Outcome of Hallux Valgus Deformity Correction Using Mitchell Osteotomy with Screw fixation

Mitchell osteotomy is one of first metatarsal distal corrective osteotomies for hallux valgus deformity. The purpose of this study was to evaluate the outcome of Mitchellosteotomy. Eighteen patients underwent Mitchell corrective osteotomy using screw fixation for hallux valgus deformities from 2011 to 2015 were included. Clinical outcome was assessed using American Orthopedic Foot and Ankle Score, Hallux metatarsophalangeal-interphalangeal scale, (AOFAS Hallux), visual analogue score, and changes in hallux valgus and intermetatarsal angles based on standard weight-bearing radiographs, at least one year after surgery. About 95 % of patients were completely satisfied. Mean of AOFAS score was 86.7 at final follow-up. The mean of changes in intermetatarsal and hallux valgus angles were 5.6 ± 3.1 and 17.0 ± 5.2 respectively. Pain of the cases based on visual analogue score decreased from 5.8 ± 0.8 preoperatively to 1.3 ± 1.2 postoperatively. There were no deep infections, non::union:: or osteonecrosis of first metatarsal head. Mitchell corrective osteotomy with screw fixation could bea simple and effective procedure to correct hallux valgus deformity with high levels of patient satisfaction.
