Abstract
Stiffness predictions from finite element (FEM) models are compared to measured values for three bovine vertebral bodies in compression. Young´s modulus for trabecular bone was calculated using the measured apparent density and strain rate. Using this modulus, FEM models predicted a stiffness higher than the experimental values. The FEM models have a strong dependence on cortical thickness, yet a precise measurement of thickness was not possible
