Combined Distal Metatarsal and Akin Osteotomies for Concomitant Metatarsophalangeal and Interphalangeal Hallux Valgus: Clinical and Radiological Outcomes.

Abstract

Combined metatarsal and Akin-type proximal phalanx osteotomies represent a surgical solution for concomitant metatarso-phalangeal and inter-phalangeal hallux valgus. This retrospective observational study aimed to evaluate clinical and radiographic outcomes following combined distal linear metatarsal and Akin osteotomies. The study included 42 feet from 37 patients, with a mean follow-up of 27.1 (range 24-37) months. Mean surgical time was 16.54 ± 4.17 minutes. Pre- and postoperative clinical scores and radiological parameters were collected. Positive outcomes with a low recurrence and complications rates were reported. A statistically significant improvement in the Manchester-Oxford foot questionnaire, the EuroQol 5D-5L dimensions instrument, the visual analogue scale, the intermetatarsal angle, the hallux valgus angle, the distal metatarsal articular angle, and the interphalangeal angle correction was observed. Despite the results reported, further prospective studies are needed to identify the most suitable patients for this combined osteotomy approach.
