Testing of Intramedullary Nails Using Physiological Loading


The increased interest in using intramedullary nails for fixation of long bone fractures has created a need for more in-depth laboratory testing of these devices. Until recently, most testing has addressed bending strength, bending rigidity, and torsional strength as separate properties. In actuality, bending and torsion are applied simultaneously to an implanted intramedullary nail. This study presents a technique for mimicking physiological loading incurred by a intramedullary nail during walking gait and the results of tests performed using this method.
