Description
Die Erfindung bezieht sich auf Prothesen, die über einen Metallstab in einem Knochenschaft befestigt werden sollen.
Solche Prothesen werden z.B. an Hüftgelenken verwendet.
In der amerikanischen Patentschrift Nr. 3 740 769 ist ein Metallstab zum Einsatz in den OberSchenkelhalsknochen für
eine Hüftprothese beschrieben, der einen kreuzförmigen Querschnitt aufweist und somit vier in Längsrichtung verlaufende Vertiefungen
besitzt, die mit mit Hilfe von dehydratisiertem Knochenpulver verklebten Knochenstückchen gefüllt werden, die sich mit dem
verbliebenen Knochengewebe fest verbinden sollen und auf diese Weise für eine einwandfreie Befestigung des Metallstabs im Oberschenkelhalsknochen
sorgen sollen. Man erreicht mit dieser Anordnung jedoch nicht an allen Stellen, an denen das Knochenmate-
609884/0312
2 6 2 8 2 R 4
rial mit dem Metallstab in Berührung steht, eine zufriedenstellende
Befestigung; außerdem entsteht hierbei eine kompakte Struktur, die keine für die Durchdringung mit Blutgefäßen zur
Blutversorgung des sich bildenden Knochengewebes notwendige Lücken aufweist, so daß die nachwachsenden Knochenzellen wegen
der schlechten Blutversorgung relativ kurzlebig sind und sich an manchen Stellen im Kontakt mit dem Metallstab ein Bindegewebe
bildet, das keine ausreichende Haftung des Stabs im Knochen gewährleistet. Man kann auf diese Weise also keine sehr stabile
und starre Befestigung des Metallstabs im Knochen erreichen. Wenn sich aber der Metallstab geringfügig im Knochengewebe bewegen
kann, dann führen diese Bewegungen zu einer erneuten Zerstörung von Knochengewebe, so daß nach einer gewissen Zeit
der Metallstab seine feste Bindung mit dem Knochen verliert. Der Patient muß sich daraufhin erneut operieren lassen, damit
der Metallstab wieder im Knochen befestigt wird.
Ziel der Erfindung ist es, diese Nachteile zu beheben und einen Metallstab zu schaffen, der in einen Knochenschaft für
eine Prothese eingesetzt werden kann und ein Nachwachsen von Knochenzellen auf seiner Oberfläche und folglich eine feste und
dauerhafte Verbindung mit dem Knochenschaft ermöglicht, ohne daß der Metallstab im Knochenschaft gedreht werden kann, wobei
gleichzeitig eine ausgezeichnete Korrosionsfestigkeit dadurch gewährleistet sein soll, daß die Oberfläche des Metallstabs glatt
bleibt.
Dieses Ziel wird durch den im Hauptanspruch definierten Metallstab erreicht. Bevorzugte Ausführungsformen der Erfindung
sind in den Unteransprüchen gekennzeichnet.
609884/0312
Nachfolgend wird ein Ausführungsbeispiel unter Bezugnahme auf die beiliegenden Figuren näher beschrieben.
Pig. la zeigt in Seitenansicht einen erfindungsgemäßen
Metallstab, der von einem Metallgitter umgeben ist, wobei letzteres teilweise entfernt dargestellt ist.
Fig. Ib zeigt einen Schnitt durch den Metallstab aus
Fig. la.
Fig. 2 zeigt den Y-fö|trmigen Querschnitt eines weiteren
erfindungsgemäßen Metallstabs.
Der Metallstabιgemäß den Fig. la und Ib, der in einen
Oberschenkelhalsknochen eingesetzt werden soll, ist mit dem
Gelenkkugelkopf 2 über einen Hals 3A verbunden. Dieser ist mit einem Verbindungsteil 3B versehen, das im Innern des Kopfs 2
durch ein geeignetes Mittel, beispielsweise durch Einschrauben in ein auf der Innenseite des Kopfes 2 um ein in diesen Kopf
eingearbeitetes Sackloch herum geschweißtes Metalleinsatzteil, befestigt ist. Der Stab selbst weist einen kreuzförmigen Querschnitt auf und besitzt vier Rippen 4, 5, 6, 7, die zwischen
sich Vertiefungen 8, 9, 10 und 11 aufweisen. Auf die Rippen 4, 5, 6, 7 ist ein Gitter 12 aufgeschweißt, beispielsweise durch
Elektronenschweißen. Dieses Gitter hat Löcher 15, deren Durchmesser mindestens 0,3 mm beträgt und die für den Blutkreislauf den Weg in die Vertiefungen 8, 9, 10 und 11 freigeben. Die Vertiefungen sind mit einem Material gefüllt, das das Nachwachsen von Knochenzellen begünstigt, beispielsweise mit einem biologisch abbaubaren organischen Stoff, der in die Vertiefungen eingegossen wird; bei diesem organischen Stoff kann es sich beispielsweise um Polymilchsäure oder Polyglykolsäure, um ein Polylaktid

handeln. Dieses Material kann aber auch aus Trikalziuraphosphat oder mono- oder polykristallinenFasern, insbesondere Kohlenstofffasern,
bestehen.
Der in Fig. 2 dargestellte Metallstab weist einen Y-förmigen
Querschnitt mit einer verdickten Basis 20 und zwei Rippen 21 und 22 auf. Die länglichen Vertiefungen 24, 25, 26
sind mit einem am Stab angeschweißten Metallgitter 23 versehen. Vor dem Befestigen des Metallgitters kann auf den Metallstab
eine Aluminiumoxydbeschichtung durch Plasmabeschuß aufgebracht werden. Das Metallgitter kann mit einem biologisch abbaubaren,
das Knochenzellenwachstum begünstigenden organischen Stoff imprägniert sein.
Die Erfindung ist auch auf Stäbe anwendbar, die in Knochenschäfte für andere Prothesen als die Hüftprothese eingesetzt
werden, insbesondere auf Stäbe, die in den Humerus für Schulterprothesen, in den Oberschenkelhalsknochen und den Schienbeinknochen
bei Knieprothesen und in den Humerus und Radius bei Ellenbogenprothesen eingesetzt werden.
