Introduction: Hallux Valgus (HV) is a dynamic foot deformity. The biomechanical factors are not completely understood. Recently, a relation between medial foot arch collapse, with subsequent foot pronation and excessive pressure on the first metatarsophalangeal joint, and HV deformity has been investigated. Therefore, in this study we aim establish a relation between the severity of HV and flatfoot deformities. Methods: We retrospectively reviewed the preoperative upright foot radiographs of patients submitted to HV surgical correction and measured the Intermetatarsal (IM), HV, Meary’s and Medial Arch (MA) angles. Re-intervention cases were excluded. Results: 131 feet from 120 patients were evaluated. There was a moderate, positive correlation between IM and Lateral Meary’s angles and also between IM and MA angles. As expected, IM and HV angles were str.. Read More»
