PTA 130 Fundamentals of Treatment I The Shoulder and Shoulder Girdle Lesson Objectives Identify key anatomical muscles and structures of the shoulder and arm. Identify common tissue injuries, conditions and surgical interventions. Analyze restorative interventions for common injuries. Identify soft tissue specific mobilizations for the shoulder and arm. Identify flexibility and ROM exercises. Shoulder Factors The shoulder girdle allows for mobility of the upper extremity in multiplanar directions One of the primary functions of the shoulder is to position the hand The shoulder girdle only has one bony attachment to the axial skeleton Can you name the joint? High injury risk because major shoulder stabilization comes from muscle strength and coordination Shoulder Anatomy Review Joints of the Shoulder Girdle Complex The clavicle articulates with the sternum at the sternoclavicular joint Stability is provided by muscles and joints Three synovial joints: Glenohumeral Acromioclavicular Sternoclavicular Two functional articulations: Scapulothoracic Suprahumeral (subacromial space) Shoulder Stability Structural stability provided by: Ligaments Capsule Glenoid labrum Dynamic stability provided by: Muscular strength Neuromuscular control Proprioceptive input Skilled motor response Concorde Career College Scapulothoracic Articulation Motions of the Scapula: Elevation and depression Protraction and retraction Upward and downward rotation • What motion happens with flexion of the humerus? Winging and tipping Scapular Stability Scapular muscle stabilizers Rhomboid major and minor Serratus anterior Middle and lower trapezius Scapular stability provides platform for the glenohumeral (GH) joint Poor scapular stabilization => unstable GH base Concorde Career College Scapulohumeral Rhythm Describes the timing of movement at these joints during shoulder elevation First 60 degrees of shoulder elevation and/or 30 degrees of shoulder ABDuction involves a "setting phase": The movement is primarily at the GH joint Scapulothoracic movement is small and inconsistent During the mid-range of humeral motion: The scapula has greater motion Typically at 1:1 ration with the humerus The GH joint dominates the motion in end ranges Scapulohumeral Rhythm Scapulohumeral rhythm serves at least two purposes. It preserves the length-tension relationships of the muscles moving the humerus It prevents impingement between the humerus and the acromion Referred Pain Cervical Spine – Vertebral joints between C3, C4, C5 Nerve Roots C4 or C5 Diaphragm Pain perceived in the upper traps region Heart Pain perceived in the axilla and left pectoral region Gallbladder irritation Pain perceived at the tip of shoulder Nerve Injury Brachial Plexus in the thoracic outlet Compression of the brachial plexus nerves may occur under the coracoid process and pect minor Suprascapular nerve compression Direct compression or nerve stretch May occur when carrying a heavy bag over the shoulder Radial nerve compression Continual pressure in axilla Leaning on axillary crutches What motions occur at the scapula while in this posture? Concorde Career College Posture in Relationship to Shoulder Correct posture is crucial to shoulder balance and function Forward-head posture Round shoulder, rotator cuff impingement, and shoulder flexion ROM Scapula assumes protracted and anteriorly tilted posture • Causes internal rotation (IR) of GH joint • Tightness in anterior chest muscles • Weakness of posterior thoracic spine musculature Concorde Career College Shoulder Joint Hypomobility Restricted mobility at the glenohumeral (GH) joint may occur as a result of: RA, OA Traumatic arthritis Prolonged immobilization Idiopathic frozen shoulder (adhesive capsulitis) Acromioclavicular Joint (AC) Sternoclavicular Joint (SC) AC and SC joints may become hypomobile due to arthritis, faulty postures, fractures, or dislocations Common Shoulder Injuries Rotator Cuff Tear Rotator Cuff Tendonitis Shoulder Impingement Shoulder Bursitis Shoulder Arthritis Frozen Shoulder Shoulder Dislocation or Separation Bicep Tendonitis Shoulder Instability Labral tears, SLAP lesion, Bankart repair Acromioclavicular Sprain Rotator Cuff Tear Commonly occur in both athletic and nonathletic patients Symptoms include pain, weakness, and decreased range of motion Early diagnosis is important for identifying causes, implementing effective treatment, and preventing further injury The supraspinatus is the most commonly injured/torn rotator cuff muscle Rotator Cuff 4 muscles and their tendons: Supraspinatus muscle; Shoulder ABDuction Infraspinatus muscle; Shoulder External Rotation Teres minor muscle; Shoulder External Rotation Subscapularis muscle; Shoulder Internal Rotation Rotator Cuff Tear Stage 1 Partial tear less than 1 cm in size Stage 2 Partial tear > 1 cm, but < 5 cm in size Stage 3 Full tear greater than 5 cm Treatment: Stretching/ROM, isometrics, modalities, surgical intervention (if necessary) Rotator Cuff Tendonitis The most common rotator cuff injury Caused by chronic overuse Commonly occurs in the supraspinatus and infraspinatus tendons Patient will most likely complain of pain with overhead motions Patient will have pain with palpation over the tendon Treatment: Stretch/ROM, isometrics, Cross-Friction massage, and modalities Shoulder Impingement Occurs as a result of mechanical wear of the rotator cuff against the anteroinferior aspect of the acromion in the suprahumeral space Vascular changes in the rotator cuff tendons and structural variations in the acromion often accompany this diagnosis Faulty posture may also lead to shoulder impingement Treatment: Stretching, Soft tissue mobilization, Modalities, and possible surgical intervention Shoulder Bursitis Inflammation of the subacromial bursa May be caused by overuse of the shoulder and/or repetitive activities Treatment: Rest, Stretching, Soft tissue mobilization and Modalities GH Joint Arthritis Acute Phase Patient will present with pain and muscle guarding ER and ABDuction are most limited Subacute Phase Patient will present with capsular tightness Pain is elicited when shoulder is moved into end ranges Chronic Phase Progressive GH joint restriction Significant loss of function Frozen Shoulder (Adhesive Capsulitis) Characterized by the development of adhesions, capsular thickening, and capsular restrictions Onset may be insidious Cause is idiopathic Contributing factors may be: pain, restricted motion, arthritis, immobilization, trauma, etc. Follows a pattern: “Freezing” “Frozen” “Thawing” Frozen Shoulder (Adhesive Capsulitis) Common Impairments: Night pain and disturbed sleep Pain with motion Decreased mobility Muscle weakness Substitution patterns Functional limitations Treatment: Prevention, Stretch/ROM, joint mobilization, strengthening, and modalities Shoulder Dislocation The GH joint is the most commonly dislocated joint in the body Usually caused by a severe blow to the arm with arm held in a position of external rotation and abduction Anterior dislocations occur most frequently Closed reduction Skilled technique to reduce the dislocation Protection Phase, activity restriction for 6-8 weeks Avoid position of dislocation Protected ROM, isometrics Shoulder Dislocation Controlled motion phase Increase mobility Increase stability and strength of RC and periscapular muscles Return to function phase Restore functional control; balance strength of shoulder and scapular musculature Coordination Endurance Eccentric training Increase speed and control Simulate functional patterns Bicipital Tendinitis Lesion is typically located on the long head of the biceps tendon in the bicipital groove Pain is elicited with resisted shoulder flexion while the arm is supinated Tenderness to palpation of the bicipital groove Treatment: Isometric exercises, Stretching, Cross-Friction massage, and modalities Shoulder Instability Multidirectional Instability Individuals have lax connective tissue which allows for mobility The humeral head will translate to a greater degree than normal in all directions Individuals involved in overhead throwing or lifting activities may be more prone to develop laxity of the shoulder capsule Hypermobility may also lead to impingement, subluxation, dislocation, or tendinitis Multi-directional Instability Unidirectional Instability May occur in one of the following directions: Anterior Posterior Inferior Usually the result of trauma Typically involves rotator cuff tears Damage to the glenoid labrum is also common Shoulder Instability AMBRI: Atraumatic, Multidirectional, often Bilateral, requires Rehabilitation, Inferior capsular shift is the best alternative surgical therapy Usually initiated without trauma Often multidirectional (anterior, inferior and posterior) Occurring in patients with generalized joint laxity Shoulder Instability AMBRI Usually does not have surgery Treatment consists of a program of shoulder strengthening and stabilization exercises Shoulder Instability TUBS (Traumatic, Unidirectional, Bankart, Surgery) One of most common shoulder injuries in athletes • Most common in contact athletes May present as traumatic dislocation/subluxation Mechanism is a posteriorly directed force on an abducted and externally rotated arm High recurrence rate that correlates directly with age at dislocation • Up to 80-90% in teenagers Traumatic Shoulder Dislocation Glenoid Labral Tear - CAUSES Falling on an outstretched arm A direct blow to the shoulder A sudden pull, such as when trying to lift a heavy object A violent overhead reach May occur while trying to stop a fall or slide Throwing athletes or weightlifters may experience glenoid labrum tears as a result of repetitive shoulder motion Labral Tear SLAP Lesion Tear of the superior labrum SLAP (Superior Labrum extending Anterior to Posterior) Often associated with a tear of the proximal attachment of the long head of the biceps and recurrent anterior instability of the GH joint Surgery involves debridement of the superior labrum and reattachment of the labrum and biceps tendon Bankart Repair Bankart Lesion Detachment of the capsulolabral complex from the anterior rim of the glenoid Commonly occurs as a result of a traumatic anterior dislocation The repair involves an anterior capsulolabral reconstruction to reattach the labrum to the surface of the glenoid lip Acromioclavicular Sprain Most AC sprains are NOT surgically repaired Sometimes requires initial immobilization Modalities used to relieve pain, swelling and muscle spasms Early active and AAROM exercises to regain and maintain mobility Isometric strengthening exercises A-C Sprain / Dislocation Common Surgical Procedures Glenohumeral Arthroplasty Arthrodesis of the Shoulder RCR- Rotator Cuff Repair SAD- Subacromial Decompression Glenohumeral Arthroplasty Total shoulder arthroplasty (TSA) The glenoid and humeral surfaces are replaced Hemireplacement arthroplasty The humeral head is replaced Both are open surgical procedures Indications for surgery: Persistent and incapacitating pain Loss of shoulder mobility or stability Inability to perform functional tasks TSA Postoperative Management Progression is influenced by the integrity of the rotator cuff musculature Shoulder is typically immobilized Maximum Protection Phase: Day 1 post-op -> 6 weeks post-op Control of pain and inflammation Maintain mobility of adjacent joints Restore shoulder mobility Minimize muscle guarding and atrophy TSA Postoperative Management Moderate Protection/Controlled Motion Phase 6 weeks -> 12-16 weeks post-op Continue to increase PROM of the shoulder Develop active control and dynamic stability Improve muscle performance (strength and endurance) TSA Postoperative Management Minimum Protection/Return to Functional Activity Phase Begins around 12-16 weeks post-op Extends for several more months Continue to improve or maintain shoulder mobility Continue to improve active control of the shoulder Progress muscle strengthening and stabilization exercises Return to functional activities Arthrodesis of the Shoulder The GH joint is fused with pins and bone grafts Indications for surgery Incapacitating pain Gross instability of the GH joint Complete paralysis of the deltoid and rotator cuff muscles Severe joint destruction due to infection Failed TSA Arthrodesis of the Shoulder Postoperative Management Emphasis is placed on maintaining mobility of peripheral joints (wrist and hand) while the shoulder and elbow are immobilized Following immobilization, begin active scapulothoracic ROM Rotator Cuff Repair May be appropriate for either partial-thickness tears or full-thickness tears Indications for surgical repair are: Pain Impaired function Surgical repair is not indicated for patients who are asymptomatic despite imaging reports confirming presence of a cuff tear Surgical approach may be arthroscopic or open Rotator Cuff Repair Postoperative management depends upon many factors: Size and location of tear Onset of injury Preoperative functional mobility and strength Age of patient Type of approach Type of repair RCR Postoperative Management Maximum Protection Phase (up to 8 weeks) Patient will most likely be immobilized Protection of the repaired tendon(s) is the primary goal during this phase Control pain and inflammation AAROM exercises for elbow AROM exercises for wrist and hand Prevent shoulder stiffness Restore shoulder mobility Posture re-education Scapular stabilization exercises Gentle isometrics for GH joint musculature RCR Postoperative Management Moderate Protection Phase Restore nearly full, nonpainful, passive mobility of the shoulder Increase muscular strength and endurance of shoulder musculature Re-establish dynamic stability of the shoulder AROM is allowed in pain free ranges Strengthening typically begins around 8 weeks postop, but may begin as late as 12 weeks for larger repairs RCR Postoperative Management Minimum Protection/Return to Function Phase Begins around 12-16 weeks post-op, and lasts for 6 months to a year Continue to work towards full ROM • Passive stretching of GH musculature • Joint mobilization Advance task-specific exercises Patients are not allowed to return to high demand activities for 6 months, up to 1 year Subacromial Decompression Designed to increase the volume of subacromial space and provide adequate gliding room for tendons Indications for surgery: • Pain during overhead activities • Loss of shoulder functional mobility • Intact or minor rotator cuff tear • Impingement Performed using an arthroscopic or open approach Subacromial Decompression Maximum Protection Phase (0-4 weeks) Patient will have shoulder immobilized for 1-2 weeks Pain control and inflammation control ROM activities (PROM, AAROM, AROM) Patient education Postural re-education exercises Isometric exercises Subacromial Decompression Moderate Protection Phase (4-8 weeks) Joint mobilization Stretching Postural re-education Isotonic strengthening exercises Functional activities with light resistance Minimum Protection Phase (8 weeks – 6 months) Continued strengthening
