Hip Muscles

Hip fractures are largely considered as a major health-care problem. Several patientspecific finite element models of the isolated femur are proposed to evaluate fracture risk. However, because of their role in femur stress distribution, soft tissue covering the hip should also be considered. Such modeling is particularly complex and major difficulties are related to volumic muscle mesh generation, to specific muscles constitutive equations and numerous contacts within the structure. A method was based on deformation of a parameterized muscle mesh was proposed to get rapidly a patient-specific non distorted mesh. Based in this mesh, finite element model included bones and soft tissues, with surface contact elements between components. Hyperelastic constitutive equations, with hypothesis of incompressibility and isotropy were used to model soft tissue mechanical behavior. Preliminary simulation with quasistatic lateral compression was performed to verify the coherence of the model’s response.

A New Technique

Abstract A finite element model of the tibio-femoral joint in the human knee was created using a new technique for developing accurate solid models of soft tissues (i.e. cartilage and menisci). The model was used to demonstrate that constraining rotational degrees of freedom other than flexion/extension when the joint is loaded in compression markedly affects the load distribution between the medial and lateral sides of the joint. The model also was used to validate the assumption that the bones can be treated as rigid.
