Abstract
An acetabular cup for use with a plastic socket bearing is provided. The cup includes a circular aperture having a stepped configuration. A domed disc is inserted in the aperture and deformed to seal the aperture. In this way, plastic particles, which are generated by wear of the bearing during use, are prevented from migrating through the aperture to the bone surrounding and supporting the prosthesis.
