Strain measurement was performed on loaded fresh human cadaveric proximal femurs before and after total hip femoral component implantation. Changes in the femurs’ strain state associated with loading through stainless steel and titanium femoral components were recorded. The role of proximal femur remodeling in femoral component loosening is discussed along with the likely effect of femoral component elastic modulus on the remodeling process.
