Fifty rheumatodi patients (fifty hands) had Silastic joint implants in
144 metacarpophalangeal joints. Average follow-up time was 2.5 years
(maximum 3.5 and minimum 1.5). At clinical examination, gross power, range
of motion, lessening of ulnar deviation, relief of pain, and appearance
were determined. The results were correlated with preoperative indications.
Postoperatively, there was no significant gain in gross power. The range of
motion was somewhat increased and the lessening of ulnar deviation was
marked. Relief of pain was achieved. Complications included fracture of
four of the 144 implants, one infection, and six cases of tendon
adhesions.
