CASE: A 19-year-old college baseball outfielder presented with a 3-month history of right shoulder pain. Radiographs, computed tomography, and magnetic resonance imaging showed a large osteochondral defect at the posterosuperior aspect of the glenoid. Arthroscopic evaluation identified an unstable fragment that was partially attached. Fixation of the osteochondral fragment was achieved with autogenous osteochondral plugs through a posterior arthrotomy. At 8 months after surgery, the patient was able to return to his former competitive level of performance. CONCLUSION: Osteochondritis dissecans (OCD) rarely affects the glenoid. Fixation of a large glenoid OCD lesion with autogenous osteochondral plugs was a successful treatment in this patient.
