No change in stiffness correlation between sideways fall FE models with isotropic and anisotropic material properties.
Up to 14% difference in principal compressive strain of internal elements in femoral neck, head, and greater trochanter.
Changes in nodal strain due to anisotropy were limited to internal nodes, with minimal effect observed in surface strains.
Degree of anisotropy of trabecular bone could be underestimated by the conventional MIL measurement technique.
