Humeral hemiarthroplasty of the elbow joint in young patients with rheumatoid arthritis: a report on 7 arthroplasties.

This article evaluates the early results of 7 humeral hemiarthroplasties of the elbow joint in 5 female rheumatoid patients using only the humeral component of the capitellocondylar prosthesis. The follow-up period was 25 to 109 months. All patients were 50 years old or younger; 3 patients were between 22 and 26 years. Because all patients were rather young, the intention was to perform a procedure that conserves a maximal amount of bone stock for future salvage procedures. One prosthesis had to be removed because of an infection unrelated to the primary procedure. The remaining bone stock provided a stable and pain-free excision arthroplasty. The other arthroplasties showed good pain relief; however, postoperative motion was not as reliable as described for total capitellocondylar prostheses.
