Abstract
The present invention essentially relates to a hip joint endoprosthesis stem for cement-free or cemented anchoring in bones that is anchored in the femural neck and in the proximal metaphysis and preserves the internal spongiosa and compact structures that reinforce the femur, that gives the design element axial access to the medullary canal, and possesses parabolically curved outer surfaces to optimize the transfer of force to the bone.
