ANISOTROPIC MODEL OF CANCELLOUS BONE.
A model is proposed, based on experimental observations, which enables one to predict the transversely isotropic elastic constants of cancellous bone in the tibia from morphological measurements in the transverse plane. The basic assumptions of the model, besides transverse isotropy, are that: (i) deformation under vertical loading (along a direction parallel to the long axis of the tibia) is governed by axial compression with little or no buckling prior to failure, (ii) deformation under horizontal loading (along axes lying in the transverse plane) is not restricted to axial compression alone, but may include a substantial amount of bending or buckling of the trabeculae, (iii) the stiffness of the osseous tissue of cancellous bone is necessarily much lower than that reported for cortical bone.
