Abstract: A wooden femur model was used together with matched cementless experimental implants to investigate the influence of some design concepts on the stress distributions within the proximal femur model, with emphasis on the longitudinal stresses on the outer bone surface, because the longitudinal stresses are believed to be the most important stresses in view of the laws of bone remodelling. In addition to the integration of alternative geometrical design concepts in a hip prosthesis design, the effect of using alternative materials upon bone stresses was also investigated. Stress evaluation was made by a combination of two-dimensional finite element analysis and strain-gauge measurements. The results and conclusions drawn from these experiments have led to a prototype of a so-called ldquophysiologicalrdquo hip prosthesis, in which are integrated a properly oriented collar, a hinge between stem and neck part, and a flexible stem.
