Usefulness of a new technique for hind limb immobilization in rats for the study of tendon healing.
To study wound repair in rat Achilles tendon, we utilized a novel surgical method for immobilizing only one hind limb. In this technique, the femoral vessels were preserved while the skin, muscles, nerves and the shaft for the femur were transected. The limb was then rotated and sutured to lie on the posterolateral flank of the animal. ⋯ In 2 weeks, the gap was completely occupied by fibrovascular tissue that was beginning to align along the long axis of the tendon. By the 4th week, remodeling had occurred and the site of the wound had almost blended with the rest of the tendon. We conclude that this new technique of hind limb immobilization causes little stress on the animal, and it can be useful for the study of tendon healing.

Synovectomy of the elbow was performed on 54 patients (70 elbows) with rheumatoid arthritis. The mean follow-up time was 7.5 years (range 1.5-22 years). Clinical evaluation showed marked relief of pain in 28 elbows (40%). ⋯ The mean carrying angle was 10 degrees in valgus. Measurement of strength in flexion and extension showed a reduction of approximately 50% compared to age-matched healthy controls. Reoperations were performed in 10 elbows (14%); the interval between the primary synovectomy and second operation in these cases averaged 8 years.

The value of intramedullary reaming in the treatment of chronic osteomyelitis of long bones.
Between 1985 and 1990 25 patients with chronic osteomyelitis (osteitis) of long bones were treated by intramedullary reaming. In most cases the aetiology of the osteomyelitis was posttraumatic. 22 of these patients who had undergone intramedullary reaming at least 6 months ago were evaluated. ⋯ One patient produced a little extraosseous sequestrum 3 months after the operation but since then has had no recurrence. The purpose of this study is to propose intramedullary reaming as an excellent treatment for chronic osteomyelitis of long bones and show the pathophysiological background that led to this modality.
