Abstract :
The apparent correlation between bone density and susceptibility to fracture was evaluated using finite element modeling. Based on computed tomography data of an actual femur bone, a versatile virtual model was created and modified in order to simulate different bone geometries and densities. Under typical load conditions the highest strains were calculated for the inferior side of the femur shaft, and the anterior side of the femur neck close to the trochanter. Strain values consistently decreased with raising cortical bone content.
