Fig. 3.

cQCT-based FE models of the L1 vertebral body (A and C) and the proximal femur (B and D) of a control (A and B) and a subject (C and D). Distributions of elastic moduli of elements are indicated by different colors. Gray elements indicate poly(methyl methacrylate) layers. A portion of the vertebral body and half of the proximal femur have been removed for illustration purposes. E and F, Bone stiffness estimated from voxel-based FE models at L1 and at the femoral neck in controls (white columns), IOP (dark gray columns), and ILBMD (light gray columns) subjects. Comparisons vs. controls: **, P < 0.01.
