    摘要： Off-center liners can be used with an acetabular cup in hip replacement or revision surgical procedures. The liners (of metal or plastic) can be laterally spaced from the acetabular cup, angled relative to the acetabular cup and/or have an opening that is offset relative to the axis of the acetabular cup. The liners have an orientation indicator that identifies where the liner should be impacted (e.g., impaction location or point) by the impactor to ensure the liner is impacted in a square manner relative to the acetabular cup.

    摘要： Devices, apparatus, and systems for replacing at least some of the functionality of the natural hip joint and associated methods of implantation are disclosed. In one aspect a prosthetic acetabular cup system is provided. The system includes a metal shell comprising an outer surface for securely engaging a prepared portion of an acetabulum, an opposing inner surface, and at least one snap-fit engagement feature associated with the inner surface. The metal shell has a thickness less than about 1.0 mm between the outer surface and the inner surface. The system also includes a pliable articulating component having an outer surface including at least one snap-fit engagement feature sized and shaped to snap-fittingly engage the at least one snap-fit engagement feature of the metal shell. The pliable articulating component also includes an inner surface for articulatingly receiving a femoral head. The second component has a thickness less than about 3.0 mm.

    摘要： The invention relates to an artificial hip joint, in which the surfaces of both the socket and the ball of the joint are in the form of rotational bodies (rotational surfaces) deviating from the normal spherical shape. The rotational surfaces are in the form of Pascal's curve or screw rather than being spherical. In addition, provision is made such that an angular deviation .alpha. is present between the axis of the femoral throat of the thigh and the rotary axis of the ball of the joint when viewed from the top, such deviation preferably equal to 10.7.degree..+-.3.degree..
