As Shill indicates, here is an article (one of the first I ever did on ptupdate)
OSTEOLYSIS OF THE DISTAL CLAVICLE. The Physician and Sportsmedicine, Vol. 28, No. 12, December 2000.

ABSTRACT
Osteolysis of the distal clavicle occurs when resorption of the bone occurs, usually due to traumatic causes (a blow to the shoulder), or atraumatic causes (usually weightlifting in males, but also seen in air-hammer operators, judo artist, and handball player). Patients usually complain of a dull ache localized over the AC joint, but may radiate into the trapezius or deltoid. Night pain is rare, but sleeping on the involved side may cause pain. For weight lifters, pain usually occurs on bench pressing, dips, and push-ups. The AC joint is point tender, and cross body adduction will elicit pain. The patient may have full AROM, but may have pain on impingement tests. Differential diagnosis includes: AC joint pathology/arthritis/separation, rotator cuff problems, RA, instability, labral tears, and steroid arthropathy. Initial radiographs may not show a problem early on, but later, after months or years, show a loss of subchondral bone. Etiology may include vascular compromise, microfractures, and stress-induced osteoclastic resorption. Treatment consists of activity modification, or when that is not possible, distal resection of the clavicle. Injection may offer short-term relief, but no studies have been done to determine long-term effects. PT is not used unless there is a concomitant pathology in the shoulder. Symptoms usually return if the patient resumes the activities that cause pain.
