    • In the surgical operation of total hip replacement an acetabular prosthesis is inserted into an acetabulum in the human pelvis and a mating femoral component is inserted in the femur. One of the major problems after such an operation is the danger of dislocation of the hip as a result of particular movements of the subject.
      This invention provides an acetabular prosthesis (1) including an outer surface (2), a femoral head receiving surface (3) and a face (4) which joins the edges of the two surfaces (2, 3), the femoral head receiving surface (3) being a blind bore extending from the face (4) towards the outer surface (2) along an axis (8) which is at an angle to the normal (9) to the plane defined by at least a major portion of the edge of the outer surface (2).
    • 在全髋关节置换的外科手术中,将髋臼假体插入人体骨盆的髋臼中,并将匹配的股骨部件插入股骨中。 在这种手术之后的主要问题之一是由于受试者的特定运动导致髋关节脱位的危险。 本发明提供了一种髋臼假体(1),其包括外表面(2),股骨头接收表面(3)和连接两个表面(2,3)的边缘的表面(4),股骨头接收表面 (3)是沿着轴线(8)从所述面(4)朝向所述外表面(2)延伸的盲孔,所述轴线与所述法线(9)成角度地延伸到由所述面(4)的至少大部分 外表面(2)的边缘。
