Chevron versus Mitchell osteotomy in hallux valgus surgery: a comparative study.

Good clinical results have been reported for chevron and Mitchell osteotomies in mild hallux valgus (HV). The primary aim of the present study was to compare first metatarsal shortening after chevron and Mitchell osteotomies in HV. The secondary outcome measures were the degree of valgus correction, metatarsalgia, and patient satisfaction. A total of 84 patients were included in the present study and were treated from 2005 to 2007; 42 patients were in each group. The outcome measurements-first metatarsal length, HV angle, 1-2 intermetatarsal angle, satisfaction, and metatarsalgia-were taken preoperatively and at follow-up. The Mitchell osteotomy resulted in a significantly larger decrease in the first metatarsal length. No significant difference in transfer metatarsalgia was found. Approximately 30% of patients were mildly or not satisfied after HV surgery. Mitchell osteotomy leads to a larger decrease in the first metatarsal length. Patients with metatarsalgia performed poorly, and no significant differences in metatarsalgia were found. Preventing postoperative metatarsalgia is important for a successful outcome after HV surgery.
