Osteochondritis dissecans (OCD) of the shoulder glenoid fossa is rarely diagnosed. The aim of this study is to report two cases of OCD of the glenoid. The patients were a 14-year-old and a17-year-old school baseball players. Although there was no history of shoulder injury, both felt shoulder pain when throwing. MRI and CT findings showed osteochondritis dissecans (OCD) lesion of the glenoid. One of the two cases was treated conservatively, and the other had surgical treatment.<BR>Physical examinations in the first case were mostly improved by physical therapy, but the glenoid lesion in CT was not recovered completely after no throwing for 4 months. Although he was able to pitch, we recommended him to change the position to fielder.<BR>MRI of the second case showed superior labrum lesion, cyst of suprascapular notch and OCD of the glenoid. This case did not responded well to physical therapy, and thus we performed arthroscopic surgery. Arthroscopic findings revealed softened glenoid surface covered by intact cartilage (international cartilage repair society, OCD stage I). We debrided torn labrum, decompressed a cyst and applied drilling to the softened area of the glenoid. Physical findings were mostly improved immediately after surgery. Three months after the operation, MRI showed no cystic lesion and improved osteochondral lesion, he also returned to pitching gradually.<BR>Some similar cases have been reported however the treatment methods for OCD lesion were inconsistent. Optimal treatment in each case is still unclear, thus continuous follow-up is necessary to assess late pathologic changes around the lesion.
