Abstract
A modular hip joint prosthesis system has an intermediate element which has an inner surface for receiving a prosthesis neck and an outer surface, a joint ball head which is embodied as a plug head having an inner surface associated with the outer surface of the intermediate element, and a bipolar joint socket in which an inlay is received in an outer shell in a freely moving manner and which has a ball receiver which is associated with the joint ball head, configured such that the joint ball head can be received in a movable manner. A premounted joint prosthesis system part for a modular joint prosthesis system and a sterile article are also provided.
