3-D Finite Element Model (FEM) of Human Foot in Balanced Standing Condition

In this study, a detailed 3D FE model of the human foot-ankle structure is created from reconstructing CT images. The foot FE model consists of 19 separate bones, 114 ligaments, and the plantar fascia, embedded in a volume of encapsulated soft tissue. By defining appropriate boundary condition and loading and also considering the main bone interactions, balanced standing is simulated. In this study, plantar pressure distribution and bone structure stress is evaluated. To validate the FE results, the values of predicted plantar pressure distribution, contact area and center of pressure (COP) position are compared with the experimental data.
