Evaluación con distintos materiales de clavos endomedulares para fémur y tibia mediante elementos finitos

Abstract

In this work two types of intramedullary rod (IM), the first for tibia and the second for femur, are analyzed by using the finite element method, with two different materials. IM rods are used to align and stabilize fractures, and are inserted into the bone marrow canal, in the extremities bone center. One of the significant advantages of IM rods, over other fixation methods, is the rod-bone load share; thereby the patients quickly are able to use the injured extremity. However, for obtain the best device behavior, under static and dynamic forces, the finite element method are used. With this method aid, the tensional stress field and the safety factor are also achieved. Lastly, the numerical method results are validated by analytic results comparison. © Springer-Verlag Berlin Heidelberg 2007.
