Abstract

Purpose: The purpose of the present study is to evaluate the proximal metatarsal chevron osteotomy outcomes for moderate to severe hallux valgus more than seven year follow up. Materials and Methods: Between 1996 and 1998, hallux valgus 61 cases were evaluated. The follow up period was more than seven years. The clinical review analyzed by the hallux metatarsophalangeal-interphalangeal scale of the American Orthopedic Foot and Ankle Society, radiologic review by the hallux valgus angle, first and second intermetatarsal angle. Complication also evaluated. Results: Clinically, preoperative AOFAS score was average 43 points (range; $16{\sim}60$ points) which significantly improved to 88 points (range; $61{\sim}100$ points) at last follow up periods. Radiologically, the mean preoperative, postoperative, last follow up hallux valgus angle was $34^{\circ}$, $5.2^{\circ}$, $10.9^{\circ}$. The mean preoperative, postoperative, last follow up intermetatarsal angle was $15.3^{\circ}$, $3.3^{\circ}$, $5.3^{\circ}$. Postoperative angle change were no statistical significance (p>0.05). Complication were hallux varus 6 cases, metatarsophalangeal joint arthritis 2 cases, recurrence 1 case. Conclusion: Proximal metatarsal chevron osteotomy shows satisfactory outcome for moderate to severe hallux valgus more than seven year follow up.
