Cup for a knee-joint prosthesis
摘要:
Metal socket (10) for a joint endoprosthesis, the outer surface (11) of which comprises at least three circumferentially extending surfaces (12, 13, 14) of spherical segments each having a different radius (R1, R2, R3). A metal socket for a joint endoprosthesis has an outer surface which includes at least three circumferentially extending, outwardly convex surface regions each having a different radius. The outwardly convex surface regions are exclusively surfaces of spherical segments, centers of which lie on a common axis of rotation, such that a radius of a medial spherical-segment surface is smaller than a radius of a polar spherical-segment surface, but larger than a radius of an equatorial spherical-segment surface.
