CONGRESO Test bench development for femur stability assessment


This paper shows the design and development of a test bench for human femurs. The main uses of this test bench will run from artificial femurs comparison with real femurs, to join stability assessment after bone a fracture repair. Among this uses is specially designed for condylar fractures testing. The test bench is developed from a self-made existing tensile/compression testing machine. The design procedure is supported by a literature review about the bone mechanical behavior and composition generally and the knee joint performance and repair particularly. On the basis of this review, the machine was designed to simulate the adduction and abduction movements of the joint. The magnitudes to be measured are: the compression force, the bone displacement (vertical) and the knee joint rotation.
