In the present study, a 3D finite element model of a single trabecula from the human femur head is developed with the aim of evaluating the dynamics of water diffusion through bone tissue and the subsequent swelling of the specimen due to water uptake. Numerical results in terms of dimensional changes of the trabecula are in good agreement with experimental observations reported in literature. The results show iso-concentration maps at different instants of time. Furthermore, we determined the spatial distribution of the effective diffusion coefficients of water along the length (L), width (W) and thickness (T) direction of the trabecula. The findings suggest that the model could provide valuable information for bone microstructure characterization.

Abstract

In the present study, a 3D finite element model of a single trabecula from the human femur head is developed with the aim of evaluating the dynamics of water diffusion through bone tissue and the subsequent swelling of the specimen due to water uptake. Numerical results in terms of dimensional changes of the trabecula are in good agreement with experimental observations reported in literature. The results show iso-concentration maps at different instants of time. Furthermore, we determined the spatial distribution of the effective diffusion coefficients of water along the length (L), width (W) and thickness (T) direction of the trabecula. The findings suggest that the model could provide valuable information for bone microstructure characterization.
