ABSTRACT
The structure optimization of the human hip joint design has important scientific significance and clinical value in treatment of diseases of the joints, artificial joint replacement puter-aided manufacturing of the prosthesis. Basing on medical images of the human hip, reverse engineering, computer-aided design, and finite element methods were adopted to study the femur and femoral head design of custom artificial hip joint, Theoretical analysis was also conducted as well. In the end, through analysis parison, a good structure of the artificial hip was obtained.
In this study, high-precision medical instruments were used to get the human hip medical image data (including CT and MRI). Reverse engineering techniques was employed to reconstruct three-dimensional model of the hip, design artificial hip stems and the femoral head. Innovative design of various forms of microscopic morphology of the femoral head. After the building of three-dimensional model of hip replacement, finite element software was used to analyze the mechanical properties of simulated clinical surgery. The results of the study have great significance in the design and clinical applications of artificial hip prosthesis.
