Gerber Lift-off Test

1) With patient standing or supine (for acute or chronic dislocations), place patients arm in 90 degrees abduction, with elbow flexed to 90 degrees 2) Gently externally rotate humerus to 90 degrees 3) Patients with anterior instability may be apprehensive in this position because of the sense of impending dislocation 4) Pain with apprehension is less specific

Apprehension Sign for Anterior instability

1) With patient supine, place patients arm in 90 degrees abduction, with elbow flexed to 90 degrees, and 90 degrees of external rotation 2) Apply posterior force to the anterior proximal humerus at point of external rotation when patient feels apprehensive 3) This should precent anterior subluxation 4) Test is positive if relief of pain and apprehension occurs 5) Suggests anterior glenohumeral instability

Relocation Test of Jobe

1) With patient's arm relaxed to side place one hand on the posterior scapula and use the other hand to apply traction to the patient's arm in an inferior direction 2) This maneuver will cause inferior subluxation of the humeral head and a widening of the sulcus between the humerus and acromion 3) A visible dimple is a positive sulcus sign 4) A positive sulcus suggest that the patient has inferior shoulder instability

Sulcus Sign

1) Place the patient's arm in 90 degrees of flexion with maximal internal rotation with the elbow flexed at 90 degrees 2) Adduct the arm cross body in the horizontal plane while applying an axial load at the elbow to push the humerus in a posterior direction 3) If the maneuver causes a posterior subluxation or dislocation, the humeral head can be felt to clunk or jerk back into the joint as the arm is then horizontally abducted

Jerk Test

1) Flex patients shoulder to 90 degrees and then horizontally adduct the arm across the body 2) Pain over the acromioclavicular joint pathology

Cross Body or Horizontal Adduction Test

1) Place the patient’s arm in flexion 90 degrees of flexion, horizontally adduct to 20-30 degrees. 2) Have patient point thumb down, apply downward force against resistance. 3) Apply force again, but with forearm supinated. 4) Positive: Pain is worse with thumbs down, relieved with forearm supinated. Suggest labral pathology.
