    Abstract:
    PURPOSE: To review the subjective and functional results of basal thumb metacarpal osteotomy for the treatment of trapeziometacarpal osteoarthritis. METHODS: Between July 1993 and November 1998, 35 thumb osteotomies without internal fixation were performed on 33 patients in the Christchurch Hospital, New Zealand. Records of 28 thumbs (13 right and 15 left) of 26 patients (17 women and 9 men) were available for review. Patients were reviewed using strength testing and the Michigan Hand Outcomes Questionnaire. RESULTS: The mean age of the 26 patients was 54 years (range, 30-69 years). Of the 28 thumbs, 22 (21 patients) had good or excellent results, 2 fair, one poor. The remaining 3 thumbs (3 patients) required further revision and were classified as failures. The mean follow-up period of the 25 thumbs (24 patients) not requiring revision was 34 months (range, 12-73 months). Good thumb motion was present in all hands with no trapeziometacarpal instability seen. Compared with the normative data, the strengths of key pinch, pulp pinch, and tripod pinch of our patients were significantly lower (22-32% lower), but not the grip strength. Michigan Hand Outcomes Questionnaire scores increased 28 (range, 1-56) points after surgery, with significant improvement especially in pain (+44 points), activities of daily living (one-handed tasks, +41 points), and satisfaction (+35 points). CONCLUSION: Basal thumb metacarpal osteotomy is a straightforward, conservative procedure that should be considered for grades II and III trapeziometacarpal osteoarthritis.
