A stainless-steel or titanium prosthetic replacement for the trochlea and capitellum was developed and used in ten elbows, five with post-traumatic lesions, three with rheumatoid arthritis, and two with ankylosis secondary to hemophilia. After follow-ups of from one to seven years, the results were found to be unpredictable or poor in the patients with inflammatory arthritis or hemophilia, while a stable, painless elbow with a functional range of motion was achieved in four of the five patients with post-traumatic lesions.
