Abstract :
The artificial prosthesises currently used are only different in the femoral head size, neck length and stem thickness, but there is not any individualized prosthesis. At present, prosthesis looseness is the main problem of artificial femoral replacement, and individual matching level of joints is the bottleneck of restricting prosthesis replacement surgery. If we can design and produce corresponding individual artificial joints according to the patient´s bone shape and bio-mechanical characteristics, there will be a significant impact on human health and medical treatment. In this paper, I complete the reconstruction process of the CT three-dimensional finite element model of femur, with the help of powerful image processing functions of medical imaging system MIMICS. I load force with the experimental data provided by the VIMS laboratory, analyze the biomechanical properties of femur and investigate the influence of anteversion angle parameter on mechanical properties by FEM, The results indicated that the stress pattern of femur implanted was similar to the one of intact femur.
