무지 수근중수 관절염에 대한 대다각골 부분절제술 및 봉합사 단추를 이용한 현가술

Abstract

Purpose: Our goal was to investigate the clinical results of partial trapeziectomy and suspensionplasty with suture button for the thumb basal joint osteoarthritis. Methods: A prospective study was performed for patients who have been undergone partial trapeziectomy and suspensionplasty by a suture button fixation for Eaton stage II or III osteoarthritis. Clinical outcome measures included visual analogue scale (VAS) for pain, Quick disabilities of the arm, shoulder, and hand (DASH), pinch and grip power, and thumb movement. Radiographic measurements and complication were recorded. A p-value <0.05 was considered statistically significant. Results: Total number of the patients was nine, which included 8 females and 1 male. Average age at the time of surgery was 61.2±5.1 years old, and average duration of the follow-up period was 19 months (6-46 months). This procedure was carried out for dominant hand in 6 cases and non-dominant hand in 3 cases. In the early clinical outcomes at the postoperative 10 weeks, VAS measurement demonstrated statistically significant difference. Other clinical parameters; however, did not show as statistical significance at the postoperative 10 weeks. In addition, there was statistical significance in VAS, Quick DASH, grip and thumb range of motion, except pinch power at the last follow-up day. Serial radiographic change was shown during total follow-up period. Conclusion: Partial trapeziectomy and suspensionplasty using suture button revealed improved clinical outcomes and return to early daily activity by permitting early thumb motion. So this surgical procedure can be a good option for thumb basal joint osteoarthritis.
