In the article a detailed comparison of techniques used to develop detailed FE models of trabecular bone microstructure is presented. The FE models are built using a stack of microtomographic images of trabecular bone of 35μm3 spatial resolution. Compression test of a cylindrical sample taken from human proximal femur is virtually performed using FE models developed using different procedures. Effect of improper segmentation (deficiency/excess of bone volume), mesh smoothing, mesh density, use of hexahedral/tetrahedral elements, linear/quadratic shape functions is evaluated in a parametric study. Material model used in the study is based on results from nanoindentation. Obtained elastic properties of the sample are compared to experimental results from compression test.
