[Biomechanical considerations on stress and strain of the anchorage of femoral prostheses stems (author's transl)].
The nature of load and stress on implanted femoral prostheses is shown by simplified models. Bending stress is responsible for loosening and fracture of prosthesis stems. Implantation in valgus position diminishes the possibility of failure. Investigations on materials and the strength of form could clear up different influences and shall lead to allbountiful criterions and test-methods.
