We reported on a rare case of synovial osteochondromatosis (SOC) of the shoulder with a severe degenerative glenohumeral arthrosis. The patient was a 24-year-old female who complained of pain and a subluxaition feeling in her left shoulder. She had experienced difficulty in left shoulder elevation for about 10 years, however no abnormalities had been pointed out on X-ray. She visited our clinic after having had 5 subluxation feelings without any trauma over the last 4 years. The active range of motion was 80o-forward elevation, 15o-external rotation, and the internal rotation was at a level of Th10. TT The X-rays showed intraarticular spotty ossification and severe glenohumeral arthrosis. Arthrography showed multiple loose bodies in the capsule. At a time of 7-year-follow-up after an operation, the range of motion was slightly limited, but she had no pain in the shoulder. The irregularities of the subchondral bone of humerus had improved on X-rays. SOC with severe glenohumeral arthrosis is rarely reported. This case was not a primary, but a secondary SOC with some underlying disease considering the histological findings.
