dc.abstract.enBackground Chevron osteotomy is one of the most common approaches to hallux valgus corrective surgery. This procedure is often combined with Akin osteotomy of the proximal phalanx of the hallux. There are no definitive guidelines specifying the indications for a given osteotomy technique nor data on postoperative loss of correction or the effect of the type of first-ray surgery on the development of adjacent-joint arthritis. The aim of this study was to assess radiographic treatment outcomes via chevron osteotomy with and without Akin osteotomy. Methods The study evaluated 117 patients treated in the period 2016–2019. Ninety-nine of those patients underwent distal chevron osteotomy alone, and 18 patients underwent a combined chevron–Akin double osteotomy. The analyzed radiograms had been obtained preoperatively, at 6 weeks after surgery, and after a long-term follow-up. The following parameters were assessed: the intermetatarsal angle (IMA), hallux valgus angle (HVA), interphalangeal angle (IPA), postoperative recurrence of valgus deformity, adjacent-joint arthritis, and complications. Results Chevron-Akin osteotomy helped maintain lower HVA and IPA values in long-term follow-up in comparison with those in the patients who underwent chevron osteotomy alone. The chevron osteotomy group showed a significant increase in the mean HVA from 18.37° at the first follow-up visit to 20.81° at the last follow-up visit. There were no differences between the groups in terms of the remaining assessed radiographic parameters. Hallux valgus surgery does not increase adjacent-joint arthritis. Conclusion The use of combined chevron-Akin osteotomy does not affect HVA or IMA correction. The combination of chevron and Akin osteotomies reduces the risk of increased HVA and IPA in long-term follow-up. The additional Akin osteotomy does not increase the risk of adjacent-joint arthritis. Combining chevron osteotomy with Akin osteotomy is recommended in hallux valgus deformity correction.
