Quantification of the roles of trabecular microarchitecture and trabecular type in determining the elastic modulus of human trabecular bone

The roles of microarchitecture and types of trabeculae in determining elastic modulus of trabecular bone have been studied in mu CT images of 29 trabecular bone samples by comparing their Young's moduli calculated by finite element analysis (FEA) with different trabecular type-specific reconstructions. The results suggest that trabecular plates play an essential role in determining elastic properties of trabecular bone.
