The comprehensive biomechanical analysis of microcosmic trabecular structure of cancellous bone

Femoral cancellous bone has microcosmic trabecular structure and its element characteristics effect the gross mechanical property of femur.Finding proper cell configuration and its distribution will be of great importance for the effective biomechanical analysis of cancellous bone.A lot of microcosmic trabecular models with several structures were used to study the biomechanical performance of the elements.The biomechanical analysis of the femur model with different trabecular structures and distributions were carried out with the combination of the Finite Element Method.The relation between the trabecular structure and its biomechanical characteristics is obtained.Based on analysis,better microcosmic trabecular structure and its distribution were found and which is utilized in building an analytic model of the femoral cancellous bone.The trabecular structure of cancellous bone can improve the gross biomechanical properties of the whole body.The optimized microcosmic element structure can be applied to the manufacture of the biological materials effectively.
