Abstract (en)

[origin: WO9943274A1] The invention relates to an outer shell (1) of a hip joint endoprosthesis, consisting of an essentially hemispherical shell with an outer surface (1a) and an inner surface (1b) configured for receiving an inner shell. The outer surface (1a) at least across a partial section (1g) is defined by a generatrix which has a constant radius (R) and rotates about a symmetry axis (A) and whose origin (1e) is located on a circle (1h) which extends concentrically and perpendicular to the symmetry axis (A) of the outer shell (1) and is situated in the area of the equatorial plane (1d). The prolongation of said generatrix (R) passes through the symmetry axis (A).
