Abstract

Purpose: The authors intended to analyze the operative results of mild to moderate hallux valgus treated with distal chevron metatarsal osteotomy. Materials and Methods: Twenty six feet of twenty three patients were followed for more than 1 year after the distal chevron metatarsal osteotomy. Biplanar osteotomy with wedge resection was done when the distal metatarsal articular angle (DMAA) was increased. The mean age was 39 years, and the mean follow up period was 27 months. Clinically preoperative and postoperative AOFAS hallux MP-IP scale and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, the 1st intermetatarsal angle, DMAA and sesamoid position before and after the operation were analyzed. Results: Distal chevron osteotomy was done in 15 cases and biplanar osteotomy was done in 11 cases. Clinically AOFAS scale was increased from 65.3 points preoperatively to 92.2 points postoperatively. Two patients were not satisfied with the results. Radiologically hallux valgus angle was decreased from $21.9^{\circ}$ preoperatively to $8.5^{\circ}$ postoperatively. The first intermetatarsal angle was decreased from $11.8^{\circ}$ preoperatively to $6.7^{\circ}$ postoperatively. DMAA was decreased from $11.8^{\circ}$ preoperatively to $5.5^{\circ}$ postoperatively. There was one case of minor wound infection. Conclusion: Distal chevron metatarsal osteotomy appears to be safe and satisfactory procedure for mild to moderate hallux valgus.
