Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Korrektur und dynamischen Stabilisierung von Knochen oder Knochenfragmenten, insbesondere Rückenwirbelkörpern.The The present invention relates to a device for correction and dynamic stabilization of bones or bone fragments, in particular Spinal vertebrae.
Stand der TechnikState of the art
Bei der Behandlung von Bandscheibendefekten ist die operative Entfernung der defekten Bandscheibe und die Versteifung des Bandscheibenzwischenraums mit den beiden Wirbelkörpern eine bekannte Methode. Dies führt jedoch zu dem Resultat, dass die an den versteiften Abschnitt angrenzenden Segmente der Wirbelsäule unnatürlich belastet werden und keine Beweglichkeit mehr im entsprechenden Wirbelsäulensegment besteht. Eine weitere Methode ist nach der Entfernung der Bandscheibe eine Bandscheibenprothese in den Zwischenwirbelraum zu setzen. Jedoch ist eine Simulierung der Eigenschaften einer natürlichen Bandscheibe noch unbefriedigend.at The treatment of disc defects is surgical removal the defective disc and the stiffening of the intervertebral disc space with the two vertebral bodies a known method. This However, leads to the result that the stiffened Section adjacent segments of the spine unnatural be burdened and no mobility in the corresponding spine segment consists. Another method is one after removal of the disc Put the intervertebral disc prosthesis in the intervertebral space. however is a simulation of the properties of a natural one Intervertebral disc still unsatisfactory.
Der Stand der Technik zeigt, dass die Vorteile von dynamischen Wirbelsäulenstabilisierungen zunehmend bekannter werden. Aus diesem Grund haben bereits verschiedene Erfinder solche Systeme entwickelt und offengelegt. Diese Erfindungen unterliegen jedoch Nachteilen, die anhand folgender Beispiele dargestellt werden.Of the Prior art shows that the benefits of dynamic spine stabilization become increasingly known. For this reason already have different Inventors developed and disclosed such systems. These inventions However, there are disadvantages, which are illustrated by the following examples become.

Aufgabenstellungtask
Es ist die Aufgabe der Erfindung eine dynamisch wirkende Stabilisierungseinrichtung, insbesondere für benachbarte Wirbel bereitzustellen, die nach ihrer Implantation eine starke Annäherung an die physiologischen Bewegungsmöglichkeiten der gesunden Wirbelsäule gewährleistet.It the object of the invention is a dynamically acting stabilizing device, especially for adjacent vortices that provide after their implantation a strong approximation to the physiological Movement possibilities of the healthy spine guaranteed.
Die Aufgabe wird gelöst durch eine Stabilisierungseinrichtung gemäß Patentanspruch 1. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Insbesondere ist gemäß der vorliegenden Erfindung ein geschlossenes modular individualisierbares System zur Unterstützung bzw. Einschränkung der Flexion, Extension, Seitneigung und Rotation von benachbarten Wirbelkörpern, d. h. insgesamt sechs Freiheitsgraden von Wirbelkörpern, vorgesehen.The Task is solved by a stabilization device according to claim 1. Further developments of the invention are given in the subclaims. In particular according to the present invention, a closed modular individualized system for supporting or Restriction of flexion, extension, lateral tilt and rotation of adjacent vertebral bodies, d. H. a total of six degrees of freedom of vertebral bodies, provided.
