Hip prostheses computational modeling: Mechanical behavior of a femoral stem associated with different constraint materials and configurations

Abstract

Fatigue behavior of hip prostheses is usually assessed experimentally, through the implementation of mechanical tests according to International Technical Standards. Based on FE elastic-linear simulations, this study aims at investigating the stress resulting from loading conditions which are slightly different from the reference condition indicated in the ISO7206-4:2010 but which are reasonable from both a clinical and biomechanical point of view. Main results are reported and suggestions delivered for the assessment of risky conditions.
