Purpose: The purpose of this study was to the evaluate the clinical and radiographic results and complication of the Scarf osteotomy which is one of the surgical treatment of Hallux valgus. Material and Method: Fifty feet (30 patients) of moderate to severe hallux valgus deformity were operated by Scarf osteotomy procedure from January 2002 to July 2002. Patients were asked about their satisfaction in terms of pain, appearance and motion. The AOFAS clinical ratio scales and radiographic results for hallux valgus were evaluated. Result: The mean Hallux valgus angle improved from an average of 30.6 degrees to 9.0 degrees and the first intermetatarsal angle improved from an average 13.3 degrees to 5.2 degrees respectively. The preoperative mean AOFAS score was 58 points and on last follow up AOFAS score improved to 88 points. Complication which including troughing, nonunion, malunion was not developed. Conclusion: We found that Scarf osteotomy is a reliable operation for mild to moderate Hallux valgus deformity as regards firm fixation and early postoperative ambulation and large contact area for union.
