• Total replacement of the elbow joint has been performed on 86 elbows at the Mayo Clinic, all but 15 in patients with rheumatoid arthritis. The Mayo design, which replaces both radiohumeral and humeroulnar joints, was used in 41 elbows, almost all in rheumatoid patients, with 71% good results. The Coonrad hinge with polyethylene bushings was used in 34 elbows; it was successful in 64% of rheumatoid patients, but failed in 46% of posttraumatic patients with bone loss. Previous designs have failed because of humeral loosening. Total elbow replacement is a technique still to be perfected in medical centers before general release.
