Cadaveric bone models

Cadaveric models are used to investigate the mechanical behaviour of implants under physiological loading. A new hip implant is compared with a similar clinically-established design by implantation in either side of a femoral pair. Cyclic loading is generally applied and the relative motion measured between implant and bone, using an optical marker based system (Vicon). The strength and failure mode are also documented.
