To fully understand and predict the mechanical behavior of bones, not only the mechanical characteristics but also the morphological characteristics should be investigated, because bone tissues are a porous composite material.
Materials and Methods The 12 th thoracic vertebrae were obtained from 85 years female and 48 years male cadavers and these were immediately kept in freezer at -25�.
For the material properties of vertebral trabecular bone in the FE models, the Young's modulus of 10� and the poisson's ratio of 0.3 [1] were utilized.
The material property for the FE analysis was considered to be isotropic and displacement boundary conditions were applied to the specimens to simulate a uniaxial compression test using ABAQUS6.4 (HKS INC., USA).
