Percutaneous Surgery for Mild to Moderate Hallux Valgus.
Patients who undergo percutaneous chevron-Akin osteotomies have less pain at follow-up, greater correction of hallux valgus angle, and a shorter operation time compared with open osteotomies. Stable fixation of the chevron osteotomy allows early full weight bearing and mobilization of the first metatarsophalangeal joint. This article describes the surgery technique, including reduction of the first metatarsal head after translation, accurate positioning of the proximal first metatarsal fixation screw, and removal of the dorsomedial prominence of the first metatarsal head.
