Abstract:
ob<x>jective Compare the outcomes of the minimally invasive chevron and akin osteotomies (MICA) with open Chevron osteotomy for mild-moderate hallux valgus. Methods Data of 46 patients (52 feet) with mild-moderate hallux valgus from Jul 2017 to Feb 2020 were analyzed retrospectively. According to the results of preoperative doctor-patient communication, 24 patients were treated with MICA, while other 28 patients received open Chevron osteotomy. Perioperative data, radiographic parameters, and clinical outcomes were compared between the two groups. Results All patients were followed for more than two years. Bone healing and operation time in MICA group were superior to that in open group ( P<0.05). The complication rate in the MICA group (20.83%) was lower than that in the open group (32.14%) . The two treatment groups showed no differences in perioperative data, radiographic parameters, and clinical outcomes preoperatively (P>0.05). All clinical and radiographic outcomes improved significantly at post and follow-up evaluations in both groups (P< 0.001) with no difference between the groups (P>0.05). Conclusion The MICA and open chevron osteotomy showed an excellent efficacy for mild-moderate hallux valgus, with no obvious difference in effect
