Abstract

INTRODUCTION:

Semiconstrained total elbow replacement is now a well recognised and reliable surgical option for advanced elbow disease, mainly rheumatoid arthritis.

METHODS:

We report a retrospective analysis of 31 primary total elbow replacements in 28 patients with a mean follow-up duration of 55 months. The mean age of the patients was 65 years. The indications included 27 cases of rheumatoid arthritis, 3 fractures and 1 case of osteoarthritis. Twenty-one elbows in nineteen patients were assessed using the Mayo elbow performance score (MEPS) in a special follow-up clinic. In the other nine patients (ten elbows), the assessment was carried out with case notes and x-rays.

RESULTS:

The mean pre-operative MEPS in the 21 elbows recalled was 40. This improved to 89 post-operatively (range: 55-100). Sixteen of the twenty-one elbows were considered excellent, two good, two fair and one poor. The range of movement was recorded in eight of the other ten elbows and the mean was 98°. At the last follow-up visit, x-rays were normal in 23 elbows although the ulnar component was loose in 3, the humeral component loose in 2. There were also two cases of non-union of the medial epicondyle and one patient had mild heterotopic ossification. Complications included one infection, which needed irrigation and debridement with a satisfactory final result, and two cases of ulnar nerve palsy/neurapraxia. Two elbows were considered failures due to severe pain caused by prosthetic loosening. These were referred for revision surgery.

CONCLUSIONS:

Excellent pain relief and good function can be achieved in the medium and long term with the Coonrad-Morrey-semiconstrained total elbow replacement prosthesis in patients with severe destructive elbow arthropathy.
