Shoulder pain and the overhand athlete

There has been much controversy surrounding the issue of shoulder pain and the overhand athlete. Several hypotheses have been suggested as to the cause of the shoulder pain--subacromial impingement, anterior capsular laxity, internal or posterosuperior impingement, traction injury, and scapular imbalance. Treatment for the patient depends on the specific cause of the pain. As always, a full routine of nonoperative therapeutic measures should be administered before resorting to surgical intervention.
