Abstract
A preliminary iterative 3D meso-scale structural model of the femur was developed, in which bar and shell elements were used to represent trabecular and cortical bone respectively. The crosssectional
areas of the bar elements and the thickness values of the shell elements were adjusted
over successive iterations of the model based on a target strain stimulus, resulting in an optimised construct. The predicted trabecular architecture, and cortical thickness distribution showed good agreement with clinical observations, based on the application of a single leg stance load case
during gait. The benefit of using a meso-scale structural approach in comparison to micro or
macro-scale continuum approaches to predictive bone modelling was achievement of the
symbiotic goals of computational efficiency and structural description of the femur.
