Abstract
Description
Spondylodese-StabilisatorSpinal fusion stabilizer
Die Erfindung betrifft einen Spondylodese-Stabilisator für die Fixierung der relativen Lage zweier unmittelbar benachbarter Wirbel zueinander.The invention relates to a spinal fusion stabilizer for fixation the relative position of two immediately adjacent vertebrae to each other.
Bei den bisherigen Konstruktionen von Spondylodese-Stabilisatoren sind zwei grundsätzlich verschiedene Bauarten zu unterscheiden. Bei dem einen Konstruktionskonzept benutzt man sogenannte Harrington-Stäbe; das sind gerillte Stäbe, die an je einem gesunden Wirbel oberhalb und unterhalb der zu stabilisierenden Wirbel mit Hilfe von Haken am Wirbelbogen eingedie hangt wadin,um/dazwischen liegenden Wirbel zu distrahieren.In the previous designs of spinal fusion stabilizers a distinction must be made between two fundamentally different types. With one construction concept so-called Harrington sticks are used; these are grooved bars, each attached to one healthy vertebrae above and below the vertebrae to be stabilized with the help by hooks on the vertebral arch which hangs wadin to / between vertebrae distract.
Für eine Kompression einer Anzahl Wirbel werden bei diesem Konzept Gewinde-/stangen in Verbindung mit den erwähnten Haken verwendet.With this concept, a number of vertebrae are compressed Threaded rods used in conjunction with the hooks mentioned.
Mindestens einer dieser Haken ist dabei mit einer Gewindemutter verbunden (Hackenbroch und Witt: Orthopädischchirurgischer Operationsatlas, Band III, Seite 65 und 127, Stuttgart, 1974). Ebenso wie andere Konstruktionen, bei denen über die Höhe mehrerer Wirbel wirkende Federn benutzt werden, ist es mit diesen Stäben nicht möglich, unmittelbar benachbarte Wirbel direkt gegeneinander zu fixieren. Darüberhinaus werden durch diese Stäbe und Federn, d.h. genauer ihre Haken, mit denen sie an gesunden Wirbeln befestigt werden, noch gesunde Teile der Wirbelsäule in Mitleidenschaft bezogen bzw. müssen für die Anwendung dieser Stabilisatoren in der Nähe der ruhigzustellenden Wirbelgelenke gesunde Wirbel für die Verankerung vorhandensein.At least one of these hooks is connected to a threaded nut (Hackenbroch and Witt: Orthopädischchirurgischer Operationsatlas, Volume III, page 65 and 127, Stuttgart, 1974). As well as other constructions where the If springs acting at the height of several vertebrae are used, these rods are not possible to fix directly adjacent vertebrae against each other. Furthermore are made by these rods and springs, i.e. more precisely their hooks with which they are healthy Vertebrae are attached, but healthy parts of the spine are still affected related or must for the application of these stabilizers in the vicinity of the immobilized Vertebral joints healthy vertebrae for anchoring are present.
Weiterhin sind aus Platten oder Schienen bestehende Konstruktionen bekannt, die direkt an den zu fixierenden Wirbeln, beispielsweise durch Schrauben und/oder Metellstifte, be- festigt werden (Operationsatlas, Seite 212). Zwar ist es mit diesen Platten und Schienen möglich, auch benachbarte Wirbel gegeneinander zu fixieren; ebenso wie bei einer Fixierung durch Knochenspäne (Operationsatlas, Seite 208/209) ist der Abstand, in dem die beiden Wirbel ruhiggestellt werden, jedoch bei diesen Konstruktionen nicht einstellbar.Furthermore, constructions are made of plates or rails known to be attached directly to the vertebrae to be fixed, for example by screws and / or metal pins, be consolidated (Operating Atlas, page 212). Although it is possible with these plates and rails, also neighboring vertebrae to fix against each other; as well as in the case of fixation with bone chips (surgical atlas, Page 208/209) is the distance at which the two vertebrae are immobilized, however not adjustable with these constructions.
Aufgabe der Erfindung ist es, einen Spondylodese-Stabilisator zu schaffen, der die Vorteile der beiden bekannten Konstruktionsprinzipien vereinigt, ohne dass die geschilderten Nachteile in Kauf genommen werden müssen. Diese Aufgabe wird mit der vorliegenden Erfindung gelöst durch an je einem der zu fixierenden Wirbel zu befestigende Laschen, die Gewindebohrungen mit gegenläufigem Umlaufsinn haben, und ferner durch Verbindungsbolzen, die durch Mittel für das Angreifen eines Werkzeugs getrennte gegensinnige Gewinde tragen. Die Gewindebohrungen tragenden Laschen werden dabei mit Vorteil durch Knochenschrauben, die durch den Wirbelbogenfuss (Pedikel) hindurch bis in den Wirbelkörper reichen, befestigt, wobei zum Ausgleich von Knochenunebenheiten Unterlagscheiben vorgesehen sein können. Durch Verdrehen des Verbindungsbolzens ist es auf einfache Weise möglich, in gewissen Grenzen jeden beliebigen Abstand zwischen den beiden zu fixierenden Wirbeln einzustellen und darüberhinaus im Laufe der Zeit Korrekturen dieses Abstandes vorzunehmen. Ein weiterer Vorteil der neuen Konstruktion besteht darin, dass die mechanische Fixierung in unmittelbarer Nähe der gegeneinander ruhigzustellenden Gelenkflächen erfolgt.The object of the invention is to create a spinal fusion stabilizer, which combines the advantages of the two well-known construction principles without the disadvantages described must be accepted. This task is done with the present invention solved by each one of the vertebrae to be fixed fastening tabs that have threaded holes with opposite directions of rotation, and furthermore by connecting bolts, which by means for engaging a tool wear separate opposing threads. The tabs bearing the threaded holes will be with the advantage of bone screws that pass through the vertebral arch foot (pedicle) extend through to the vertebral body, attached, to compensate for uneven bones Washers can be provided. By turning the connecting bolt it is possible in a simple way, within certain limits, any desired distance between the two vertebrae to be fixed and furthermore in the course to make corrections to this distance over time. Another benefit of the new Construction consists in having mechanical fixation in close proximity of the joint surfaces to be immobilized against each other.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert.In the following the invention is based on an exemplary embodiment explained in more detail.
Fig. 1 zeigt in einer Ansicht von dorsal die Fixierung zweier Wirbel mit Hilfe der neuen Stabilisatoren; Fig. 2 ist eine Aufsicht auf Fig. 1 von oben; Fig. 3 und 4 geben als Detail eine der Laschen in gleicher Darstellung wie Fig. 1 und 2 wieder. 1 shows the fixation of two vertebrae in a dorsal view with the help of the new stabilizers; Fig. 2 is a plan view Fig. 1 from above; 3 and 4 show one of the tabs in the same representation as a detail like Fig. 1 and 2 again.
Zur Fixierung der zwischen zwei benachbarten Wirbeln 1 liegenden Gelenke 2 sind an jedem Wirbel 1 beidseits ihrer Mittelebene Laschen 3' bzw. 3 " befestigt, von denen eine in einer der Darstellung der Fig. 1 und 2 entsprechenden Weise als Detail in Fig. 3 und 4 gezeigt ist.To fix the joints lying between two adjacent vertebrae 1 2 tabs 3 'or 3 "are attached to each vertebra 1 on both sides of its median plane, of which one in a manner corresponding to the representation of FIGS. 1 and 2 as Detail in Figs. 3 and 4 is shown.
Die Laschen 3 haben zum einen eine Gewindebohrung 5 (Fig. 3), die beispielsweise in Fig. 1 bei der rechten unteren und der linken oberen Lasche 3' einen Drehsinn (Rechtsgewinde) haben, der zu demjenigen (Linkgsgewinde) an der rechten oberen und der linken unteren Lasche 3 " entgegengesetzt ist. Weiterhin besitzen die Laschen 3 eine senkrecht zur Gewindebohrung 5 verlaufende Bohrung 8.The tabs 3 have on the one hand a threaded hole 5 (Fig. 3), which for example in Fig. 1 at the right lower and the left upper flap 3 ' have a direction of rotation (right-hand thread) that corresponds to the one (left-hand thread) on the right upper and lower left flap 3 "is opposite. Continue to own the tabs 3 have a bore 8 running perpendicular to the threaded bore 5.
Die Befestigung der Laschen 3 im Wirbel erfolgt durch die Bohrungen 8 hindurch mit Hilfe von relativ langen Knochenschrauben 4, die von dorsal durch die Pedikel 6 hindurch tief in die Wirbelkörper 7 hin#ein reichen. Um dabei die relativ starken Unebenheiten der Oberflächen der Pedikel 6 auszugleichen und einen festen Sitz der Lasche 3 am Wirbelknochen zu gewährleisten, ist zwischen den Laschen 3 und den Pedikeln 6 jeweils eine Unterlagsscheibe 9 (Fig. 2) vorgesehen.The fastening of the tabs 3 in the vertebra is done through the holes 8 through with the help of relatively long bone screws 4, which from the dorsal through the pedicles 6 reach deep into the vertebral bodies 7. To do the to compensate for relatively strong unevenness of the surfaces of the pedicle 6 and one To ensure a firm fit of the flap 3 on the vertebral bone is between the flaps 3 and the pedicles 6 each have a washer 9 (FIG. 2).
In die Gewindebohrungen 5 -der Laschen 3 sind Verbindungsbolzen 10 eingeschraubt, die in ihren unteren bzw. ihren oberen Hälften den Gewinden der Laschen 3' bzw. 3 " entsprechende Gewinde 11' und 11 " tragen. In der Mitte sind die gegenläufigen Gewinde 11' und 11'' durch ein als Sechskant ausgebildetes Mittelstück 12 voneinander getrennt; an dieses kann ein Schraubenschlüssel angreifen, wenn der durch die Verbindungsbolzen 10 fixierte Abstand zwischen den Wirbeln 1 eingestellt oder verändert werden soll.Connecting bolts 10 are inserted into the threaded bores 5 of the tabs 3 screwed in, the threads of the tabs in their lower or upper halves 3 'or 3 "wear corresponding threads 11' and 11". In the middle are the opposing ones Thread 11 'and 11' 'from one another by a center piece 12 designed as a hexagon separated; a wrench can attack this, if the distance between the vertebrae 1 fixed by the connecting bolts 10 is set or should be changed.
