Managing the stiff elbow: operative, nonoperative, and postoperative techniques.

Elbow contracture may be caused by intrinsic or extrinsic limitations or a combination of both. Evaluation of the specific structures guides the development of an effective therapy treatment program. Intrinsic contractures are by definition due to joint/intra-articular incongruency, and therefore therapy and splinting cannot provide increase in joint motion.

Antibiotic prophylaxis and infection resistance of massive tumor endoprostheses during chemotherapy.

Fifty-five consecutively treated patients with malignant bone tumors had preoperative and postoperative chemotherapy by one oncologist. These same patients had massive bone resection and cemented endoprosthetic bone replacement by one orthopaedic oncologist. Despite 143 instances of documented fever and/or neutropenia in 45 of these 55 patients, no known deep periprosthetic infections developed in any patient during follow-up (mean, 29.

Long-term durability of cemented primary total hip arthroplasty.

The results of all primary cemented total hip arthroplasties that were performed at UCLA Medical Center between 1974 and 1982 and had at least 1 year of follow-up evaluation were reviewed. Five hundred ninety-seven hips were implanted in 513 patients receiving a T28 (81%), a TR28 (16%), or a Charnley (3%) prosthesis (all from Zimmer, Warsaw, IN). The overall 15-year survival of the implants was 82%, although age at surgery was a strong predictor of implant failure (P < .

The effect of experimental hemarthrosis on joint stiffness and synovial histology in a rabbit model.

The effect of a single injection of unpreserved blood on joint stiffness and on synovial and cartilage histomorphology in the ankle joints of rabbits was determined at ten and 28 days after injection. The same volume of saline was placed in the contralateral ankle for comparison. After ten days, the hemarthrosis ankle was stiffer than the control ankle (p < 0.

Effects of antihistamines on joint stiffness and bone healing after periarticular fracture.

In an effort to blunt the inflammatory response following injury, we studied the effects of antihistamines on joint stiffness and bone healing after periarticular fracture. The hind limbs of 37 New Zealand white rabbits were instrumented with intramedullary Steinmann pins to allow immobilization after creating a distal tibia fracture. After periarticular ankle fracture, the rabbits were divided into groups to receive chlorpheniramine, low-dose terfenadine, high-dose terfenadine, or no antihistamine.
