Description
Die Erfindung betrifft eine Hüftgelenkprothese nach dem Oberbegriff des
Anspruchs 1.
Aus dem Gebrauchsmuster FR 2 715 828 ist eine Hüftgelenkprothese mit drei
ineinanderliegenden kugelförmigen Kalotten bekannt.
Die kugelförmige Außenkalotte besteht aus einem biokompatiblen, starren
Werkstoff wie INOX-Stahl oder Titan, welche an der Außenseite mit radialen
Unebenheiten zur Befestigung in der Gelenkpfanne des Beckenknochens
versehen ist.
Die kugelförmige Innenkalotte besteht aus einem harten, biokompatiblen
Werkstoff wie beispielsweise Aluminiumoxidkeramik oder einem ähnlichen
Material, mit einem niedrigen Reibungskoeffizienten in bezug auf das Material,
aus dem der Kopf des daran anschließenden Oberschenkelelements besteht.
Die kugelförmige Zwischenkalotte besteht aus einem halbstarren Material wie
Kunststoff, insbesondere Polyethylen.
Ein Problem bei Zwischenkalotten oder Zwischenelementen aus Kunststoff ist,
daß diese durch hohen Abrieb Osteolyse auslösen können, wenn keine
formschlüssige Verbindung zwischen der Gleitschale und dem Kunststoff-Mantel
besteht. Andererseits kann eine formschlüssige Verbindung durch Schmelzen
des Kunststoff-Mantels erreicht werden, wie in EP 0 554 214 A1 beschrieben.
Dies kann jedoch zur Zerstörung der Molekülstruktur führen und damit Verschleiß
auslösen.
Der Erfindung liegt die Aufgabe zugrunde, eine Hüftgelenkprothese nach dem
Oberbegriff des Anspruchs 1 derart zu verbessern, daß die Gefahr von Osteolyse
weitgehend aufgehoben ist.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des
Anspruchs 1 gelöst.
Dadurch, daß das Zwischenelement aus einem Oberteil und einem Unterteil
besteht, daß Oberteil und Unterteil miteinander verbindbar sind und daß der
Pfanneneinsatz zwischen Oberteil und Unterteil verankert ist, wird der Verschleiß
des Zwischenelements vermieden und dadurch die Gefahr von Osteolyse
vermindert.
In bevorzugter Ausführungsform ist der Pfanneneinsatz allseitig bis auf seine
kugelförmige Ausbuchtung vom Zwischenelement, d. h. dem Ober- und Unterteil
ummantelt, so daß keine freien Steilen vorhanden sind, an denen ein Abrieb
auftreten kann.
Die Verbindung des Oberteils mit dem Unterteil kann auf die verschiedensten
Arten durchgeführt werden. Als zweckmäßig erweisen sich Schraubver
bindungen über ein Gewinde, Schnappverbindungen, Verstiftungen, Kleben oder
Schweißen.
Der Pfanneneinsatz kann aus Metall oder Keramik hergestellt sein. Bevorzugt
eignet sich diese Erfindung für alle keramischen Pfanneneinsätze.
Zweckmäßigerweise sind im Pfanneneinsatz und im angrenzenden Unterteil
gegenüberliegende Aussparungen vorgesehen, in denen zur Rotationssicherung
Einsätze eingebracht sind. Hierdurch sitzt der Pfanneneinsatz in seiner Lage
fixiert im Zwischenelement. Die Einsätze können z. B. Stifte, Nutensteine bzw.
Paßfedersysteme oder Keile sein und z. B. aus Metall oder Kunststoff gefertigt
sein. Zur besseren Fixierung füllen die Einsätze die Aussparungen
vorteilhafterweise vollständig aus.
Weitere Merkmale der Erfindung ergeben sich aus den Figuren, die nachfolgend
beschrieben sind.
Fig. 1 zeigt angedeutet im Schnitt eine metallische Prothesenschale 1, die in die
nicht gezeigte Gelenkpfanne eines Beckenknochens implantierbar ist. Zur
besseren Verankerung sind an der Außenseite der Prothesenschale 1 Rippen
oder ein Gewinde 10 angeordnet. In die Prothesenschale 1 ist ein
Zwischenelement 4 aus Kunststoff eingesetzt, das wiederum einen keramischen
Pfanneneinsatz 2 ummantelt.
Das Zwischenelement 4 ist mit seiner äußeren Kontur an die Form der
Prothesenschale 1 angepaßt und besteht aus einem Oberteil 5 und einem
Unterteil 6.
Das Unterteil 6 ist zum Oberschenkelknochen gewandt und weist eine
Ausbuchtung 11 zur Aufnahme des Pfanneneinsatzes 2 auf. Der Pfanneneinsatz
2 ist dabei bis auf seine kugelförmige Ausbuchtung 3 vollständig vom
Zwischenelement 4 ummantelt. Besonders hervorzuheben ist, daß das Oberteil 6
auch die der Ausbuchtung 3 benachbarte Auflagefläche 12 abdeckt. Das Oberteil
5 deckt den Pfanneneinsatz 2 auf seiner Rückseite ab und ist mit dem Unterteil 6
auf die verschiedensten Arten und Weisen verbunden. Die kugelförmige
Ausbuchtung 3 dient zur Aufnahme des Kopfes eines Oberschenkelelements.
Fig. 1 zeigt eine Ausführungsform für den Fall, daß der Patient eine Displasie
hat, d. h. daß der Pfanneneinsatz 2 unsymmetrisch in die Prothesenschale 1
eingebaut werden muß. Fig. 2 zeigt einen symmetrischen Einbau des
Pfanneneinsatzes 2 in der Prothesenschale 1.
Die Fig. 3 bis 5 zeigen verschiedene Verbindungen des Oberteils 5 mit dem
Unterteil 6. Diese Verbindung ist in den Fig. 1 und 2 mit X bezeichnet. In Fig.
3 ist das Oberteil 5 mit dem Unterteil 6 über ein Gewinde 7 verbunden bzw.
verschraubt. Fig. 8 zeigt eine Schnappverbindung 8.
Hierzu sind am Oberteil 5 und Unterteil 6 einzelne kleine Erhebungen
angeordnet, die beim Einpassen des Oberteils 5 in das Unterteil 6
ineinandergreifen und so eine gute Verbindung schaffen. Fig. 5 zeigt eine
Verstiftung 9. Hierzu ist im Unterteil 6 und Oberteil 5 eine Bohrung 13
eingebracht, in die ein durchgehender Stift 14 eingebracht ist.
Der Pfanneneinsatz 2 besteht aus einer Keramik, wie z. B. einer
Aluminiumoxidkeramik. Es ist jedoch auch jede andere Keramik einsetzbar.
Die Fig. 6 und 7 zeigen Ausführungsformen ähnlich der in den Fig. 1 und 2
gezeigten, jedoch sind zusätzlich im Pfanneneinsatz 2 und im angrenzenden
Unterteil 6 gegenüberliegende Aussparungen 15 vorgesehen, in denen zur
Rotationssicherung Einsätze 16 eingebracht sind. Diese Einsätze 16 füllen die
Aussparungen 15 vollständig aus und bestehen aus Metall oder Kunststoff.
Fig. 8 zeigt einen Schnitt entlang der Linie A-A und Fig. 9 einen Schnitt entlang
der Linie B-B in Fig. 7. In Fig. 8 ist ein Stift 17 und in Fig. 9 ein im Querschnitt
rechteckiger Nutenstein 18 in die Aussparung 15 eingebracht.
Mit diesen Einsätzen 16 ist eine Verdrehsicherung des Pfanneneinsatzes 2 im
Zwischenelement 4 erreicht.
