[Biomechanical analysis of the cup prosthesis at the femoral head (author's transl)].
Physical aspects of load distribution within the femoral head beneath the "Resurfacing-Prosthesis" are analyzed. The cup prosthesis eliminates stress from areas which--according to the bone structure--are weight bearing areas and induces shearing forces within the femoral neck. Tangential forces appear in addition to increasing marginal stress. These unphysiological loadings are amplified in case of varus position of the cup. Biomechanically for the cup prosthesis the term "resurfacing" is not justified.
