Numerical simulations of the 3D virtual model of the human hip joint, using finite element method.

ABSTRACT

In this paper, we present a three-dimensional mathematical model for a normal hip joint. The three-dimensional finite element model has been constructed based on Computer Tomograph scans of the bones. The obtained 3D model is studied using the finite element method, taking into consideration the real structure of the bone and the mechanical characteristics of cortical and spongy. The FE model of hip joint, the material properties used to simulate the behavior of the cortical and trabecular bone (of femur and coxal bone) and the cartilage, as well as the boundary conditions are presented. The distribution map of the axial and global movements on the global model and the distribution map of the axial and von Misses strain in the cartilaginous surface of the femur are presented.
