Long-term results following digital flexor tenosynovectomy in rheumatoid arthritis.

Abstract

A retrospective review of flexor tenosynovectomy for rheumatoid flexor tenosynovitis in the palm and digit was performed. Fifteen patients (61 fingers) were reviewed for at least 1 year (average, 4 years) after surgery. An average of 2.2 cm improvement in active flexion (pulp to distal palmar crease) was observed. A significant difference in preoperative and postoperative results was found. Sixty-seven percent of digits were classified as having excellent or good results, 21% fair results, and 12% poor results. The clinical recurrence rate was 31% and the reoperation rate was 15%. Only minimal complications from the extended surgical approach were observed. Debulking the fibro-osseous canal by excising a slip of flexor digitorum superficialis was associated with a reduction in the recurrence and reoperation rates.
