Changes in Foot Width in Minimally Invasive Bunionectomy

Background: Minimally invasive bunionectomy (MISB) has emerged as a popular approach to treat symptomatic hallux valgus deformity. Although previous studies focused on distal foot width changes postsurgery, this research introduces a novel midshaft measurement to evaluate proximal transverse midfoot width, aiming for a comprehensive understanding of foot changes post-MISB. Methods: A retrospective review of 44 HV patients from an institutional registry was conducted. Demographic data, surgical details, radiographs, and foot width measurements were collected. Changes in hallux valgus angle (HVA) and intermetatarsal angle (IMA) were also measured. Results: Intraclass correlation coefficients (ICCs) demonstrated good to excellent interobserver reliability (all ICCs > 0.70) for all measurements. MISB resulted in a consistent reduction in distal foot width (P
