- Abstract
The purpose of the study was to establish a 3-D finite element (FE) model of the hip joint to examine stress and strain characteristics during standing. The cross-sectional images of a hip joint of a normal adult male subject were obtained through CT and a FE model including both pelvis and bilateral proximal femurs was constructed using Mimics. The FE model was assigned with four different material properties in order to describe non-uniform characteristics of bone materials. By applying body weight in ANSYS, the relationship of stress, strain and bone mineral density of 12 sampling points in the femur was examined. Stress concentration in the femoral neck was extremely high in the reconstructed pelvis under gravitational load. The relationship between the stress and strain, and the bone mineral density was examined by using least square curve fitting. The hip 3-D finite element model is a highly accurate method to simulate the bone structure and its non-uniform material properties, and has the merit of completeness of structural integrity and details of meshed divisions. The study lays the foundation for biomechanical analysis of the femur, and can be used for human motion analysis and rehabilitation research.
