In this paper the influences of loading conditions, bone shape and bone density on risks of fracture in proximal femur are studied. First, a finite element model of standard femur is constructed based on mean values of bone shape parameters measured from 31 femur specimens. To evaluate effects of shape parameters and density on fracture some additional models with various shapes and density distribution were also constructed. The results showed that with an increase of an angle of inclination, the fracture risk decreased. Longer femur neck mad the fracture risk higher. When the cross sectional shape of basicervical region was circular, the fracture risk decreased. And the influences of apparent density of cortical and cancellous bone on fracture risk were not significant in this study.
