摘要

Hallux valgus (HV) was one of the most frequent human foot deformities. The aim of this study was to evaluate mechanical responses and stabilities of the plate implants and Kirschner wire (KW) after the distal metatarsal osteotomy in HV treatment by using finite element (FE) analysis. A three-dimensional FE model of lower extremity was developed to evaluate the four plate fixation methods and three KW fixation methods in weight bearing. The results showed that all the plate fixations revealed better first metatarsal stability than KW. For the result of the contact pressure, the 6-holes-6-screws dynamic compression plate implant had highest result than others plate implant. Adding the bandage to the KW fixation had a highest result in all implant.
