Transfemoral amputees fitted with an osseointegrated implant are experiencing numerous valuable benefits compare to their previous method conventional attachment. However, 40% of them present an early loosening of the implant or ruptures of the abutment. These problems are related to the load regime acting on the fixation system during post-operative rehabilitation and daily life activities. In this project, the direct measurement of the actual load applied on the abutment during: · the load bearing exercises is essential to refine the post- operative rehabilitation program. · every-day activities is crucial to improve the design and testing of the implants and abutments.
