Summary:Synovial osteochondromatosis is a benign disease of synovial tissue, most commonly affecting the knee and elbow joint, and is rarely found in the hip joint. We report two cases of synovial osteochondromatosis of the hip joint. In both patients, motion of the affected hip joint was not greatly restricted. Roentgenography of the affected hip joint revealed expansion of the joint cavity. Arthrogrphy of the involved hip joint showed a honeycomb shadow. Definite diagnosis was made on the arthrographic findings in both cases. We performed arthrotomy, taking care not to dislocate the femoral head because of the potential hazard of femoral head necrosis. Many loose bodies and synovial tissue were removed in both cases. Postoperatively, both patients did well.
