A three dimensional two arch model of a normal foot for stress analysis

A three dimensional two arch model of the foot skeleton with cartilages and ligaments between bone segments is developed taking into account the predominant muscle forces. The model is used to study the regions of high stresses during mid-stance phase of walking for a normal foot. The stress analyses are carried out using finite element software package NISA. The results of there analyses could possibly help in understanding better the factors contributing to tarsal disintegration in leprosy.
