Abstract
BackgroundGood clinical and radiological outcomes in mild-moderate hallux valgus (HV) can be achieved with Chevron osteotomy (CO) and modified-Mitchell osteotomy (MMO). The main goal of the present study was to compare the clinical and radiological outcomes after CO and MMO in HV. MethodsThe study included 45 patients, comprising 40 females with a mean follow-up of 87.5 ± 27.8 months. The outcome measurements of metatarsal length (MT1), HV angle (HVA), intermetatarsal angle (IMA), clinical outcomes, and metatarsalgia were evaluated pre- and postoperatively. ResultsNo significant difference was determined between the MMO and CO groups in respect of metatarsalgia and AOFAS scores. The CO resulted in a significantly larger decrease in the MT1. The mean HVA and IMA correction was significantly greater after MMO than after CO. ConclusionSince MMO may prevent MT1 shortening, which is a typical problem in the Mitchell osteotomy, MMO may be preferred over CO in patients with preoperative shortened first metatarsal.
