Osteochondritis dissecans with associated secondary chondromatosis in an adolescent shoulder.

Osteochondritis dissecans (OCD) of the humeral head is rare and usually occurs in adolescents. Secondary synovial chondromatosis occasionally occurs in the shoulder but has only been reported twice in an adolescent. We describe the case and management of an adolescent male who presented with features of OCD and secondary chondromatosis in his shoulder occurring simultaneously.
