Abstract
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.
