Femoral Strength based on lesion location. Legend: Spherical lesions (A) in the proximal femur were created using Boolean subtraction of the spherical lesion from the intact femur. Lesion size was scaled to the minor width of the bone (W) and had a width of 70% of the minor bone width. Eight lesions were individually placed (B) at each axial level. Lesions for the neck, intertrochanteric, subtrochanteric, and diaphyseal axial positions were included (C). Voxel based finite element models were created from the solid models with material assignment based on mineral equivalent density (D). A head and greater trochanter load was applied to represent stair ascent loading
