N2  - The number of hip operations performed by inserting implants has continuously increased in recent years. In Germany 110 673 femoral head fractures of female persons were diagnosed in the year 2004. To minimize the surgical intervention, the femoral head is saved whenever possible and fixated by screws or nails. Thereby, the induced stiffness change leads to an adaptation of the material with respect to the new loading situation. The very same adaptation can cause a repeated failure of the femoral head. The present work introduces a numerical model, which is able to anticipate the adaptation process so that it is possible to make a statement about the failure probability in advance. The model considers the anisotropy of the bone material as well as the influence of its microstructure. The model will be implemented into two different Finite Element codes. Finally, the capability of the model is demonstrated on some numerical examples.
