Angular Correction with Chevron-Akin Double Osteotomy in Mild, Moderate, and Severe Hallux Valgus:

摘要

Category:BunionIntroduction/Purpose:Hallux valgus affects a substantial number of patients requiring foot and ankle orthopaedic surgery. Chevron osteotomy is commonly used in mild hallux valgus for angular correction, and the chevron-Akin double osteotomy is a more powerful tool, with presumed usefulness in moderate and severe deformity. The objective of this study was to use radiographic analysis to determine the average and maximum corrections achievable with the chevron-Akin double osteotomy.Methods:This retrospective study included a total of 30 patients and a total of 33 feet. Pre- and postoperative hallux valgus angles (HVA) and intermetatarsal angles (IMA) were evaluated using standard weight-bearing AP plain x-rays and the differences pre- to post- were calculated. Patients were grouped based on the severity of preoperative hallux valgus into mild, moderate, and severe pathology. The pre- to post- changes of HVA and IMA, and the postoperative values of each angle, were compared between severity gr...
