[Biomechanical analysis of the loosening of the femur prostheses (author's transl)].
A comparison of the stresses determined in an expoxy model of the human femur both with and without an intramedullary endoprosthetic replacement indicates how loosening of the implant could occur due to inappropriate mechanical loading of the bone. The stress pattern explains the manner in which the prosthesis stem is loaded and also indicates how hip-joint forces are transmitted from the prosthesis to the bone. The results obtained were verified by strain measurements on prostheses implanted within fresh human cadaver femora.
