Abstract:
PURPOSE: To investigate the clinical usefulness of hematoma distraction arthroplasty to treat advanced trapeoziometacarpal osteoarthritis of the thumb. MATERIALS AND METHODS: We studied 12 cases (1 male, 11 females) with osteoarthritis of the thumb that was managed with hematoma distraction arthroplasty using K-wire fixation. Of the 12 cases, 7 were Littler-Eaton stage III and 5 were Littler-Eaton stage IV. We investigated operation time, preoperative and postoperative visual analogue scale (VAS) score, preoperative and postoperative range of motion, grip power and radiologic changes. RESULTS: The mean patient age was 53.2 (39-61) years and the mean duration of follow-up was 19.5 (14-27) months. The average operation time was 52 minutes. The mean VAS scores at 6 and 12 months after the operation were 1.3 and 0.7, respectively. The range of motion and grip power of the finger improved postoperatively (15% in abduction, 18% in adduction, 25% in flexion, 14% in extension, 66% in grip power of the finger). On a simple 12-month postoperative radiologic exam, the interval between the scaphoid and first metacarpal bone had decreased 6.5 mm compared with the preoperative interval. CONCLUSION: The surgical treatment using hematoma distraction arthroplasty for trapeziometacarpal osteoarthritis is an effective method for pain relief, improvement of motion range and finger-grip power.
