Lesions of the biceps and tendinitis of the shoulder.

It is of utmost importance to establish a proper diagnosis through physical examination and especially by use of arthrography of the shoulder. The latter is the most definitive means of eliminating the possibility of a tear of the rotator cuff or of recurrent anterior glenohumeral subluxation as the cause of the patient's symptoms. After the correct diagnosis is made, a nonoperative approach can be useful in many cases. If this is unsuccessful or if the biceps is subluxating or dislocating, a successful operation is available to alleviate the problem.
