A New Alternative Surgical Treatment of Hallux Valgus, in Moderate to Severe Cases of the Disease With a Two-and-a-Half-Year Follow-Up

The study aims to evaluate the treatment of moderate to severe forms of hallux valgus with the lowest invasiveness in soft tissues and especially with an alternative modified Chevron osteotomy of the first metatarsal. Additionally, it emphasizes the necessity of the modified McBride procedure (capsuloplasty and release of specific concrete soft tissue structures) and the importance of the soft tissue manipulation in the particular surgery intra-operatively, as well as postoperative medical and personal care and duration of rehabilitation. Patients with an average age 58 years (range 51-65), who underwent a Chevron type osteotomy with combination of soft tissues interventions laterally and medially of the first metatarsophalangeal joint, for symptoms they had of systematic hallux valgus without any other degenerative problems in metatarsophalangeal joint between 2017 to the beginning of 2018, were retrospectively reviewed with an average follow-up of 29 months (range 26-31).

A modified Austin/chevron osteotomy for treatment of hallux valgus and hallux rigidus

Abstract

The purpose of this brief paper is to present the preliminary results of a modified Austin/chevron osteotomy for treatment of hallux valgus and hallux rigidus. In this procedure, the dorsal arm of the osteotomy is performed orthogonal to the horizontal plane of the first metatarsal, the main advantage being that this allows much easier and more accurate multiplanar correction of first metatarsal deformities. From 2010 to 2013, 184 consecutive patients with symptomatic hallux valgus and 48 patients with hallux rigidus without severe metatarsophalangeal joint degeneration underwent such modified chevron osteotomy. Mean patient age was 54.9 (range 21–70) years, and mean follow-up duration was 41.7 (range 24–56) months. Ninety-three percent of patients were satisfied with the surgery. Mean American Orthopaedic Foot and Ankle Society (AOFAS) score improved from 56.6 preoperatively to 90.6 at last follow-up, and mean visual analog scale (VAS) pain score decreased from 5.7 preoperatively to 1.6 at final follow-up (p < 0.05). In patients treated for hallux valgus, mean hallux valgus angle decreased from 34.1° preoperatively to 6.2° at final follow-up, and mean intermetatarsal angle decreased from 18.5° preoperatively to 4.1° at final follow-up (p < 0.05). One patient developed postoperative transfer metatarsalgia, treated successfully with second-time percutaneous osteotomy of the minor metatarsals, whilst one patient had wound infection that resolved with systemic antibiotics.
