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.

经股骨截肢者与以前的方法相比，骨整合植入物有许多有价值的好处。然而，40%的患者表现为种植体早期松动或基台破裂。这些问题与术后康复和日常生活活动中作用于固定系统的负荷有关。在本工程中，直接测量在桥台上施加的实际荷载时：
