paralysis are signs assoc w/permanent tissue damage Dx Hx, Px & compartment pressure Chronic Exertional Compartment Syndrome Asymptomatic at rest, w/activity pain, tightness, aching, cramping, transient weakness & paresthesia. Pts can give state precise area of pain & type of activity that induces pain. Symptoms typically start each time at either a given distance or intensity of running/exercise. Relief of symptoms comes when activity ceases (Wilder, 2004) dependent upon which compartment is involved: edema, tenderness, erythema, weakness, hypoesthesia, ischemia Mm bulging S/Sx resolve within 20 min of cessation of activity S/Sx only w/exercise; compartment pressures are increased w/exercise 5 P’s of acute: Pallor, paresthesias, paresis, pain, pulselessness 5 Ps of Acute conditions 1. Pallor 2. Pain 3. Paresthesisa 4. Paresis 5. Pulselessness Management: Acute compartment syndrome a surgical emergency. Compartment syndrome can develop 2 hours to 7 days after injury. Monitor for swelling. An ischemic event of 6 hours is sufficient to produce permanent muscle & nerve damage. Be prepared to refer for fasciotomy. Chronic compartment syndrome – o Surgery may be necessary if compartment pressures > 30 to 35 mm Hg. o If ischemia in soft tissues > 6 hours than permanent damage possible o Orthotics may be helpful. o Elevated pressures on a transient basis & influenced by activity, conservative management is felt to be effective o Rest is the only conservative measure that brings relief, although when activity is resumed the pain & compression returns. o Manipulation (joint & soft tissue) – flexibility & strength 162 Ortho Lecture Notes Combined o Anti-inflammatories & anti-inflammatory diet o Possible orthotics o May try running on softer surfaces o Cross train instead of focusing just on running o Ice following training surgery is required In cases where symptoms persist despite 6-12 weeks of conservative care, & pressure still high in cases with extreme pressure elevations.

It may build to an intense throbbing. Typically unilateral Exam may reveal one of the risk factors listed above Little to no ecchymosis or erythema Tenderness esp when toe is dorsiflexed Dorsiflexion of the 1st MTP provokes & maybe limited ROM Possible crepitus Dx is typically made by exclusion of other causes Diagnostic Studies: Plain film: usually unremarkable, possible bifed sesamoid MRI or plain film may show: osteochondritis or Fx Management: Cryotherapy 164 Ortho Lecture Notes Combined Activity modification avoid running (use non weight bearing aerobic activities) Orthotic or stiff soled shoe, avoid wearing high heels Donut support - a shoe pad to reduce pressure on the affected area. This may be accomplished by placing a metatarsal pad away from the joint so that it redistributes the pressure of weight bearing to other parts of the forefoot. Possible immobilization in cast/walking boot Taping the toe - big toe may be bound with tape or athletic strapping to immobilize the joint as much as possible & allow for healing to occur.

Atrophy of the intrinsic muscles of the foot is a rare finding & is only found in advanced cases. Weakness of toe flexion is the only reliable muscle finding, but it is only seen in approximately 19% of the cases. Differential Diagnosis: SEE PPT Medial Plantar Neuropathy (Jogger’s foot): Etiology, signs & symptoms are similar to TTS, except they are present only on the medial sole of the foot.

It is associated with calcaneal spurs, & the wearing of high heels (thus the colloquial term "pumpbump") or stiff-backed shoes in general. Etiology: Friction Pathogenesis: Bony growth (exostosis) that appears at the back of the heel at the insertion point for the Achilles tendon repetitive impingement of the bursa between the tendon & exostosis will create retrocalcaneal bursitis.

Acute achilles tendon ruptures. Orthopedics. 2010 Oct;33(10):758-64) Definition: Partial or complete rupture of the tendon (traumatic or nontraumatic); rupture is 2-6 cm proximal to insertion Epidemiology Incidence of rupture is 7/100,000 80% occur during recreational sports *weekend warriors Age: 20-50 yrs (mean age 40 in males, 44 in females) who are intermittently active Etiology (multifactorial) & Risk factors 171 Ortho Lecture Notes Combined Tendon rupture occurs when sudden forces are exerted upon the Achilles tendon during strenuous physical activities that involve sudden pivoting on a foot or rapid acceleration (eg, stop & go sports such as tennis, basketball, or softball) Overuse biomechanical malalignment hyperpronation & cavus foot marked forefoot varus medications that weaken Connective tissues inappropriate footwear overuse is most common cause in recreational athletes with acute rupture prolonged tendon degeneration or sudden severe stress can result in partial tearing or complete rupture Clinical Presentation Acute heel pain following running, jumping activity Pt may relate that it feels like they have been “kicked from behind” Pop w/hyper dorsiflexion Inability/difficulty with ambulation (some ruptures are missed because the patient can walk) Eccyhmosis, edema, visuable defect Tenderness Limitation or complete loss of active plantarflexion; weakness on resisted plantarflexion Difficulty to inability to do repetitive heel raises or toe walking + Thompson Diagnostic Studies US or MR to confirm dx Management Surgery – full thickness tears, get patient weight bearing in approximately 2 wks Non-surgical (partial) Ice, rest, NSAIDs with either: Serial casting progressing from plantarflexion to neutral to full dorsiflexion Solid removable boot with heel insert w/early mobilization Medial Ankle Sprains Definition: involves the ankle being forced into eversion & external rotation. Sprains to the medial ankle complex are less common because biomechanics of the ankle joint allow for less eversion than inversion. Also the deltoid ligaments (ant & post tibiotalar, tibiocalcaneal, tibionavicular) are strong & often an avulsion fracture at the medial malleolus occurs before a deltoid ligament sprain. Etiology Eversion stress, especially when landing on an uneven surface, cutting or stepping down a stair wrong In almost 60% of the eversion injuries avulsion of the tip of the medial malleolus occurs instead of a deltoid ligament sprain *60% of medial ankle sprains result in avulsion Epidemiology 10-18% of all ankle sprains are medial Risk Factors 172 Ortho Lecture Notes Combined male gender higher competition levels young populations intercollegiate rugby gymnastics soccer Clinical Manifestations Ankle sprains grades based on severity of damage to ligament complex. Grade 1: Partial tear/stretching of a ligament o Mild point tenderness o Minimal edema o Minimal to no loss of function; Patient should be able to tolerate weight bearing & perform daily activity without complaint of severe pain. o No mechanical instability; negative clinical stress tests. Grade 2: Incomplete tear of a ligament o Moderate pain & edema o Point tenderness over medial ankle complex o Mild to moderate ecchymosis o Loss of range of motion o Loss of function; Patient will complain of pain with weight bearing & ambulation. o Mild to moderate mechanical instability; Patient will have mild positive findings on the clinical stress tests. o + Medial stability test o + External rotation stress test Grade 3: Complete tear of a ligament o Severe edema o Severe ecchymosis o Severe loss of function; Patient will be unable to bear weight & ambulate. o Mechanical instability; Patient will have moderate to severe positive findings on clinical stress tests. Diagnostic studies Plain film – a space greater than 4mm between the talus & medial malleolus on the mortise view suggests a tear of the deltoid ligament. MRI - MRI must be used to determine partial & complete deltoid ligament tears to decide whether surgical fixation is necessary. Patients with partial tears are treated nonoperatively & can respond well to treatment Management PRICE o Protection-protect the ankle from further injury by resting & avoiding activities that cause pain. o Rest- the use of crutches will allow the ankle to rest until one can walk without pain. o Ice-apply ice to the ankle for 15-20 minutes as often as once per hour. o Compression- compression wraps are used to decrease swelling. o Elevation- elevate the ankle above the level of the heart to decrease swelling. Treatment is similar to lateral sprains although it takes longer. ROM exercises: It is important to begin range of motion exercises within pain free range as soon as possible. Active & passive range of motion exercises should be used to maintain range of motion for optimal function. Range of motion should be restored before beginning training in stabilization, 173 Ortho Lecture Notes Combined strength, proprioception & function. To improve or maintain ROM, stretching & joint mobs are commonly used: Stretching: Ankle Stretches (dorsiflexion, inversion): hold for 15 -30 seconds, 5 reps, every day. It is important to begin ankle dorsiflexion stretches early due to the Achilles tendon’s tendency to contract following injury. Alphabet exercises: Instruct the patient to draw the alphabet, one letter at a time A-Z. This exercise encourages movement of the ankle in all planes. Joint mobilizations: Anterior-posterior joint mobs: mobilizing the ankle into restricted planes can help to regain lost range of motion. Joint Stabilization: Stabilization is achieved through muscle strengthening exercises, balance, & proprioception exercises. Isometric Exercises: Resistance can be provided by an immovable object (wall or floor), elastic bands, or manual resistance. Exercises should be held for at least 6 seconds for maximal contraction, 10 repetitions & 3 sets daily. Exercise can be performed in dorsiflexion, plantarflexion, eversion, inversion, & eventually diagonals. Isotonic Exercises: Resistance can be provided by weights, theraband, or gravity. Exercises should be performed for 10-20 reps, 2-3 sets & up to 2 times a day depending on intensity. Each repetition should include concentric component & slow eccentric component. Exercises include plantarflexion push downward, dorsiflexion push upward, eversion & inversion. Balance & Proprioception training: Once balance is established, proprioceptive exercises can be progressed by: o Balance on even surface o Balance with eyes closed o Balance on balance board o High surface balance o High surface with eyes closed o High surface on balance board o Walking o Jumping Complete Ruptures – Referral for surgical stabilization. High Ankle Sprain aka: Tibiofibular Ligament or Syndesmosis Sprains Etiology External rotation force applied to dorsiflexed ankle (e.g., leg is rotated forcefully against a planted foot/toe) – most common Athlete is prone on the ground & another athlete steps or lands on their posterior leg while the foot is externally rotated Eversion of the ankle Hyper-dorsiflexion Severe inversion Epidemiology Approximately 10-20% of ankle sprains Risk Factors (Ivins D.

Athlete may be out for 6+ wks with this type of sprain Surgery – internal fixation Return to Play: One indicator that the patient is ready to RTP is the ability to hop on that foot 15 times without symptoms Prognosis Not as good as other sprains they usually take much longer to heal (i.e., double or triple the amount of time it will take them to heel). Greater risk for further ankle injuries following a high ankle sprain With internal fixation pts can return to full activity as early as 6 wks.
