Tennis shoulder

Abstract

A depression of the exercised shoulder was found in skilled tennis players, and in other athletes employing the overhand motion. The deformity is attributed to stretching of the shoulder elevating muscles and hypertrophy of the extremity. Most symptoms were over the anterior rotator cuff, and occurred on abduction of the arm. Shoulder depression results in a relative abduction and abduction causes impingement of the cuff. Shoulder droop may induce thoracic outlet syndrome and may simulate scoliosis in the athlete.
