摘要：
A cap used during the insertion of an acetabular cup prosthesis. The cap includes impaction plate having an upperside and an underside. The impaction plate includes a plurality of separate sectors mutually connected at a connection point on the impaction plate by flanges. Each sector includes interlocking elements which in use enable the impaction plate to be connected to an introduction tool. The cap also includes at least one lug extending downwardly from the underside of each sector. The lug is located at the portion of the underside of the impaction plate which will in use enable the lug to be interconnected with a corresponding recess on an internal wall, an external wall or a rim of a prosthesis.
