Background Hallux valgus is a frequent condition of the forefoot, resulting in cosmetic deformity and pain. Chevron osteotomy (CO) is widely employed for the treatment of hallux valgus. Chevron-Akin double osteotomy (CAO) was previously described and superiority over an isolated Chevron procedure was assumed. The objective of this study was to compare the short-to-middle term outcomes of CO and CAO. Patients and methods This study included 72 patients with established diagnosis of mild-to-moderate hallux valgus, treated by either isolated CO or CAO. The CO group included 46 patients (mean 51.5 years) with a mean hallux valgus angle of 27A degrees, while the CAO group included 26 subjects (mean 53.1 years) and a mean hallux valgus angle of 32A degrees preoperatively. All patients were reviewed by physical examination, and standardized questionnaire, and pre- and postoperative standing X-rays were performed. Matched group analysis was carried out to analyze statistical differences of both techniques. Results The patients were assessed and group matched at a mean of 1.37 years for the CO group and 1.04 years for the CAO group, postoperatively. Mean improvement of HVA (hallux valgus angle) was 10.6A degrees in the CO group and the CAO group improved by 17.5A degrees. DMAA (distal metatarsal articular angle) improved in the CO group by 5.4A degrees and in the CAO by 13.7A degrees. Mean AOFAS score improved by 27.9 (CO) and 21.5 (CAO). Patient satisfaction was high in both groups, with a tendency towards higher values within the CAO group. Conclusions These findings indicate that Chevron-Akin double osteotomy is a save and practicable procedure for the treatment of mild-to-moderate hallux valgus. Superiority of combined Chevron-Akin procedure over an isolated Chevron osteotomy might be limited to distinct clinical settings, but should not be generally assumed.
