Description

Sprunggelenk-Endoprothese
Zum Ersatz des Sprunggelenks ist eine Endoprothese bekannt, die aus einer mit dem Sprungbein zu verbindenden Komponente, einer mit dem Schienbein zu verbindenden Komponente und einem Zwischenteil besteht (Prospekt "LINK S.T.A.R. Totale Sprunggelenkprothese [H. Kofoed] der Firma Waldemar Link (GmbH & Co.), Hamburg). Die Sprungbeinkomponente und der Zwischenteil wirken über Gleitflächen zusammen, die Beugung und Streckung in der Sagittalebene ermöglichen. Die Schienbeinkomponente und der Zwischenteil bilden zusammenwirkende Gleitflächen, die eine Rotation um die Hochachse erlauben. Sie können eben ausgeführt sein, um Ausgleichsbewegungen in AP- und LM- Richtung zu ermöglichen. Die Stabilisierung geschieht durch den natürlichen Bandapparat.
Die ober- und unterseitigen Gleitflächen des Zwischenteils sind bei der bekannten Prothese in der Frontalebene parallel zueinander orientiert. Dies ist insofern konsequent, als die natürlichen Gleitflächen des Sprungbeins und des Schienbeins durch die prothetischen Gleitflächen ersetzt werden sollen, ohne daß damit eine Richtungsänderung verbunden ist. Jedoch hat sich gezeigt, daß die lateralen und medialen Bänder des Gelenks nach der Operation nicht selten eine unterschiedliche Spannung aufweisen, woraus Beschwerden resultieren können.
Die Erfindung ermöglicht es, diese Unausgewogenheit dadurch zu vermeiden, daß ein Zwischenteil zur Verfügung gestellt wird, der in der Frontalebene keilförmig ausgebildet ist. Die in der Frontalebene liegenden Richtungsachsen der Gleitflächen laufen nicht parallel zueinander, sondern in einem Win- kel, der normalerweise zwischen 1° und 12° liegt. Je nach den vorgefundenen Verhältnissen kann der Arzt bestimmen, ob und welchen Winkel er zwischen den Gelenkachsen durch Auswahl des geeigneten Zwischenstücks vorsehen will. Dies kann gegebenenfalls auch intraoperativ geschehen.
Damit der Zwischenteil hinsichtlich seiner Keilform richtig orientiert bleibt, wird seine Ausrichtung zweckmäßigerweise zwangsweise vom Sprungbein oder vom Schienbein her festgelegt, indem die zusammenwirkenden Gleitflächenpaare entspre- chend richtungsbestimmend ausgebildet sind. Dazu ist besonders das Gelenk zwischen dem Sprungbein und dem Zwischenteil geeignet.
Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnung erläutert, die ein vorteilhaftes Ausführungsbeispiel veranschaulicht. Es zeigen: Fig. 1 einen Sagittalschnitt durch das mit der Prothese versorgte Gelenk, Fig. 2 die Prothese perspektivisch aufgefächert, Fig. 3 einen Frontalschnitt durch den Zwischenteil und
Fig. 4 einen perspektivischen Blick in die Anordnung der knochen und zugehörigen Prothesenteile vor dem Einsetzen des Zwischenteils
Zwischen dem Schienbein 1 und dem Sprungbein 2 ist die Pro- these anzuordnen, die aus der Schienbeinkomponente 3, der Sprungbeinkomponente 4 und dem Zwischenteil 5 besteht. Die Schienbeinkomponente 3 weist einen plattenförmigen Teil 6 auf, dessen Unterseite 7 eine ebene Gleitfläche bildet. Vorsprünge 8 dienen zur Befestigung in entsprechenden Resekti- onsausnehmungen 9 des Schienbeins 1.
Die Sprungbeinkomponente 4 bildet eine konvex gewölbte Gleitfläche 10, die zylindrisch oder kegelig ausgebildet sein kann. Sie trägt eine Rippe 11, die in der Richtung der Rela- tivbewegung des Zwischenteils bei der Beuge- und Streckbewegung liegt. Ferner weist die Sprungbeinkomponente seitliche Facetten 12 zum Zusammenwirken mit entsprechenden Gleitflächen des Schienbeins 1 und des Wadenbeins 13 auf.
Der Zwischenteil 5 besitzt eine Ebene, zur Gleitfläche 7 passende Oberseite 15 und eine unterseitige Gleitfläche 16, die kongruent zur Gleitfläche 10 der Sprungbeinkomponente 4 ausgebildet ist. Sie enthält eine Nut 17 zur Aufnahme der Rippe 11. Dadurch wird der Zwischenteil 5 seitlich im Verhältnis zur Sprungbeinkomponente 4 geführt. Nur Beuge- und Streckbewegungen sind ihm erlaubt.
Die Komponenten 3 und 4 bestehen zweckmäßigerweise aus Metall und der Zwischenteil 5 aus gleitgünstigem Kunststoff wie Po- lyethylen. Jedoch sind auch andere Werkstoffe mit hinreichender Festigkeit und Gleitfähigkeit verwendbar, beispielsweise Keramik. In Folge der kongruenten Form der Gleitflächen 10 und 16 sowie durch die Rippe 11 im Zusammenwirken mit der Nut 17 ist der Zwischenteil 5 bezüglich der Hochachse gegenüber der Sprunggelenkkomponente 4 nicht drehbar. Seine Ausrichtung ist also durch diejenige der Sprungbeinkomponente festgelegt. Während die gezeigte Ausführungsform derartige Rotationsbewegungen vollständig ausschließt, sind auch Ausführungen denkbar, in denen sie durch die Ausbildung der Gleitflächen le- diglich gehemmt ist, indem diese beispielsweise elipsoidisch ausgebildet sind.
Im Frontalschnitt gemäß Fig. 3 ist der Zwischenteil keilförmig ausgebildet. Seine obere Gleitfläche 15 schließt mit der Richtung der unteren Gleitfläche 16 einen Keilwinkel 18 ein, der vorzugsweise zwischen 1° und 12° liegt. In den meisten Fällen liegt er zwischen 3° und 8°.
Sobald der Operateur, wie es in Fig. 4 gezeigt ist, die Schienbeinkomponente 3 und die Sprungbeinkomponente 4 implantiert hat, kann er mittels geeigneter Instrumente feststellen, ob deren Gleitflächen 7 bzw. 10 in LM-Richtung bei gespannten Seitenbändern parallel oder winklig zueinander verlaufen. Dem entsprechend wählt er einen geeigneten Zwischen- teil 5 aus.
