Abstract

BackgroundThree-dimensional distance and coverage mapping (DM and CM) generated through weightbearing CT (WBCT) can aid in understanding the complex articular relationship in hallux valgus (HV). Minimally invasive (MIS) hallux valgus correction has become popular in correcting this deformity. Prior biomechanical studies have demonstrated that alterations occur at the first metatarsophalangeal (MTP…
