Chevron osteotomy for hallux valgus: Surgical indications and technique

The Chevron osteotomy of the distal first metatarsal is an effective procedure for the correction of mild to moderate hallux valgus deformities associated with an increased intermetatarsal angle. The surgical technique is described in detail with emphasis on achieving adequate correction of the deformity and avoiding complications. Postoperative care is important in maintaining the hallux correction and regaining metatarsophalangeal range of motion. With appropriate patient selection and careful technique, satisfaction with the Chevron procedure is high with most series reporting 80% to 90% satisfactory results. Recurrence of the deformity, decreased metatarsophalangeal range of motion, cutaneous neuromas, malunion, and avascular necrosis of the metatarsal head are potential complications.
