Abstract
An artificial hip joint socket for fastening to a pelvic bone includes a metallic outer cup for an artificial hipjoint socket forming a concavity for receiving a hip. This cavity terminates at an equatorial edge. Supporting flaps for fastening to said pelvic bone are provided at the equatorial edge of the metallic outer cup. These supporting flaps define holes drilled for bone screws to pass through and as openings for checking the clearance from the bone. The supporting flaps are provided with preset lines of grooves for enabling preferential bending of said flaps along said at least one of said preset lines of grooves to conform said supporting flaps and metallic outer cup to said pelvis. In the preferred embodiment, the preset lines of grooves run exclusively in the region of the supporting flaps undisturbed by defined holes in the flap. The preset lines of grooves are arranged on the outer surface of the flaps toward the pelvis. Round depressions are preferably provided at the intersections between said preset lines of grooves.
