000200043 520__ $$aNowadays, pain and mobility issues of the hip such as arthritis bring more and more people to go through a hip replacement. The primary stability of an implant is essential for the long-term success of hip arthroplasty. Excessive micromotion is an indicator of a poor primary stability. The objective of this project is to develop a numerical model that allows to identify the micromotion at the bone-stem interface in a hip joint in compression. This would make it easier to anticipate the osseointegration of an implant after an operation. The geometries of the implant and the femur are extracted from CT-scans and used for a numerical model developed using Abaqus/CAE 6.13-3. The initial method applied doesn’t give any results and not a single iteration is achieved because of too large overclosures. Therefore, alternatives are proposed, mainly in order to improve the geometry of the model. Some of them bring improvements, while others don’t bring a change for the better, but none of them is really efficient and offers satisfactory results. The problem seems thus to be in the contact definition, which should be deeper investigated, in order to find a solution to make the simulation work.
