The invention relates to an orthopaedic implant. The orthopaedic implant comprises an acetabular carrier (10) and an acetabular shell part (100). The carrier includes a convex outer surface (14) having a hemispherical surface, an introduction curved surface (40), a flat flange surface (44), an undulating curved surface (54), and a flat tapered surface (28). The relief surface extends inwardly with respect to the flat tapered surface and the flat flange surface extends outwardly with respect to the flat tapered surface. The housing component includes a concave inner surface (112) having a tapered surface (118) configured to engage the tapered surface of the carrier. An annular groove (124) is defined in the concave inner wall of the housing component and is configured to receive the flat flange surface. 本发明涉及一种整形外科植入物，该整形外科植入物包括髋臼承载件(10)和髋臼壳体部件(100)。该承载件包括具有半球形表面的凸形外表面(14)、引入曲面(40)、平坦凸缘表面(44)、起伏曲面(54)以及平坦渐缩表面(28)。起伏曲面相对于平坦渐缩表面向内延伸，并且平坦凸缘表面相对于平坦渐缩表面向外延伸。壳体部件包括具有渐缩表面(118)的凹形内表面(112)，该渐缩表面被构造成接合承载件的渐缩表面。环形沟槽(124)
