[Analysis of stress on the proximal femur in various kinds of loading using the finite element method].
Loading of the limb in bending hip position causes a torque loading component in respect to the femoral axis. In this condition a characteristical increase of the mechanical tension of the femoral surface occurs. The tension was calculated for different kinds of loading and for the first time in different bending hip positions by means of Finite-Element-Method (FEM). The results show, that the torque loading component causes different torsional deformations. Even in physiological gait patterns different sizes of torsion and even changing of the direction of the torsion could be demonstrated.
