    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.

    摘要： An acetabular prosthesis has a shell component that is implantable within bone and a liner component that is matable to the shell. The shell has a generally convex bone engaging outer surface and a generally concave inner surface. A groove is formed in the inner surface of the shell and extends about at least a portion of the inner circumference of the shell. The liner has an inner concave surface and an outer, convex surface with a shape complementary to and matable within the inner surface of the shell. One or more deformable positive surface features is formed on the outer surface of the liner, adapted for selective mating with the slot of the shell. The liner may be joined to the shell by press fitting the two components together such that the positive surface features engage the groove.

    摘要： An acetabular shell is implanted at an acetabulum in a deficient pelvis to establish an effective acetabular site with increased support in posterior and superior directions for an acetabular bearing insert to be affixed in place in the acetabular shell for the reception of a femoral head of a femoral component of a prosthetic hip implant, the acetabular shell including a domed portion having a convex outer surface for engaging the acetabulum, a concave inner surface for reception of the bearing insert, the inner surface extending along a spherical contour up to a generally hemispherical extent, and a rim between the outer and inner surfaces, the rim being placed adjacent an equatorial location along the domed portion and including a superior segment, an inferior segment longitudinally opposite the superior segment, a posterior segment and an anterior segment laterally opposite the posterior segment, an anchoring plate integral with the domed portion adjacent the superior segment of the rim, and a supplemental support web extending along the rim from the posterior segment to the plate at the superior segment, the support web projecting beyond the equatorial location for providing supplemental support for the bearing insert in the posterior and superior directions.
