Shoulder Pathology and Examination For Finals Sarah White FY1 RLBUHT To be covered • Anatomy • Common pathology • Examination • MCQs Anatomy- Bones Anatomy- Muscles • Rotator cuff (SITS): • Supraspinatus • Infraspinatus • Teres minor • Subscapularis Anatomy- Nerves Pathology- Arthritis • Osteoarthritis most likely to affect shoulder • Acromioclavicular joint >glenohumeral • Symptoms: • Pain • Stiffness • Reduced range of movement • Rheumatoid arthritis in shoulder uncommon • Septic arthritis possible • Avascular necrosis • Causes • Trauma • Sickle cell disease LOSS Vs. LESS LOSS • • • • Loss of bone space Osteophytes Subchondral sclerosis Subchondral cysts LESS • • • • Loss of joint space Erosions Soft tissue swelling Soft bones (osteopenia) Pathology- Dislocation • • • • Aetiology • Traumatic • (Rare: connective tissue disorders i.e. Ehlers Danlos) Presentation • Symptoms: pain, inability to move joint, tenderness, swelling • Examination: classical posturing of slight abduction and external rotation (anterior dislocation=95%) Management • Analgesia • Rule out fracture • Reduce dislocation Higher risk for future dislocation, joint instability Pathology- Impingement Syndrome • Clinical sign not a diagnosis • Aetiology • • Presentation • • Repetitive pinching of supraspinatus tendon as it passes through subchromial space causing irritation and inflammation- supraspinatus tendonitis Painful arc Management • Rest and ice • NSAIDS • Steroids injected in subchromial space Pathology- Rotator Cuff Tear • • • Aetiology • Atraumatic in older patients, attrition from bony spurs • Traumatic in younger patients Presentation • Pain • Restricted mobility in pattern dependent on which muscle is torn- special tests to isolate muscles Management • Rehab and NSAIDS • Surgical repair • Physiotherapy Pathology- Frozen Shoulder • AKA adhesive capsulitis • Aetiology • • • Spontaneous • Following rotator cuff injury • Following period of immobility i.e. CVA or plaster immobilisation Presentation • Non-dominant shoulder more often affected • Pain followed by stiffness • Restriction of all shoulder movements both active and passive Management • Difficult. • Analgesia • Physio • Corticosteroid injections Pathology- Long thoracic nerve injury • • • Aetiology • Trauma to ribs • Damage during surgery i.e. radical mastectomy Presentation • Winged scapula • Shoulder pain Management • Physio • Surgical repair of nerve Examination • Explanation and consent • Inspection • Palpation • Movement: active and passive • Special tests • Neurovascular integrity • Concluding remarks Examination- Explanation and Consent • Introduce self • What examination you want to do • Why you want to do it • What the examination involves • Chaperone • Gain consent Examination- Inspection • From front/side/back • Compare side to side for: • • Symmetry • Muscle wasting • Scars • Erythema • Swelling Check for long thoracic nerve injury • Ask pt to stand, face wall, place hands on wall at shoulder height to illicit winged scapula Examination- Palpation • Temperature, compare side to side • Bony anatomy • Sternoclavicular joint • Clavicle • Acromioclavicular joint • Head of humerus • Spine of scapula What are you feeling for: • warmth • tenderness • loss of bony continuity • bony abnormality (osteophytes) Examination- Movement • Active range of movement, both shoulders at once to compare side to side. • From side • • Flexion (180 degrees) • Extension (60 degrees) • External rotation (70 degrees) From back • Internal rotation (reach up back) • Abduction (180) • Adduction (180) • Repeat all movements passively, hand on shoulder feel for crepitus. • Slow abduction for painful arc (impingement syndrome, pain at 60-120 degrees) Examination- Functional Movement • Both hands behind head- washing hair, dressing • Both hands up to mouth- eating • Both hands down to bottom- cleaning after toilet Examination- Special Tests • Shoulder apprehension test- for shoulder instability • Young patients • Pt lies supine • Abduct shoulder to 90 degrees • Flex elbow 90 degrees • Externally rotate shoulder by holding humerus and pushing pt’s hand up • Positive test- pt is “apprehensive”, feels like shoulder will dislocate • https://www.youtube.com/watch?v=_JA-qvXcUdQ Examination- Special Tests • Hawkin’s test- Impingement syndrome • Middle aged patients • Flex shoulder 90 degrees • Flex elbow 90 degrees • Passive internal rotation- stabilise humerus and push down hand • Positive test- pain in shoulder • https://www.youtube.com/watch?v=OYK5qL2om-c Examination- Special Tests • Jobe’s test (empty can)- rotator cuff injury/tear SUPRASPINATUS • Older patients • Straight arm abducted to 90 degrees, angle forwards by 30 degrees, fist with thumbs down • Force adduction, ask pt to resist you • Positive test- pain/difficulty with resistance • May also be positive in impingement syndrome • https://www.youtube.com/watch?v=cuVWk09sk3k Examination- Special Tests • Gerber’s lift off test- rotator cuff injury/tear SUBSCAPULARIS • Older patients • Stand behind pt, ask pt to put dorsum of hand on mid lumbar spine • Apply some pressure to pt’s palm • Ask pt to push hand away from spine • Positive test- pain or difficulty • https://www.youtube.com/watch?v=__jgMNMQIQU Examination- Special Tests • Resisted external rotation- rotator cuff injury/tear TERES MINOR AND INFRASPINATUS • Older patients • • Arms by side • Elbows flexed to 90 degrees • Ask pt to externally rotate shoulders against resistance Positive test- pain or difficulty Examination- Neurovascular • • Sensation • Axillary- regimental badge • Median- lateral aspect index finger • Ulnar- medial aspect little finger • Radial- dorsal 1st interosseous space Vascular • Radial pulse • CRT in finger Examination- Concluding remarks • Examine other shoulder to compare • Joint above and below (neck, elbow) • Investigations • X ray (AP, modified axillary view) • MRI • Joint aspiration MCQ • 1- Which direction is the shoulder most likely to dislocate in? • a) Superior • b) Inferior • c) Anterior • d) Posterior MCQ • 2- Which muscle of the rotator cuff is implicated in impingement syndrome? • a) Supraspinatus • b) Infraspinatus • c) Teres minor • d) Subscapularis MCQ • 3- Which nerve is implicated in winged scapula? • a) Long thoracic nerve • b) Axillary • c) Ulnar • d) Radial MCQ • 4- Which nerve is most vulnerable to damage as a complication of anterior shoulder dislocation? • a) Long thoracic nerve • b) Axillary • c) Ulnar • d) Radial
