Abstract
A modular hip implant is disclosed that includes a base member that is to be attached to a pelvic bone, and a cup for accommodating a hip joint prosthesis. The base member is provided with fasteners for mounting the base member on the pelvic bone as well as a concave accommodation portion for the cup. The cup has a convex outer shape which is complementary to the accommodation portion such that the radii of curvature determining the concave accommodation portion and the convex outer form essentially correspond to each other and the cup can be attached within the base member. The base member and/or the cup include adjustment means for adjusting the position of the cup relative to the base member. The invention allows the inclination and anteversion to be adjusted by arranging the cup in the base.
