Thirteen elbows in 11 patients with rheumatoid arthritis were treated with Kudo type, uncemented total elbow arthroplasties. Prior to surgery, the elbows were grade 4 or 5 according to Larsen radiological criteria. The patients were followed for an average of 4.3 years (range, two to nine years) .<BR>According to Kudo's category, there were 2 elbows with painful stiffness, 9 with painful instability, and 2 with ankylosis. The results, assessed according to the scoring system of the Japanese Orthopaedic Association, revealed remarkable improvement in pain, ROM in flexion and supination of the elbow, and function. Average rating of the elbows improved from 39 to 69 points. The mean flexion arc of the elbows improved from 101°to 130°, which is statistically significant. Although radiological findings revealed radiolucent lines around the ulnar component in 4 patients, total elbow arthroplasty is a valuable procedure to restore daily life activities of patients with rheumatoid arthritis.
