Musculoskeletal Curriculum History & Physical Exam of the Shoulder Copyright 2005 Authors Kathleen Carr, MD Madison Residency Program Kathleen.Carr@fammed.wisc.edu Dennis Breen, MD Eau Claire Residency Program Dennis.Breen@fammed.wisc.edu 2 Goal Learn a standardized, evidence-based history and physical examination of patients with shoulder problems WHICH WILL: Enable family medicine resident physicians to accurately diagnose common shoulder problems throughout the full age spectrum of patients seen in family medicine 3 Competency-Based Objectives Patient care – focused history and exam Professionalism – respect, compassion Interpersonal and communication skills – differential diagnosis Medical knowledge base – anatomy, injury mechanisms Systems based practice – accuracy, time-efficiency 4 Shoulder Pain Key Points Shoulder pain is a common complaint in primary care Most common causes in adults (peak ages 40-60) Subacromial impingement syndrome Rotator cuff problems Athletic injuries 2nd only to knee pain for referral to Ortho or primary care sports med Shoulder accounts for 8-13% of athletic injuries History and examination are keys to diagnosis 5 Assessing shoulder pain Components of the assessment include Focused history Attentive physical examination Thoughtfully ordered tests/studies 1. 2. 3. for future discussion 6 Focused History Focused History Questions Onset of Pain When symptoms started* History of trauma/injury 8 Focused History Questions Mechanism of Injury Helps predict injured structure Example: Fall directly onto anterior/superior shoulderAC joint injury (shoulder separation) Example: Arm forcefully abducted and externally rotated subluxation or anterior dislocation Example: If chronic pain, note activity that triggers pain, such as the cocking phase of throwing or the pull-through phase of swimming 9 Focused History Questions Mechanism of Injury, continued Can determine radiological needs Likelihood of specific conditions varies Setting (work, recreation, sports, traumatic, atraumatic) Age of the patient* 10 Focused History Questions Location of pain* Anterior Lateral Superior Posterior Radiation of pain Rotator cuff problems often include pain radiating to upper arm If pain starts in neck and radiates to shoulder, consider cervical spine disease 11 Focused History Questions Consider sources of referred pain Cervical spine – spondylolysis, arthritis, disc disease Cardiac - myocardial ischemia Diaphragmatic irritation Thoracic outlet syndrome Gallbladder disease Complex regional pain syndrome (a.k.a, reflex sympathetic dystrophy) 12 Focused History Questions Characteristics of pain Night pain when lying on affected Rotator cuff tear side, muscle atrophy < 30 yo Biomechanical, inflammatory > 45 yo, Hx of trauma Rotator cuff tear - 35% of pts Painful arc (60-120°abduction) Pain > 120° abduction Catching, popping, clicking Subacromial impingement Acromioclavicular joint GH or AC joint arthritis, labral tear 13 Focused History Questions History of instability Aggravating factors Overhead work, repetitive movements, sports Relieving factors/treatments tried Glenohumeral subluxation or dislocation Rest, immobility, medications, other treatments History of Prior Shoulder Problems or Surgeries 14 Differential Diagnosis Diagnosis Primary Care % Age Subacromial Impingement Syndrome 48-72 23-62 Adhesive Capsulitis 16-22 53 Acute Bursitis 17 - Calcific Tendonitis 6 - Myofascial Pain Syndrome 5 - 2.5 64 2 - 0.8 - Glenohumeral Joint Arthrosis Thoracic Outlet Syndrome Biceps Tendonitis 15 Physical Exam Physical Exam - General Develop a standard routine Alleviate the patient's fears Adequate exposure - bilateral Males – shirtless Females – tank top or sports bra Compare shoulders 17 Physical Exam – Steps* Inspection Palpation Range of motion (ROM) Strength testing Special tests 18 Inspection Swelling, asymmetry, muscle atrophy, scars, ecchymosis and any venous distention Note posture (e.g., shoulder protraction) Deformities Squaring of shoulder - anterior dislocation Scapular "winging" - shoulder instability and serratus anterior or trapezius dysfunction Atrophy - supraspinatus or infraspinatus consider rotator cuff tear, suprascapular nerve entrapment or neuropathy 19 Palpation Sternoclavicular joint Clavicle Acromioclavicular joint Subacromial bursa Coracoid process Bicipital groove Greater tuberosity Lesser tuberosity Scapula (spinatus muscles) TIP: Start medially at the SC joint, proceed laterally, end posteriorly 20 Anterior Shoulder http://www.nismat.org/orthocor/exam/shoulder.html#Functions 21 Posterior Shoulder http://www.nismat.org/orthocor/exam/shoulder.html#Functions 22 Palpation of AC Joint Patient's arm at his/her side Note swelling, pain, and gapping. 23 Palpation of Bicipital Groove Patient sitting, beginning with the arm straight Patient actively flexes biceps muscle while examiner provides supination and ER Examiner palpates the bicipital groove for pain 24 Range of Motion (ROM) Evaluate active ROM If movement limited by pain, weakness, or tightness, assist passively Lack of full ROM with active and passive exam is found in adhesive capsulitis and arthropathy Evaluate bilaterally for comparison 25 Range of Motion Movement Forward flexion Extension (behind back) Abduction Adduction External rotation* Internal rotation* Normal range 180° 40° 180° (with palms up) 0° 45° (arm at side, elbow flexed) 55° (arm at side, elbow flexed) 26 Forward Flexion Arm straight and brought upward through frontal plane, and move as far as patient can go above his head 0° is defined as straight down at patient's side, & 180° is straight up 27 Abduction Arm straight Hand – palm up (arm supinated) ROM measured in degrees as for forward flexion 28 External and Internal Rotation Arm at side, elbow flexed to 90° and held at waist Examiner externally or internally rotates arm 29 Apley scratch test for ER/IR* External rotation and abduction Reach for upper scapula Compare bilaterally – note level reached Internal rotation and adduction Reach for lower scapula Compare bilaterally – note level reached 30 Strength Tests Flexion Extension 31 Strength Tests* External rotation Infraspinatus Teres minor Internal rotation Subscapularis 32 Strength tests Empty can test* Supraspinatus Lift off test* Subscapularis 33 Special Tests Rotator cuff Drop arm test Labral tear Impingement tests Neer’s sign Hawkin’s test Instability tests O’Brien’s test Crank test Anterior release Relocation test Speed’s test Biceps tendon 34 Rotator Cuff Empty Can Test Supraspinatus Lift off test Subscapularis integrity Drop Arm Test Rotator cuff tear or supraspinatus dysfunction 35 Drop Arm Test Purpose: tears in the rotator cuff, primarily supraspinatus muscle Method: patient abducts (or examiner passively abducts) arm and then slowly lowers it May be able to lower arm slowly to 90° (deltoid function) Arm will then drop to side if rotator cuff tear Positive test: patient unable to lower arm further with control If able to hold at 90º, pressure on wrist will cause arm to fall 36 Video of Drop Arm Test Click on image for video 37 Impingement - Neer’s Sign* Patient seated with arm at side, palm down (pronated) Examiner standing Examiner stabilizes scapula and raises the arm (between flexion and abduction) Positive test = pain 38 Video of Neer’s Sign Click on image for video 39 Impingement - Hawkin's Test* Patient standing Examiner forward flexes shoulder to 90°, then forcibly internally rotates the arm Positive test = pain in area of superior GH joint or AC joint 40 Video of Hawkin’s Test Click on image for video 41 Speed’s Test - Biceps tendon Forward flex shoulder against resistance while maintaining elbow in extension and forearm in supination Positive test = tender in bicipital groove (bicipital tendinitis) 42 Video of Speed’s Test Click on image for video 43 Labral Tear (SLAP) - O'Brien's Active Compression Test Patient standing Arm forward flexed 90°, adducted 15° to 20° with elbow straight Full internal rotation so thumb pointing down Examiner applies downward force on arm - patient resists Patient externally rotates arm so thumb pointing up Examiner applies downward force on arm - patient resists Positive test = Pain or painful clicking elicited with thumb down and decreased or eliminated with thumb up 44 Video of O’Brien’s Test Click on image for video 45 Labral Tear - Crank Test Shoulder elevated to 160° in the scapular plane A gentle axial load is applied through glenohumeral joint with one hand, while other hand does IR and ER Positive test = pain, catching, or clicking in the shoulder 46 Video of the Crank Test Click on image for video 47 Glenohumeral Joint Stability Anterior Glenohumeral Instability Apprehension test Relocation test Anterior release test 48 Apprehension Test - Sitting 90° of abduction Examiner applies slight anterior pressure to humerus and externally rotates arm Positive test = patient expresses apprehension 49 Apprehension Test Patient in supine position with affected shoulder at edge of table, arm abducted 90° Examiner externally rotates by pushing forearm posteriorly. Positive test = patient expresses apprehension 50 Relocation Test Performed after positive result on anterior apprehension test Patient supine Examiner applies posterior force on proximal humerus while externally rotating patient’s arm Positive test = patient expresses relief 51 Video of the Apprehension & Relocation Tests – Seated & Supine Click on image for video 52 Anterior Release Test Patient in supine position, arm abducted 90° Examiner performs Relocation Test, then releases downward pressure Positive test = patient expresses pain or instability when the humeral head is released 53 Video of Anterior Release Test Click on image for video 54 The Current Evidence Base for History Questions and Physical Exam Tests 55 Rotator Cuff Tear History / Maneuver Study Sens Spec Qual (%) (%) LR+ LR- PV+ PV(%) (%) History of trauma Night pain 2b 36 73 1.3 0.88 72 37 2b 88 20 1.1 0.6 70 43 Painful arc 2b 33 81 1.7 0.83 81 33 Empty can test 1b 84 89 50 58 1.7 2 0.22 0.28 36 98 22 93 Drop arm 1b 21 100 >25 0.79 100 32 56 Impingement / Instability Test Study Sens Spec LR+ LR- PV+ PVQual (%) (%) (%) (%) Impingement Hawkin’s 1b 87 89 60 2.2 0.18 71 83 Instability Relocation 2b 57 100 >25 0.43 100 73 2b 68 100 >25 0.32 100 78 Apprehension 57 AC / SLAP History / Maneuver Study Sens Spec LR+ LR- PV+ PVQual (%) (%) (%) (%) AC 1b 100 97 >25 0.01 89 100 Crank 2b 91 93 13 0.10 94 90 Active compression 1b 100 99 >25 0.01 95 100 Active compression SLAP 58 References Luime JJ, Verhagen AP, Miedema HS, et al.
