Abstract

Isolated scaphotrapeziotrapezoid osteoarthritis is rare but can cause weakness and wrist pain. We present the results of a pilot study of interposition arthoplasty with a scaphoid trapezium pyrocarbon implant (STPI) by an open and arthroscopic approach for this problem. We performed this procedure in 10 hands in eight patients, all women, with a mean age of 60.5 (range 51–70) years. The average follow-up was 19 (range 2–24) months. Pre-operative X-rays in all cases identified an isolated degenerative arthritis of the scaphotrapeziotrapezoid joint. Average DASH evaluation pre-operatively of 49 was reduced to 39. All of the patients had functional improvement and returned to daily activities after 3 months. The results of this pilot study suggest that the STPI may prove a useful compromise treatment for this problem.
