Abstract
A metal fixation element is disclosed for receiving a plastic socket component of an artificial hip joint. The fixation element includes a frontal region which faces the pelvic bone. The frontal region has a central bore, with a screw thread to receive an insertion tool. The element also includes at least one conically tapering wall spaced from the frontal region. A self-tapping screw thread on the outer surface of the tapering wall provides for cementless fixation of the element in the pelvic bone. There is further provided an additional conically tapering wall between the frontal region and the first conically tapering wall. Three apertures are located in the frontal region. A cover element is rotatably mounted within the fixation element closely abutting the frontal region. The cover element has three equally spaced openings separated by continuous positions for selective opening and closing of the three apertures in the frontal region.
