    • The invention relates to a hip joint socket, comprising an outer shell (1), with central axis (7), for fixing in the pelvic bone; a plastic intermediate shell (1a), with a hollow spherical inner surface and which can be detachably mounted in said outer shell, by means of an interlocking fit; and a wear-resistant inner shell (3), with a spherical outer surface (4), a central axis (8) and which is for housing a ball-joint of a femur shaft. The outer surface (4) of the inner shell (3) is mounted on the inner surface (2) of the intermediate shell (1a), by means of a fixed interlocking fit, in such a way that both central axes (7, 8) are congruent. The inner and intermediate shells (3, 1a) comprise interlocking means of a prismatic projection (5), at the vertex (9), on the outer surface (4) of the inner shell (3) and a prismatic recess (6), at the vertex (10), on the inner surface (2) of the intermediate shell (1a). Said interlocking means secure the fixed inner and intermediate shells (3, 1a) against rotation about their central axes (7, 8) and against tipping relative to each other. The projection (5) and recess (6) are arranged essentially congruent to and symmetrically about the central axes (7, 8). The hip joint socket is further characterised in that it has a minimal height, which ensures an optimal distribution of pressures.

    • The invention relates to an orthopedic bone implant (10) comprising an outer shell surface (12) which is in the form of a rotational body whose diameter widens in an axial direction. The invention also comprises a threading die (14) which is shaped on said shell surface (12). In addition, the threading die (14) has a constant ascending slope. The outer diameter of the threading die (14) correspondingly widens relative to the shape of the shell surface (12) in a spiral-like manner and in an axial direction. The thread path is divided into cutting teeth by recesses (16). The cutting teeth each have a profile back which is relief-ground with regard to the forward cutting surface of the cutting teeth, said cutting surface being arranged in a direction of rotation. The threaded profile of the threading die (14) decreases in width from the profile back (22) toward the profile base.
