Abstract:
Osteolysis of the distal clavicle was diagnosed in a young male athlete following many years as a baseball pitcher with a supplementary weightlifting program. There was no history of ligamentous injuries, contusions, fractures or separation of the acromioclavicular joint. As such, this case was categorized as "atraumatic" osteolysis. Non-decalcified histologic sections from the resected clavicle suggest that the pathogenesis of this atraumatic osteolysis arose from the synovium.
