The aim of synovectomy combined with the Sauvé-Kapandji (S-K) procedure for the treatment of a rheumatoid wrist is to obtain a stable painless wrist that retains sufficient mobility for function. However, loss of motion occurs postoperatively in most cases. In our study of 59 rheumatoid patients, the results of the transposition of distal strips of retinaculum into the radiocarpal and ulnocarpal joints for interposition arthroplasty to maintain wrist motion (interposition group), and transposition below the extensors to provide a gliding surface (SK group) were evaluated.

To determine whether the risk of infectious complications after total joint arthroplasty is increased in rheumatoid arthritis patients who are treated continuously with leflunomide, the incidences of infectious complications in 41 rheumatoid arthritis patients who received continuous leflunomide treatment (leflunomide group) and in 41 patients who did not receive leflunomide within 4 weeks of surgery (nonleflunomide group) were compared. The incidence (6.1%) of local infection after surgery in the leflunomide group (82 procedures) was slightly lower than that (6.

Background: Synovectomy has been advocated for early treatment of the rheumatoid elbow. It has not been determined whether arthroscopic or open synovectomy is better and whether a preoperative arc of flexion of >90 degrees is an important prognostic factor.

Methods: Arthroscopic or open synovectomy was performed in fifty-eight elbows in fifty-three patients with rheumatoid arthritis and radiographic changes in the joint of Larsen grade 2 or less.

The purpose of this study was to assess the long-term results (more than ten years) of two types of cemented ulnar component with type-5 Kudo total elbow arthroplasty in a consecutive series of 56 patients (60 elbows) with rheumatoid arthritis, and to compare the results in elbows above and below a Larsen grade IV. There was no radiolucency around the humeral component. Patients in whom a metal-backed ulnar component and a porous-coated stem were used had better clinical results and significantly less progression of radiolucent line formation around the ulnar component.

The effectiveness of rotator cuff repair by augmented subscapularis transposition via the Leeds-Keio artificial ligament was evaluated in patients with rheumatoid arthritis undergoing total shoulder arthroplasty. The minimum follow-up period was 2 years. Final clinical scores (Hospital for Special Surgery scoring system) and the incidence of radiolucency and upward migration of shoulder components in 20 shoulders with rotator cuff repair by augmented subscapularis transposition were superior to those of 19 shoulders with cuff repair by subscapularis transposition alone and similar to those of 22 shoulders with intact rotator cuffs.
