Total elbow joint arthroplasty in patients with rheumatoid arthritis.

As a result of better patient selection, implant design, and surgical technique, the long-term results of total elbow arthroplasty in patients with rheumatoid arthritis has improved significantly over the past 10 years. The semiconstrained hinge implant is used in the presence of severe bone and ligament destruction. The non-constrained surface replacement requires intact bone and ligamentous supports. Best results are obtained if surgery is undertaken before severe soft tissue contractures, muscle atrophy, and neurologic disability of the involved extremity develop.
