The elbow joint is a key joint for positioning of the hand. Four operations have to be considered for the rheumatoid elbow: removal of
rheumatoid nodules and bursectomy, resection of the radial head,
synovectomy, and
arthroplasty.
Synovectomy and
arthroplasty are carefully analyzed, both from the point of view of recent international literature as well as personal experience.
Synovectomy of the elbow is highly effective even when performed relatively late (stage 3 according to Larsen-Dahle-Eek) insofar as
pain relief and swelling are concerned. In long-term disease, deterioration as assessed by radiology can usually not be prevented, but clinical improvement may be the reason for the relatively rare indication for
arthroplasty. According to recent literature, the results of elbow
arthroplasty vary greatly. Fully constrained hinges should no longer be used, and no decision has been made so far on whether semiconstrained or nonconstrained surface replacement is preferred. We use the semiconstrained GSB
Mark II prosthesis, which has provided results in nearly 50 cases that rank among the best reported from the point of view of
pain relief, improvement of ROM, and low complication rate. Use of our so-called transtricipital approach to the elbow has proved particularly valuable, especially with regard to lack of extension and muscle strength.
