Abstract
Muscular weakness may alter the mechanical stress flow in bones, thereby interrupting the homeostatic conditions for normal bone mass maintenance. In this study, we developed a biomechanical model of a typical planar trabecular lattice at the femoral neck for predicting long-term changes in trabecular thickness and mechanical properties at this site, under muscular weakness. A combination of hip joint loads lower than 20% the normal load and gluteus force outputs lower than 60% the normal force output resulted in osteoporotic bone structure in terms of morphology, strength and stiffness.
