Figure 3. Relationships between density and orientation of the trabecular structure and the magnitudes of the various moduli and their principal mechanical directions. (A) Relation between bone volume fraction (BV/TV) and Youngs (E1,2,3) and shear moduli (G12,23,31) relative to the 3 principal mechanical directions. (B) Relation between principal structural direction (angles
MIL and
MIL) and principal mechanical direction (angles
E and
E). For each graph, n = 44.
