Atraumatic osteolysis of the distal clavicle: histologic evidence of synovial pathogenesis. A case report

Orthopedics. 1986 Apr;9(4):557-9. doi: 10.3928/0147-7447-19860401-15.


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.
