Abstract
Aim: 40 linked total elbow replacements were inserted into 35 patients over a 12-year period. The mean age was 67.3 (48–87) years and the mean follow up 50 (8–134) months. Each patient had undergone at least 1 operation prior to the index arthroplasty (1–10). 27 elbows were ßail and 13 unstable due to previous failed total elbow replacements in 23, gross bony erosion due to rheumatoid arthritis in 9, distal humeral non-union in 6 and Charcot joints due to syringomyelia in 2. Methods: A Coonrad Morrey sloppy hinge prosthesis was implanted in 25 elbows and a Snap þt Souter Strathclyde prosthesis in 15. The technique included preservation of the triceps mechanism and early mobilisation in most cases. Results: At review 38 elbows had no or mild pain, 2 moderate, and no patient with severe pain. All patients achieved a functional range of movement. There was no linkage failure of any implant. Complications included revision for aseptic loosening of one humeral and one ulnar component, debridement for infection in 1 and curettage and bone grafting of a cement granuloma in 1. One patient with a Charcot joint developed a non- union after failure of plating and grafting of a periprosthetic fracture at the tip of the humeral component. In addition 6 had delayed wound healing, 2 ulnar nerve symptoms and 2 triceps weakness. Conclusions: In conclusion, a linked elbow replacement can reliably provide stability, mobility and pain relief in a ßail or unstable joint allowing the hand to be positioned in space and therefore the function of the limb is dramatically improved. This method is especially appropriate in elderly frail patients.
