The development of an unconstrained elbow arthroplasty. A clinical review.
This paper describes the development, operative technique and results of an unconstrained total elbow arthroplasty. Forty-seven elbow replacements were carried out in 44 patients between 1974 and 1982. There was a high rate of loosening in the early condylar replacements. The results in patients with post-traumatic arthritis were poor. The later design employs an ulnar stem, with a humeral stem if the distal humeral bone stock is poor. When used in carefully selected patients with rheumatoid arthritis, pain is reduced significantly, stability and movement are preserved and function is improved.
