Abstract
Hip-joint endoprosthesis system with a plurality of, in particular leaflike, prosthesis shafts (1.1′, 1.2′) for anchoring in the femur, wherein each shaft expands substantially on all sides from a distal end ( ) towards proximal and comprises an anchoring section with a shaft long axis (A ) that merges medially with an arch (7.1′, 7.2′) that continues into a prosthesis neck (9.1′, 9.2′) with a prosthesis-neck axis (A ), such that the shafts differ with respect to a reference-point distance (A ′, A ′, A ′) between the shaft long axis and a reference point (R ′, R ′, R ′) on the prosthesis neck axis, which identifies the position of the center point of a joint ball set onto the prosthesis neck, and such that that the length (l) 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.
