1/7. Arthroscopic treatment for synovial chondromatosis of the shoulder.

    Synovial chondromatosis of the shoulder is a rare condition. The following is a description of such a case with the presenting symptoms, radiographic features, intraoperative findings, and the arthroscopic technique for treatment of this disease. Loose bodies were found in the long head of the biceps tendon sheath, the subscapularis recess, and throughout the glenohumeral joint, causing erosive damage. We feel that arthroscopy allows for better visualization of the entire glenohumeral joint, including the long head of the biceps tendon sheath and the subscapularis recess, and for ease of loose body removal. Additional advantages of arthroscopy include decreased postoperative pain, early active range of motion, shorter course of rehabilitation, and earlier functional return.

2/7. Rocky form giant synovial chondromatosis: a case report.

    We report a case of painless synovial chondromatosis with an extremely large mass at the popliteal area related to the right knee joint. A hard mass at the posterior aspect of the knee was the only complaint reported by the patient. Plain X-ray studies revealed punctuated calcifications both intra-articularly and around the knee joint. With the surgical procedure performed subsequently, multiple rocky-hard giant chondroid nodules were excised from the posterior aspect of the knee. After 9 months following the surgery, the patient had full range of motion, and no complaints. We emphasize on the importance this case because these lesions may simulate tumors, and lead to misdiagnosis.

3/7. Rice-body formation and tenosynovitis of the wrist: a case report.

    A 61-year-old woman presented with mild pain and swelling on the volar aspect of the wrist, hand, and little finger. radiography showed a soft-tissue mass shadow, and magnetic resonance imaging showed acute tenosynovitis of the flexor tendons and an inflammatory mass inside the carpal tunnel. Laboratory test results were normal, except for an elevated erythrocyte sedimentation rate (40 mm/h). The patient had an ambiguous Mantoux test result but no history of mycobacterial exposure. Exhaustive investigations for rheumatic disease were negative. Surgical exploration of the lesion revealed rice bodies in the common flexor tendon synovial sheath, extending distally to the tip of the fifth finger. Removal of the rice bodies and thorough excision of the sheath was performed. The patient regained a full and painless range of motion in about 3 months. One-year follow-up revealed no underlying disorder.

4/7. shoulder rheumatoid arthritis associated with chondromatosis, treated by arthroscopy.

    We present a case of rheumatoid arthritis that affected the right shoulder and was associated with chondromatosis and multiple loose body formation. The arthritis was treated arthroscopically with satisfactory results after a follow-up period of 15 months. In our case, arthroscopic debridement and partial synovectomy not only relieved the pain but also improved the range of motion the night after surgery. The multiple loose bodies irritating the synovium and causing effusion, crepitus, and locking were also removed. One may need to change portals of the scope and suction cannula to remove loose bodies in different joint spaces. The subacromial space must be searched for loose bodies. Thorough cleaning, lavage, and synovectomy are important parts of this surgery. The continuous passive motion (CPM) machine in the immediate postoperative period was helpful.

5/7. Reconstruction of the triangular fibrocartilage complex after surgery for treatment of synovial osteochondromatosis of the distal radioulnar joint.

    Synovial osteochondromatosis of the hand is uncommon, except for tenosynovial chondromatosis of the digits. It is even more rare in the wrist joint. A patient with synovial osteochondromatosis of the distal radioulnar joint that involved the triangular fibrocartilage complex is described. At operation, synovectomy, excision of osteochondral bodies, and removal of the entire triangular fibrocartilage complex was done. The triangular fibrocartilage complex was reconstructed using part of the extensor carpi ulnaris tendon. One year after operation, the patient had regained almost full range of motion and is without pain.

6/7. Synovial chondromatosis of the temporomandibular joint: report of two cases.

    Two cases of synovial chondromatosis of the temporomandibular joint are reported. This condition is rare but benign, with only 36 cases reported in the literature to date. Symptoms include tenderness, swelling, and limited range of motion, with deviation to the affected side. diagnosis is made both from the clinical presentation and histologic examination. The etiology is thought to be cartilaginous foci within the synovial membrane that become detached and proliferate in the synovium as chondrocytes. Treatment includes removal of the "loose bodies" and possible resection of the synovial membrane, condyle, and disk.

7/7. Synovial osteochondromatosis of the elbow presenting with ulnar nerve neuropathy.

    Synovial chondromatosis is an uncommon disorder in which cartilaginous material is formed within synovial tissue. The cartilaginous nodules may undergo enchondral ossification, described as synovial osteochondromatosis. The nodules may be shed from the synovium and become intra-articular loose bodies. The presenting symptoms are usually diffuse discomfort in the affected joint and decreased range of motion with an accompanying gritty or locking sensation. The authors present the case of a young man with elbow synovial osteochondromatosis associated with ulnar nerve neuropathy.
