Abstract
Abstract The external bowl of the hip joint endoprosthesis is provided with a plurality of circumferential rows of projections. In addition, each projection is provided with a flank in a plane perpendicular to the axis of symmetry of the bowl and a second flank which faces the equatorial plane of the bowl which defines an angle of from 15 DEG to 45 DEG with the other flank. Upon penetration into bone tissue, the flanks displace and condense the tissue to approximately the same extent so that the axial force components acting on the flanks are approximately equal. This reduces the tendency of the endoprosthesis to be expelled from the bone.
