Abstract
The plastic cup-comprising member and the hemispherical shell of the two-part acetabular cup prosthesis are secured relative to one another in snap-fitted manner. The plastic member is centered and guided during pressing-in via a centering pin and concentric annular web on the plastic member. The annular web is also locally deformable so as to deform against a screw head during pressing-in without the annular web losing its centering guiding action.
