Description

Die Erfindung geht aus von einer Hüftgelenkpfanne, wie sie im Oberbegriff des Anspruches 1 beschrieben bzw. aus dem DE-GM 73 13 647 bekannt ist.
Diese Hüftgelenkpfanne besteht aus Kunststoff und weist eine halbkugelförmige äußere Oberfläche auf, die mit radial nach außen gerichteten Zapfe»! zwecks Befestigung in der natürlichen Hüftgelenkpfanne versehen ist. Außerdem ist ein halbkreisförmiger Stahldraht vorgesehen, der sich quer über die äußere Oberfläche erstreckt. Im Randverlauf ist ein etwas überstehender ovaler Flansch vorgesehen.
Nachteilig bei dieser Hüftgelenkpfanne ist vor allem, daß keine gleichmäßige Anlage am Hüftgelenkknochen gewährleistet ist. Außerdem kann der Zement ausbrökkeln, wenn eine ungleichmäßige Belastung auftritt. Für jedes natürliche Hüftgelenk, das sich von anderen erheblich unterscheiden kann, muß eine paßgerechte Hüftgelenkpfanne von Fall zu Fall hergestellt werden, gleichbedeutend mit einem hohen Kostenaufwand.
Aufgabe der Erfindung ist die Schaffung einer künstlichen Hüftgelenkpfanne, die für verschiedene Größen der natürlichen rechten und linken Hüftgelenkpfanne durch Beschneiden anpaßbar ist.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.
Durch diese erfindungsgemäße Ausführungsform ist gewährleistet, daß der Flansch formschlüssig mit seinem Rand gleichmäßig an der vorbereiteten natürlichen Pfanne anliegt Ferner ist gewährleistet, daß diese Hüftgelenkpfanne für jedes auch noch so deformierte Hüftgelenk verwendet werden kann, so daß Sonderfertigungen entfallen. Der behandelnde Arzt kann sich nämlich während der Operation die Hüftgelenkpfanne paßgerecht zuschneiden.
Die Erfindung ist an Beispielen in der Zeichnung dargestellt und beschrieben, und zwar zeigt
F i g. 1 eine Aufsicht auf eine künstliche Hüftgelenkpfanne,
F i g. 2 eine Seitenansicht gemäß F i g. 1,
Fig.3 im Querschnitt eine in einen Hüftknochen eingesetzte künstliche Hüftgelenkpfanne,
F i g. 4 eine Aufsicht auf eine künstliche Hüftgelenkpfanne ähnlich der nach F i g. 1 und
F i g. 5 eine Seitenansicht nach F i g. 4.
Der Flansch 14 und die äußere Oberfläche der Hüftgelenkpfanne aus Kunststoff (Fig.2, 3) bilden einen spitzen Winkel zueinander. Der Flansch 14 ist (siehe Fig. 1) asymmetrisch ausgebildet Etwa über den halben Umfang des Randes ist der Flansch 14 breiter als über den restlichen Umfang.
Die künstliche Hüftgelenkpfanne 12 weist eine kugelförmige Aufnahmeöffnung 13 für einen Oberschenkelprothesenkopf auf. Als Material für diese Hüftgelenkpfanne 12 kann beispielsweise verdichtetes Polyäthylen gewählt werden; sie ist im Spritzgußverfahren herstellbar. Die mit Zement 21 ausgekleidete und durch Bearbeiten vorbereitete natürliche Pfanne nimmt die künstliche Hüftgelenkpfanne 12 satt auf; die Hüftgelenkpfanne 12 stützt sich mit ihrem Flansch 14 dabei am Hüftknochen 1 ab. Im Hüftknochen 1 ist nämlich die natürliche Hüftgelenkpfanne bearbeitet worden und besteht aus einem halbkugelförmigen Teil 10, das in eine Erweiterung 11 übergeht. Die künstliche Hüftgelenkpfanne 12 liegt bei 23 am Hüftknochen 1 an. Durch die Berührung zwischen dem Flansch 14 und der Wand der Erweiterung 11 ist die künstliche Hüftgelenkpfanne 12 gegen Hin- und Herbewegen festgelegt, so
4& daß ein Ablösen des Zementes 21 nicht zu befürchten ist. Außerdem verschließt der Flansch 14 den innen eingebrachten Zement 21, übt einen Druck auf den Zement 21 aus, so daß das satte Anliegen der künstlichen Hüftgelenkpfanne in dem ausgearbeiteten
•t5 Teil des Hüftknochens 1 gewährleistet ist. Da der Flansch 14 etwas elastisch ist kann überschüssiger Zement 24 austreten, der vor dem Abbinden zweckmäßig entfernt wird.
Der halbbiegsame Flansch 14 (siehe Fig. 1), der die beiden Lappen 15, 16 aufweist, kann dadurch seine asymmetrische Form erhalten, daß nur ein Lappen 26 (F i g. 4/5) vorgesehen ist.
Durch die am Flansch 14 vorgesehenen Schneidlinien 17 bis 20 (Fig. 1) hat der Arzt Richtlinien, wie er die Innenpfanne 12 zuschneiden kann. Wird die Pfanne in ein rechtes Hüftgelenk eingesetzt, dann wird das Rohteil entlang der Linie 19, und sofern das Hüftgelenk normal geformt ist, entlang der Linie 18 beschnitten. Für linke Hüftgelenke gelten sinngemäß die Linien 20 und 17.1st das Hüftgelenk größer als normal, dann kann der Schnitt zwischen den Linien 18 und 20 und der Kante der Lappen 15 und 16 liegen.
