Abstract

One of the correction methods of children’s flat foot is calcaneal insertion. The purpose of this work is to determine the performance of calcaneal stop by using two bioco MPatible materials. The Finite Element Method (FEM) is used. The material analysis is AISI 316L steel and Ti-6Al-4V titanium alloy. Using Cuban anthropometric models, loads were calculated based on foot biomechanics and body weight of boys and girls aged 10 and 12. The results show that the implant model ensures the mechanical strength of the two materials. The difference between the two stresses is 4.44 MPa, accounting for 5% of the difference. Both materials have sufficient mechanical strength reserves because the maximum stress is less than the elastic limit of the material and ensures the mechanical strength of the calcaneal stop design.
