1/150. Chondromatosis of the ankle joint (Reichel syndrome). A case of chondromatosis of the upper ankle joint in childhood is described. It is a monoarticular disease with a good prognosis, frequently without known prior trauma or inflammation, although often free fragments of cartilage are seen in the joint cavities. It originates from the synovium of the joint, and is known in the literature as Reichel syndrome. ( info) |
2/150. Irreducible Galeazzi fracture-dislocation due to an avulsion fracture of the fovea of the ulna. We report a rare case of Galeazzi fracture-dislocation with an irreducible distal radioulnar joint. The cause of the irreducibility was entrapment of a fragment avulsed from the fovea of the ulna. The patient was successfully treated with open reduction and internal fixation of the radius, ulnar styloid process and avulsed fracture at the fovea of the ulna. ( info) |
3/150. Synovial chondromatosis of the subcoracoid bursa. Synovial chondromatosis, is the chondroid metaplasia of the synovial membrane. Large joints such as the knee and hip are most commonly involved. Extraarticular involvement is rarely described. Synovial chondromatosis may be associated with impingement syndrome of the shoulder. We report a case of synovial chondromatosis of the subcoracoid bursa, which resulted in impingement symptoms. ( info) |
| A 9-year-old boy with a rare localisation of synovial osteochondromatosis at the left sternoclavicular joint is presented. Synovial osteochondromatosis at this site and at this age has not been previously reported. joint loose bodies were removed surgically and partial synovectomy was performed. Follow-up showed no evidence of recurrence over a period of 8 years. ( info) |
5/150. Femoral head disintegration in a paraplegic patient: loose bodies in neuropathic joints. A case report of potential loose body formation in a hip joint of a paraplegic patient is presented. The case is used to discuss why loose bodies do not persist in neuropathic joints, although they might be expected to be common when this type of joint pathology exists. ( info) |
6/150. arthroscopy of the elbow for synovial chondromatosis. Two cases of arthroscopic removal of multiple loose bodies are presented. Successful results were achieved, and patients had 4-year follow-up. Both cases involved classic manifestations of synovial chondromatosis. Associated degenerative changes were present in one case; histologic examination could not confirm synovial origin of the disease. arthroscopy for removal of symptomatic loose bodies is an excellent choice as exemplified by these two cases. Care should be taken to review histologic findings, which may help in understanding the natural history of this type of process. ( info) |
| The authors present a case of pseudotumoral osteochondromatosis of the hip, interesting for its clinical and radiological features. They discuss the incidence of the sport in the pathogenesis of the loose bodies and the magnetic resonance findings. ( info) |
8/150. Irreducible acute anterior dislocation of the shoulder caused by interposed fragment of the anterior glenoid rim. Failure of manipulative reduction of acute anterior dislocation of the shoulder is extremely rare. A 55-year-old man dislocated his right shoulder when he fell heavily. Initial radiographs and computed tomographs demonstrated an anterior dislocation with fracture of the glenoid rim. Several attempts at closed reduction were unsuccessful. At the time of open reduction, the cause of failure was found to be interposition of a fragment of the anterior inferior glenoid rim in the joint. To prevent redislocation, the fragment was held in place by two Herbert mini bone screws after anatomic reduction, and the ruptured subscapularis was reattached to the lesser tuberosity. Two and a half months after surgery, the shoulder was stable with full range of motion. To the best of our knowledge, this is the first reported case of interposition of a fracture-fragment of the anterior inferior glenoid rim causing failure of reduction. ( info) |
9/150. A locked knee in extension: a complication of a degenerate knee with patella alta. We present a case of superior dislocation of the patella trapped by interlocked osteophytes. Unlike previous reports, in which the mechanism resulted from a blow to the inferior pole, it is postulated that increased load on the extensor mechanism, combined with patella alta and patellofemoral osteophytes, caused locking of the knee in extension.

10/150. Synovial chondromatosis of the shoulder. We describe a case of synovial chondromatosis involving the shoulder. Presenting symptoms, radiographic features, intraoperative findings, and treatment options are discussed. ( info) |
