Radiographic Measurements Associated with the Natural Progression of the Hallux Valgus Deformity during at Least Two Years of Follow-up:

摘要

Category:BunionIntroduction/Purpose:There have been few longitudinal studies regarding hallux valgus deformity. This retrospective study aimed to investigate the radiographic measurements associated with the progression of hallux valgus deformity during at least two years of follow-up.Methods:Seventy adult patients (mean age, 58.0 years; standard deviation [SD], 12.3 years; 13 males and 57 females) with hallux valgus who were followed-up for at least two years and underwent weight-bearing foot radiography were included. Radiographic measurements included the hallux valgus angle (HVA), hallux interphalangeal angle, intermetatarsal angle (IMA), metatarsus adductus angle, distal metatarsal articular angle (DMAA), tibial sesamoid position, anteroposterior (AP) talo-first metatarsal angle, and lateral talo-first metatarsal angle. Progression of hallux valgus deformity was defined as an increase of 5 degrees or more in the HVA during follow-up. Patients were divided into progressive and non-progressive groups. ...
