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). |
