Methods: Forty-one patients (58 feet) with mild to moderate hallux valgus were treated by either percutaneous technique (n = 24) patients (33 feet) or by distal chevron osteotomy (n = 17) (25 feet). Results: In the percutaneous group, after a mean follow up of 49.36 months, the mean correction of hallux valgus angle (HV) was 26.69°in the intermetatarsal angle, average correction was 9.45°. The mean improvement of American Orthopedic Foot and Ankle Score (AOFAS) was 46.45 points. In the chevron osteotomy group, the mean follow up of 51.56 months, the mean correction of hallux valgus angle was 26.78°in the intermetatarsal angle, average correction was 9°. The mean improvement of AOFAS was 44.76 points. Conclusion: Both techniques gave satisfactory results. However, the percutaneous technique is safer than the distal chevron osteotomy.展开更多
