ABSTRACT:
Endoprosthesis, in particular a hip joint prosthesis, provided with a hollow shaft being implantable in a hollow space of a bone, being of a tubular and curved shape and diminishing with respect to its diameter and material cross-cut, whereby, from the end that is near to the joint towards the end that is far away from the joint, the bending rigidity of the shaft diminishes to a relatively larger extent than the longitudinal rigidity of the shaft.
