3D Muscle detailed ankle-foot model for finite element analysis

3D musculoskeletal finite element analysis of the foot kinematics under muscle activation with and without ankle arthrodesis.

A finite element foot model for simulating muscle imbalances

Introduction To overcome the expense and limitations of cadaveric testing, we developed a finite element (FE) foot model. Previous foot models have included hyperelastic materials, plantar fascia, and extrinsic muscle forces [1]. We also included the plantar fat pad and both distal and proximal cartilage in our model. We validated the model by comparing plantar pressures and joint angles to lit...

Finite Element Analysis of Foot and Ankle Impact Injury: Risk Evaluation of Calcaneus and Talus Fracture.

INTRODUCTION Foot and ankle impact injury is common in geriatric trauma and often leads to fracture of rearfoot, including calcaneus and talus. The objective of this study was to assess the influence of foot impact on the risk of calcaneus and talus fracture via finite element analysis. METHODS A three-dimensional finite element model of foot and ankle was constructed based on magnetic resona...

Comparative Finite Element Analysis of Jaipur Foot and Polyurethane Foot

FEA is amongst best methods that help users to solve complex problems. There are fixed number of nodes in each element of the model that define the element boundaries to which boundary condition and loads can be applied. The geometry of the structure, the load applications, stress and displacement gradients can be approximated in a accurate manner, if the mesh is finer. The problem with the foo...

Muscle-driven finite element simulation of human foot movements.

This paper describes a finite element scheme for realistic muscle-driven simulation of human foot movements. The scheme is used to simulate human ankle plantar flexion. A three-dimensional anatomically detailed finite element model of human foot and lower leg is developed and the idea of generating natural foot movement based entirely on the contraction of the plantar flexor muscles is used. Th...
