Abstract
An acetabular cup assembly includes a metal shell component and a plastic bearing insert capable of assembly interoperatively, the metal shell component first being secured in position within an acetabulum and then the plastic bearing insert being receivable within the shell component, first at a preliminary axial position for ascertainment of the circumferential position of the bearing insert and the orientation of the bearing face of the bearing insert relative to the shell component and then at a fully-seated axial position wherein the bearing insert is permanently captured in the shell component, the bearing insert being readily withdrawn from the preliminary axial position for circumferential repositioning to attain appropriate orientation of the bearing face prior to capturing the bearing insert within the shell component.
