Abstract
The invention relates to a ball-and-socket implant (I), in particular an acetabular implant, preferably in the shape of a spherical cup shell, said implant having at least one region with a surface structure (). The at least one region extends between the equator and the pole of the spherical cup shell. The surface structure comprises a plurality of structural elements (), each of which is formed by a plurality of intersecting ridges () with opposite inclinations. The number of structural elements () on the equator () or on a circle of latitude near the equator is the same as on a circle of latitude near the pole. The ridges () have a curvature such that the inclination of the ridges with respect to the circles of latitude, and thus an angle between a tangent of the ridge curvature and a circle of latitude, continuously increases from the equator () to the pole ().
