Description
Die Erfindung betrifft eine Bandscheibenprothese für die Halswirbelsäule gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an intervertebral disc prosthesis for the cervical spine according to the generic term of claim 1.
Bei Schädigungen der Bandscheiben, z. B. Bandscheibenvorfall, wird die schadhafte Bandscheibe entfernt und durch eine implantierte Bandscheibenprothese ersetzt. Eine solche Bandscheibenprothese für die Halswirbelsäule ist z. B. aus der WO 98/58604 bekannt. Diese Bandscheibenprothese besteht aus einem metallischen kreiszylindrischen Körper, der zwischen die Wirbelkörper eingesetzt wird. Zur Verankerung in den Wirbelkörpern ist die kraniale Oberfläche und die kaudale Unterfläche des Körpers gezahnt.If the intervertebral discs are damaged, z. B. herniated disc, the damaged disc is removed and replaced by an implanted intervertebral disc prosthesis. Such Intervertebral disc prosthesis for the cervical spine is z. B. known from WO 98/58604. This intervertebral disc prosthesis consists of a metallic circular cylindrical body that between the vertebrae is used. The anchoring in the vertebral bodies is the cranial surface and the caudal under surface of the body serrated.
Weiter ist es bekannt, Bandscheibenprothesen aus einem biokompatiblen Kunststoff zu fertigen, z. B. aus Polyetheretherketon (PEEK).It is also known to have intervertebral disc prostheses to manufacture from a biocompatible plastic, e.g. B. from polyether ether ketone (PEEK).
Der Erfindung liegt die Aufgabe zugrunde, eine Bandscheibenprothese für die Halswirbelsäule zu schaffen, die die natürliche Bandscheibe anatomisch möglichst gut ersetzt und eine hohe Positionsstabilität gewährleistet.The invention is based on the object an intervertebral disc prosthesis for the cervical spine to create the natural Intervertebral disc anatomically possible well replaced and high position stability guaranteed.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Bandscheibenprothese mit den Merkmalen des Anspruchs 1.According to the invention, this object is achieved by an intervertebral disc prosthesis with the features of claim 1.
Vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are in the subclaims specified.
Die erfindungsgemäße Bandscheibenprothese für die Halswirbelsäule weist eine in etwa rechteckige Außenkontur auf mit etwa parallel verlaufenden lateralen Außenflächen und etwa parallel verlaufender ventraler und dorsaler Außenfläche. Die lateralen Außenflächen und die ventrale Außenfläche sind vorzugsweise leicht konvex nach außen gewölbt. Die dorsale Außenfläche ist konkav nach innen gewölbt, sodass ein ausreichender Freiraum für den im Wirbelkanal verlaufenden Duralsack gewährleistet ist. Eine Kollision der Bandscheibenprothese mit dem Duralsack und eine evt. Schädigung des Duralsacks ist dadurch mit hoher Sicherheit ausgeschlossen.The intervertebral disc prosthesis according to the invention for the cervical spine has an approximately rectangular outer contour on with approximately parallel lateral outer surfaces and approximately parallel ventral and dorsal outer surface. The lateral outer surfaces and are the ventral outer surface preferably slightly convex outwards. The dorsal outer surface is concave inward, so that there is sufficient space for the person running in the spinal canal Dural bag guaranteed is. A collision of the intervertebral disc prosthesis with the dural sac and a possible damage the dural sac is therefore excluded with a high degree of certainty.
Die kraniale Oberfläche des Körpers der Bandscheibenprothese ist konvex ausgewölbt, sodass sich diese Oberfläche optimal der konkav gewölbten Deckplatte des Wirbelkörpers anpasst. Die Unterfläche des Körpers ist vorzugsweise ebenfalls leicht konvex ausgewölbt, wobei die Auswölbung der Oberfläche eine stärkere Krümmung, d. h. einen kleineren Krümmungsradius, als die Unterfläche aufweist.The cranial surface of the body the intervertebral disc prosthesis is convex, so that this surface is optimal the concave Cover plate of the vertebral body adapts. The bottom surface of the body is preferably also slightly convex, the bulge of the surface a stronger one Curvature, d. H. a smaller radius of curvature, than the bottom surface having.
Die Oberfläche und die Unterfläche des Körpers weisen eine Zahnung auf, wobei diese vorzugsweise mit pyramidenförmigen Zähnen ausgebildet ist.The surface and the bottom surface of the body have teeth, these preferably being formed with pyramid-shaped teeth is.
Der freie innere Ausschnitt des Körpers folgt in seiner Kontur im Wesentlichen der Außenkontur des Körpers, sodass die Oberfläche und die Unterfläche jeweils mit in etwa konstanter Breite über den gesamten Umfang verlaufen.The free inner cutout of the body follows in its contour essentially the outer contour of the body, so that the surface and the bottom surface each with an approximately constant width over the entire circumference.
Durch diese Gestaltung der Bandscheibenprothese passt sich der scheibenförmige Körper optimal der anatomischen Form der Wirbelkörper an. Die Oberfläche und die Unterfläche, welche die Wirbelkörper abstützen, verlaufen nahe am Außenumfang der Wir beldeckplatten, sodass die Wirbel in dem Bereich abgestützt werden, in welchem die Knochensubstanz des Wirbelkörpers die höchste Stabilität aufweist. Im Bereich des spongiosen inneren Knochenbereichs der Wirbeldeckplatte, der eine geringere Stabilität und Tragfähigkeit aufweist, ist der Körper der Bandscheibenprothese durch den inneren Ausschnitt ausgespart. Dadurch wird in dem inneren Bereich, der zur Abstützung nicht wesentlich beitragen kann, Material eingespart, sodass das Gewicht der Bandscheibenprothese möglichst gering bleibt. Die Bandscheibenprothese bewirkt eine gleichmäßig über den Umfang verteilte Abstützung der Wirbel in deren tragfähigem Knochenbereich. Die rechteckige Form der Außenkontur und der Innenkontur ergeben zusammen mit der Zahnung eine hohe Verdrehsicherheit.This design of the intervertebral disc prosthesis fits the disc-shaped body optimally to the anatomical shape of the vertebral body. The surface and the bottom surface, which are the vertebral bodies support, run close to the outer circumference we cover plates so that the vertebrae are supported in the area in which the bone substance of the vertebral body has the highest stability. In the area of the cancellous inner bone area of the vertebral cover plate, which is less stability and load capacity is the body of the intervertebral disc prosthesis through the inner cutout. This will result in the inner area not being used for support material can significantly contribute to reducing weight the intervertebral disc prosthesis if possible remains low. The intervertebral disc prosthesis causes an even over the Scope of distributed support the vortex in their viable Bone area. The rectangular shape of the outer contour and the inner contour together with the toothing result in a high degree of security against rotation.
Die Bandscheibenprothese wird vorzugsweise in zwei Ausführungen hergestellt. In einer Ausführung verlaufen die Oberfläche und die Unterfläche im Wesentlichen parallel zueinander, während in der anderen Ausführung die Oberfläche und die Unterfläche keilförmig zueinander verlaufen, wobei sich der Abstand von Oberfläche und Unterfläche von dorsal nach ventral vergrößert. Durch diese beiden Ausführungen ist eine optimale Anpassung an die anatomischen Gegebenheiten der zu ersetzenden Bandscheibe möglich.The intervertebral disc prosthesis is preferred in two versions manufactured. Run in one execution the surface and the bottom surface essentially parallel to each other, while in the other embodiment the surface and the bottom surface cuneiform to each other, the distance between the surface and undersurface enlarged from dorsal to ventral. By these two designs is an optimal adaptation to the anatomical conditions of the intervertebral disc to be replaced.
Die Bandscheibenprothese wird vorzugsweise aus einem biokompatiblen Kunststoff mit geeigneten mechanischen Eigenschaften gefertigt, wobei sich Polyetheretherketon (PEEK) besonders eignet.The intervertebral disc prosthesis is preferred made of a biocompatible plastic with suitable mechanical Properties manufactured, with polyether ether ketone (PEEK) particularly suitable.
