摘要：

Experimental stress analysis on composite epoxy models of the human femur has been employed to study the exact manner in which the proximal end of the bone is stressed in the physiological condition as well as after implantation of a hip prosthesis of the intramedullary anchored type. Apart from the light thrown on the mechanical function of cortical and cancellous bone in the proximal region of the femur, a description of the stresses along the prosthesis stem has been obtained. The results were verified by strain measurements on prosthesis implanted within fresh human cadaver femora that were loaded to simulate one-legged stance in which case particular attention was paid to the action of the abductor muscles on the trochanter major.
