Abstract
A protrusio cup for implantation in the acetabulum, including an acetabular cup and a protrusio shell mounted on the acetabular cup by interlocking grooves and projections. The acetabular cup has a hemispherical bearing surface which terminates in a part-conical surface. The bearing surface and the part-conical surface are rotated through an angle to reduce the likelihood of dislocation and to increase the range of motion.
