ABSTRACT
Total hip replacement (THR) is replacing the prosthesis stem similar to human bone that takes advantage of the material with both good mechanical properties and biocompatibility to the damaged articular surface. Thus it can not only alleviate or even eliminate the pain but also effectively maintain the joint stability and freedom and restore its normal performance. Finite element analysis was used in this study to establish a 3D model of artificial hip stem, and explore its fatigue properties of different materials to ensure the safety and reliability. The calculating obtained two results of different metal hip prosthesis, including lifetime and deformation. The minimum service life of titanium prosthesis reaches 568 million times, which satisfies ISO standards, while the stainless steel does not suit to be a prosthesis material.
