A case report. Chondromatosis of the temporomandibular joint.

Synovial chondromatosis is a rare pathological condition that usually affects large joints but can affect the temporomandibular joint. The disease typically manifests itself with signs and symptoms similar to internal derangement. The disease is characterized by free-floating or attached cartilaginous bodies in the joint space. In this article, the authors present a case of synovial chondromatosis and discuss its pathological process. They also discuss diagnostic approaches and current treatment.

Alveolar bone loss one year following ovariectomy in sheep.

There is little information concerning the incidence of alveolar bone loss in estrogen-deficient women. Ovariectomized sheep are valid models for study of the effects of estrogen deficiency on bone metabolism. The objective of this study was to compare alveolar bone loss in control (C) and ovariectomized sheep (OVX) at 3 and 12 months following surgery. OVX animals had decreased serum levels of 17-beta-estradiol and increased serum levels of osteocalcin, IL-6, and urinary levels of deoxypyridinoline which, taken together, suggest development of osteoporosis. The mean probing depths and percentage of sites with pocket depths 4 to 6 mm and > 6 mm were significantly greater in OVX than C at each time period and in OVX were significantly greater at 12 months that at 3 months. Gingival tissue interleukin-6 (IL-6) levels (but not the number of IL-6(+) cells) were elevated adjacent to deep periodontal pockets; however, there was no significant elevation of levels of the proinflammatory cytokines IL-1 beta and IL-8 within gingiva. Taken together, the data suggest a systemic contribution for progression of periodontal disease associated with estrogen deficiency. This may involve upregulation of systemic IL-6 synthesis and transfer to gingiva in serum, resulting in enhanced IL-6 accumulation within the gingival tissues or reduced bone density allowing for a greater amount of alveolar bone loss.

The semiconstrained total shoulder arthroplasty.

In a two-year follow-up on sixteen total shoulder arthroplasties done with the semiconstrained Stanmore prosthesis, we found that patients with rheumatoid arthritis or osteoarthritis of the glenohumeral joint noted a greater relief of pain, were more satisfied with their surgery, used fewer analgesics, and had a greater increase in range of motion than patients with traumatic arthritis. Patients with irreparable rotator-cuff injury demonstrated the poorest range of motion postoperatively. Younger patients gained significantly more motion than older patients. All patients continued to have difficulty with lifting heavy loads. Complications consisted of one patient with a chronically dislocating prosthesis, one patient with a deep wound infection, and one with a postoperative wound dehiscence. The average follow-up was 31.4 months, ranging from twenty-four to fifty-three months.
