Abstract:
A hip-joint endoprosthesis system comprising a plurality of prosthesis shafts for anchoring in the femur, wherein each shaft expands substantially on all sides from a distal end towards a proximal end and wherein each shaft comprises:an anchoring section comprising a shaft long axis that merges medially with an arch and continues into a prosthesis neck; and a prosthesis neck axis, wherein the shafts differ with respect to a reference-point distance between the shaft long axis and a reference point on the prosthesis neck axis, which identifies the position of the center point of a joint ball set onto the prosthesis neck, wherein the length of the projection of the overall extent of the prosthesis shaft from the distal end of the anchoring section to the reference point or to the proximal end of the prosthesis neck is the same in all prosthesis shafts, and wherein in the prosthesis shafts with different reference-point distances, a prosthesis-neck angle between the shaft long axis and the prosthesis-neck axis is specified differently, depending on the reference-point distance.
