Biomechanics analysis of human proximal femur under four different standing postures based on finite element method

This paper proposed an effective finite element modeling method for human bone, which was suitable for orthopedic biomechanics research. Proximal femur models under four different standing postures were established and the stress distribution as well as the relationship between von Mises stress and adduction angle were analyzed. It was found that tensile stress would appear around the lateral femoral neck and the von Mises stress was the minimum when the adduction angle was around 11°. This paper was expected to provide some directions for clinical treatment of femoral fracture.
