An acetabular cup (11) for use with a plastic socket bearing is provided. The cup includes a circular aperture (19) having a stepped configuration. A domed disc (13) is inserted in the aperture (19) and deformed to seal the aperture (19). In this way, plastic particles, which are generated by wear of the beating dying use, are prevented from migrating through the aperture (19) to the bone surrounding and supporting the prosthesis.
Cupule acétabulaire (11) s'utilisant avec un support de cavité articulaire en plastique et comprenant une ouverture circulaire (19) à configuration étagée et un disque en forme de dôme (13) qui s'insère dans l'ouverture circulaire (19) et se déforme de façon à obturer l'ouverture (19). Ainsi, les particules en plastique provenant de l'usure du support pendant l'utilisation ne peuvent pas migrer à travers l'ouverture (19) ni atteindre l'os qui entoure et supporte la prothèse.
