Aesthetic Treatment of Tillaux-Chaput fractures

Abstract

Category: Arthroscopy Introduction/Purpose: This study aim to investigate the clinical result of treating Tillaux-Chaput fractures using the all-inside ankle arthroscopy technique. Methods: We retrospectively evaluated 23 Tillaux-Chaput fractures patients who underwent all-inside ankle arthroscopy technique and were follow-up from May 2013 to June 2016. There were 15 males and 8 females, with the mean age of 30.4 years (range, 10-57 years). Right ankle was involved in 15 patients and left ankle in 8 patients. Eighteen patients had single Tillaux-Chaput fractures and 5 patients had combined proximal fibular fractures. While 20 cases were diagnosed by X-rays and 3 cases by CT. Ankle arthroscopy was used through the anterolateral and anteriormedal approaches for closed reduction and internal fixation using Herbert screw(s). The joints function was performed using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot scale score. Results: Operative incisions of 23 cases were primary healing without complications of nerve, vessel and tendon injuries. The period of follow-up was 19.6 months (range, 12-25 months) and the time of Fracture union was 23.3 weeks (range, 12-36 weeks). At the time of last follow-up, none of the patients had any restriction in the ankle function and range of motion, with the ankle pain and weight-bearing walking pain. AOFAS score was changed from preoperative 53.3 points to 92.1 points, with the excellent-good rate of 100%. Conclusion: All-arthroscopy teatment by the anterolateral and anteriormedal approaches is a precise and effective method for closed reduction and internal fixation of Tillaux-Chaput fractures and deserves clinical application.
