Osteochondritis dissecans of the shoulder and hip.

Shoulder and hip osteochondritis dissecans (OCD) are uncommon. Both glenoid and humeral head OCD are commonly associated with a traumatic etiology. Humeral head OCD can be treated with observation or drilling of the sclerotic margin for stable or unstable lesions. Glenoid OCD often presents with delamination of the articular cartilage and requires debridement and fixation of fragments. Hip OCD often involves the femoral head; yet, there are case reports of acetabular involvement. The etiology of femoral OCD is associated with other pathologies, and therefore may represent the sequelae of other disease processes. Hip lesions often require extensive surgical intervention.
