Shoulder: Physical Exam

- See:
        - Diff Dx of Shoulder Pain
        - Shoulder Examination Tests (from

- History: (questions for modified Simple Shoulder Test);

- C-Spine:
    - r/o radiculopathy as well as axillary nerve hypaesthesia;
    - Spurling's manuever:
           - mechanical stress, such as excessive vertebral motion, may exacerbate symptoms;
           - gentle neck hyperextension w/ head tilted toward affected side will narrow size of neuroforamen and may exacerbate symptoms or produce radiculopathy;

- Shoulder Tenderness:
    - anterior capsule / biceps tendon;
    - AC joint;
    - posterior sulcus;

- ROM:
    - active and passive abduction of shoulder/scapular thoracic complex; 
          - see abductors of the shoulder
          - view from behind to note symmetry and possible winging of scapula;
          - combines glenohumeral and scapulothoracic motion;
          - be sure to have patient abduct the arm in the scapular plane (30-40 deg anterior to the coronal plane);
          - abduction should be measured with simultaneous maximal abduction of both arms, as the angle formed
                  by the humeral shaft and the midthoracic line;
          - functional evaluation:
                  - bring hand actively behind the neck with the elbow above the acromion;
                  - bring the elbow straight forward from that position, actively positioning the hand on top of the head with the elbow over the acromion;
                  - bring the elbow straight forward from that position, and fully elevate the arm from that position;
                  - the hand is not allowed to touch the head or neck during these functional movements;
          - references:
                  - The movements of shoulder joint.  A plea for use of 'plane of scapula' as plane of reference for movements occuring as humero-scapular joint. Johnson TB. Br J Surg. 1937;25:252-260.
    - IGHE: isolated glenohumeral elevation:
    - IR: internal rotation: (ability to touch thoracic spine);
          - loss of internal rotation may be especially common in throwing shoulders;
          - contracture of the posterior capsule will prevent the normal posterior translation/rotation when the arm is elevated;
                  - the result is superior elevation of the humeral head with elevation and accentuation of impingement; 
          - references:
                  - Reliability, Precision, Accuracy, and Validity of Posterior Shoulder Tightness Assessment in Overhead Athletes
                  - Posterior Capsular Contracture of the Shoulder 
                  - Quantification of Posterior Capsule Tightness and Motion Loss in Patients with Shoulder Impingement 
    - ER: external rotation: (both in adduction and abduction)
          - particular attention should be paid to external rotation a 0 and 90 deg of abduction;
          - loss of a small amount of external rotation can result in subacromial impingement, and this impingement prevents the greater tuberosity from rotating clear of the
                  acromion during arm elevation;
          - when there is more external rotation in the injured shoulder than the non injured shoulder, consider the diagnosis of subscapularis rupture; 
          - excessive ER with the arm at the side (rotation of >90 deg), may be an indicator of shoulder hyperlaxity and a risk factor for postoperative instability  
          - ref: Elbow Valgus Laxity May Result in an Overestimation of Apparent Shoulder External Rotation During Physical Examination

- Motor Exam:

    - trapezius
    - rhomboids
    - supraspinatus:
          - supraspinatus muscle is tested with the shoulder abducted 90 degrees, flexed 30 deg and then maximally internally rotated;
          - downward pressure is resisted primarily by the supraspinatus;
    - infraspinatus:
         - dropping sign:
                - tests power of external rotation at 0 deg of abduction;
                - patients forearm is placed in 45 deg of external rotation, and patient is asked to externally rotate against examiner's hand;
                - if the patient's arm falls back to 0 deg of external rotation then a positive test is recorded;
                - 100% sensitivity and 100% specificity for irreparable degeneration of the infraspinatus;
    - teres minor:
         - responsible for 45% of power of external rotation;
         - hornblower's sign:
                - power of external rotation in 90 deg of abduction in the scapular plane;
                - the examiner places the patient's forearm in 90 deg flexion w/ maximal external rotation;
                - the examiner's other hand is used to judge external rotation force;
                - when the examiner's hand is released a positive test is recorded if the patient is unable to externally rotate;
                - 100% sensitivity and 93% specificity for irreparable degeneration of teres minor;
    - subscapularis
         - positive lift-off test:
                - indicates a tear of the subscapularis   
                - patient is unable to lift the hand away from his back while maximally internally rotated
                - ref: Diagnostic value of four clinical tests for the evaluation of subscapularis integrity
    - deltoid:
    - biceps:
    - reference:
         - The 'dropping' and 'hornblower's' signs in evaluation of rotator cuff tears.

- Impingement and Rotator Cuff Test:
    - impingement sign and test
    - drop arm test: for rotator cuff tears;
           - have the patient abduct his arm to 90 degrees and then ask him to lower his arm to his side slowly while the examiner applies gentle pressure;
           - at approximately 30 deg of abduction, the patient will no longer be able to gradually lower his arm and it will fall to his side;
    - AC joint:
           - arm is placed into forced adduction while surgeon palpates AC joint and notes any possible instability and or tenderness;
           - note that posterior tenderness from hyper-adduction of the shoulder may result from posterior capsular tenderness;

- Tests for Instability:
    - sulcus sign: (for multidirectional instability)
           - a gap between the humeral head and undersurface of the acromion;
           - appears when the longitudinal traction is placed on the humeral shaft w/ arm at side while in a seated position;
           - the sulcus sign is felt to be pathognomonic of multidirectional instability;
           - upto 1 cm of displacement may be normal, where as displacement of 3 cm is severe;

    - exam for anterior instability:
           - rotatory stress test:
                  - for determining presence of Bankart Lesion
    - posterior instability:
           - jerk test: pt's arm is abducted to 90 deg and internally rotated;
                  - the examiner axilly loads the humerus while the arm is moved horizontally across the body
                          - the left hand stabilizes the scapula;
                  - look for a sudden jerk as the humeral head slides off the back of glenoid;

                          - Painful jerk test: a predictor of success in nonoperative treatment of posteroinferior instability of the shoulder.

    - SLAP tear:
         - speed's test:
              - used to examine the proximal tendon of the long head of the biceps
              - forward flex the shoulder (60 deg) against resistance while maintaining the elbow in extension and the forearm in supination
              - tenderness in the bicipital groove in dicates bicipital tendinitis
         - obrien's test
              - shoulder is held in 90 degrees of forward flexion, 30 to 45 degrees of horizontal adduction and maximal internal rotation;
              - grab the patient's wrist and resists the patient's attempt to horizontally adduct and forward flex the shoulder
