Abstract

Die Anmeldung betrifft eine Hüftgelenkprothese mit einem Schaft (1), auf dessen Schaftkopf (22) ein Kugelkopf (2) befestigt ist, der wiederum in der Kalotte eines Pfanneneinsatzes drehbar eingesetzt ist, und der Pfanneneinsatz mit einer Hüftpfanne gekoppelt ist, wobei der Schaft (1) in den Oberschenkelknochen und die Hüftpfanne in den Beckenknochen implantierbar sind. Hierbei wird zur Vermeidung der Übertragung von Schwingungen vorgeschlagen, dass an den Koppelstellen des Schaftkopfes (22) mit dem Kugelkopf (2) und/oder des Pfanneneinsatzes mit der Hüftpfanne Dämpfungselemente aus einem schwingungsdämpf enden Material angeordnet sind.
