Abstract
A femoral hip-joint prosthesis having a tapered stem for implantation by cement. The prosthesis has a collarless shoulder at a proximal end and a stem extending therefrom to a distal end in tapered fashion. A logarithmically extending curvature of anterior and posterior side faces of a first subsidiary section of the stem combine with straight converging lines of a second subsidiary section of the stem to uniformly distribute pressure in the prosthesis within the femoral hip bone.
