Abstract
A femoral portion of a hip joint prosthesis comprises a shank portion which merges into an angled neck portion optionally via a collar, with the neck portion being connected or adapted to be connected to a joint ball. The upper or proximal portion of the shank is defined by a framework structure such that the distribution of the tension and thrust forces approximates the force distribution in the natural bone.
