Abstract
Description
Die Erfindung betrifft ein Zwischenwirbel-Implantat mit an benachbarten Wirbelkörpern anlegbaren Stützflächen und mit einer Verstellvorrichtung zum Ändern der relativen Lage der Stützflächen.The invention relates to an intervertebral implant adjacent vertebral bodies and supporting surfaces an adjusting device for changing the relative position of the Support surfaces.
Nach der Entfernung von Zwischenwirbelkörpern besteht die Gefahr, daß benachbarte Wirbelkörper unmittelbar aufeinan derliegen und durch diese unnatürliche Fehlstellung Schä digungen sowohl des Stützapparates als auch der umgebenden Weichteile eintreten.After the removal of intervertebral bodies, there is the Danger of neighboring vertebral bodies immediately touching one another lying there and sham by this unnatural misalignment damage to both the support apparatus and the surrounding area Soft tissues enter.
Um dies zu vermeiden, ist es bekannt, die Zwischenwirbel körper nach der Entnahme durch ein Zwischenwirbel-Implantat zu ersetzen, beispielsweise in Form eines Quaders oder ei nes Keiles. Das Einsetzen derartiger Zwischenwirbelkörper ist schwierig, daher werden häufig Zwischenwirbelkörper eingesetzt, die nicht die erforderliche Größe haben. Wenn die Zwischenwirbelkörper geringfügig kleiner gewählt wer den, ist das Implantieren leichter, jedoch kann die Stütz funktion nicht vollkommen erfüllt werden.To avoid this, it is known the intervertebral vertebrae body after removal through an intervertebral implant to replace, for example in the form of a cuboid or egg a wedge. The insertion of such intervertebral bodies is difficult, therefore intervertebral bodies are common used that are not the required size. If the intervertebral bodies are chosen slightly smaller The implantation is easier, but the support can function cannot be completely fulfilled.
Es ist bereits bekannt, Zwischenwirbel-Implantate zu ver wenden, deren Außenstruktur nach dem Einsetzen durch eine geeignete Verstellvorrichtung verändert werden kann. So be schreibt beispielsweise die WO 92/14423 ein Zwischenwir bel-Implantat mit einem Zuganker, bei dem zwischen benach barten Stirnflächen des Implantates verschwenkbar angeord nete Seitenwandabschnitte durch einen Zuganker mehr oder weniger nach außen verschwenkt werden können. Zwar wird es dadurch möglich, die Größe des Zwischenwirbel-Implantates nach der Implantation zu verändern, der Aufbau eines sol chen Zwischenwirbel-Implantates ist jedoch außerordentlich kompliziert und läßt außerdem keine flächige Anlage der Stützfläche am Wirbelkörper zu, da die Stützflächen klein räumig verschwenkt werden müssen.It is already known to ver vertebral implants turn, the external structure after insertion by a suitable adjustment device can be changed. So be For example, WO 92/14423 writes an intermediate wire bel implant with a tie rod, in which between neighboring beard end faces of the implant pivotally arranged nete side wall sections by a tie rod more or can be pivoted less to the outside. It will this enables the size of the intervertebral implant after implantation change, building a sol Chen intervertebral implant is exceptional complicated and also leaves no area of the Support surface on the vertebral body too, since the support surfaces are small must be pivoted spatially.
Aus der EP 260044 B1 ist ein zweiteiliges Zwischenwirbel- Implantat bekannt, bei dem zwischen zwei Teilen Spreizkör per angeordnet sind, die ebenfalls durch Zuganker und axia le Verschiebung die Spreizflächen voneinander entfernen können. Auch hier ist der Aufbau des Implantates relativ kompliziert, da eine größere Anzahl von Teilen notwendig ist. Außerdem ergibt sich hier nur eine linienförmige Anla ge, da die Außenfläche dieses Implantats einen kreisförmi gen Querschnitt aufweist.EP 260044 B1 describes a two-part intervertebral Known implant, in which between two parts spreader are arranged by, also by tie rods and axia le shifting the spreading surfaces away from each other can. Here too, the structure of the implant is relative complicated because a larger number of parts is necessary is. In addition, there is only a linear layout here ge, since the outer surface of this implant has a circular has a cross-section.
Einen ähnlichen Aufbau eines Zwischenwirbel-Implantates be schreibt die WO 90/00037. Keilförmige Spreizelemente zwi schen zwei Stützflächen werden durch einen Zuganker mehr oder weniger einander angenähert und drücken dabei die Stützflächen auseinander. Auch hier ist eine große Anzahl von Einzelteilen notwendig, die zu dem Zwischenwirbel- Implantat zusammengebaut werden müssen, so daß die Gefahr von Funktionsstörungen nicht auszuschließen ist.A similar structure of an intervertebral implant writes WO 90/00037. Wedge-shaped expansion elements between Two support surfaces are increased by a tie rod or less approached each other and press the Support surfaces apart. Again, there is a large number of individual parts necessary for the intervertebral Implant must be assembled so that the danger malfunctions cannot be excluded.
Es ist Aufgabe der Erfindung, ein gattungsgemäßes Zwischen wirbel-Implantat so zu verbessern, daß ein besonders einfa cher und robuster Aufbau und eine störungsfreie Funktion gewährleistet sind.It is an object of the invention to provide a generic intermediate to improve vertebral implant so that a particularly simple Safe and robust construction and trouble-free function are guaranteed.
Diese Aufgabe wird bei einem Zwischenwirbel-Implantat der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Stützflächen durch die Außenseiten der im wesentli chen parallel zueinander verlaufenden Schenkel eines U-för migen Stützkörpers gebildet werden, daß in einem die Schen kel einstückig miteinander verbindenden Steg des Stützkör pers eine Gewindebohrung angeordnet ist und daß in diese eine Schraube eingeschraubt ist, die an den zum freien Ende der Schenkel hin sich aneinander annähernden Innenflächen der Schenkel anliegt und die Schenkel dadurch entsprechend ihrer Einschraubtiefe mehr oder weniger nach außen aufbiegt.This task is performed with an intervertebral implant solved in accordance with the invention, that the support surfaces through the outside of the in essence Chen parallel legs of a U-för Migen support body that are formed in one of the Schen kel integrally connecting web of the support body pers a threaded hole is arranged and that in this a screw is screwed in to the free end the thighs approaching inner surfaces the leg rests and the leg accordingly its screwing depth more or less bends outwards.
Es wird also im Gegensatz zu allen anderen bekannten Zwi schenwirbel-Implantaten mit Verstellmöglichkeit ein ein stückiger Stützkörper verwandt, in den als Verstellvorrich tung lediglich eine Schraube eingeschraubt ist. Diese Schraube liegt unmittelbar an den Innenflächen der Schenkel des Stützkörpers an und drückt diese je nach ihrer Ein schraubtiefe mehr oder weniger auseinander. Dieses Zwi schenwirbel-Implantat ist äußerst einfach aufgebaut, da es lediglich aus zwei Teilen besteht, und es ermöglicht trotz dem sehr feinfühlig eine Verstellung der Stützflächen al lein durch Verbiegung der Schenkel nach außen. Diese ge ringfügige Verschwenkung der Stützflächen ist auch aus ana tomischer Sicht günstig, da auf diese Weise eine geringfü gige Lordosierung der Wirbelkörper erreicht werden kann, auch diese Größe läßt sich durch die Schraube besonders einfach justieren. Dabei besteht noch die Möglichkeit, den Betrag der Aufspreizung zu variieren, indem unterschiedli che Schrauben in den Stützkörper eingeschraubt werden, ins besondere läßt sich dadurch auch der absolute Betrag der Verstellung einstellen, der pro Einschraubtiefe der Schrau be auftritt.So it becomes in contrast to all other known Zwi vertebrae implants with an adjustment option lumpy support body related, in the as adjusting device only one screw is screwed in. These The screw lies directly on the inner surfaces of the legs of the support body and presses them depending on their on screwing depth more or less apart. This two vertebra implant is extremely simple because it is consists of only two parts, and it allows despite the very sensitive adjustment of the support surfaces al lein by bending the legs outwards. This ge ring-shaped pivoting of the support surfaces is also made of ana tomic view favorable because in this way a slight common lordosis of the vertebral bodies can be achieved this size can also be adjusted with the screw just adjust. There is still the option of Amount of spread to vary by differing screws are screwed into the support body the absolute amount of the Set the adjustment per screw depth of the screw be occurs.
Ein besonderer Vorteil der Aufbiegung der Schenkel ist auch darin zu sehen, daß dadurch ein Gleiten des Implantates in dorsaler Richtung mit Sicherheit verhindert wird, da der Wirbelzwischenraum in dieser Richtung sich verengt und das Implantat aufgrund seiner Keilform an einer weiteren Ver schiebung in dorsaler Richtung gehindert wird.A special advantage of bending the legs is also to be seen in the fact that this causes the implant to slide in dorsal direction is prevented with certainty since the Vertebral space in this direction narrows and that Implant due to its wedge shape on another ver movement in the dorsal direction is prevented.
Günstig ist es, wenn die Schraube sich in ihrem Spitzenbe reich konisch verjüngt, auf diese Weise kann eine größere Anlagefläche der Schraube an der Innenfläche erreicht wer den und damit auch eine geringere Reibung zwischen Schraube und Innenfläche beim Einschrauben. Dabei ist es weiterhin vorteilhaft, wenn die Schraube in ihrem Spitzenbereich ge windefrei ausgebildet ist.It is favorable if the screw is in its tip position richly tapered, this way it can be larger Contact surface of the screw on the inner surface is reached that and therefore less friction between the screw and inner surface when screwing in. It is still there advantageous if the screw ge in its tip area is designed to be windless.
Vorzugsweise liegt die Schraube im vorderen Drittel der Schenkel an deren Innenfläche an, so daß die Schenkel dann einmal durch den Steg am hinteren Ende und dann durch die Schraube im Bereich des vorderen Endes unterstützt werden. The screw is preferably in the front third of the Legs on their inner surface so that the legs then once through the web at the rear end and then through the Screw in the area of the front end are supported.
Günstig ist es, wenn sich die Dicke der Schenkel von dem die Schenkel verbindenden Steg zum freien Ende hin vergrößert. Durch den Grad der Dickenänderung läßt sich im übri gen auch der Biegeverlauf des Schenkels in geringem Umfange beeinflussen, so daß gegebenenfalls der Biegeverlauf des Schenkels an die Form der Wirbelkörper angepaßt werden kann.It is favorable if the thickness of the legs is different the web connecting the legs is enlarged towards the free end. By the degree of the change in thickness can otherwise also the bending curve of the leg to a small extent influence, so that the bending curve of the Leg can be adapted to the shape of the vertebral body.
Die Innenflächen der unverbogenen Schenkel können eben aus gebildet sein.The inner surfaces of the unbent legs can be made of be educated.
Günstig ist es, wenn zumindest die Stützflächen struktu riert sind. Dadurch erhält man eine Fixierung des Stützkör pers zwischen den Wirbelkörpern und außerdem kann diese Strukturierung dazu beitragen, daß das Knochenmaterial in den Stützkörper einwächst.It is favorable if at least the support surfaces are structured are. This results in a fixation of the support body pers between the vertebral bodies and also this can Structuring help keep the bone material in ingrows the support body.
Beispielsweise kann die Strukturierung durch von den Stütz flächen abstehende Dorne oder Spitzen gebildet werden oder durch in die Stützflächen eingearbeitete Vertiefungen. Die se können beispielsweise als Bohrungen oder Schlitze aus gebildet sein.For example, the structuring can be carried out by the support protruding spikes or tips are formed or through recesses worked into the supporting surfaces. The For example, they can be bores or slots be educated.
Besonders günstig ist es, wenn die Strukturierung durch ei ne poröse Beschichtung der Stützflächen gebildet wird, die gleichzeitig eine besonders knochenfreundliche Oberfläche sein kann, so daß das Knochenmaterial in diese Oberfläche einwächst.It is particularly favorable if the structuring by egg ne porous coating of the support surfaces is formed, the at the same time a particularly bone-friendly surface can be so that the bone material in this surface ingrows.
Vorzugsweise ist der Stützkörper in unverformtem Zustand quaderförmig ausgebildet.The support body is preferably in the undeformed state cuboid.
Bei einer besonderen Ausführungsform kann vorgesehen sein, daß der Stützkörper an seiner Stegseite von oben gesehen einseitig durch eine Abschrägung oder durch einen Bogen verkürzt ist. Dadurch wird es möglich, insgesamt länger ausgebildete Stützkörper in dem Raum zwischen zwei Wirbeln unterzubringen, ohne daß die Stützkörper über den Quer schnitt der grob gesprochen kreisförmigen Wirbelkörper mit einer Ecke vorsteht. Die Vergrößerung der Stützfläche führt zu geringeren Flächenpressungen und damit zu einer geringe ren Gefahr, daß der Stützkörper in das Knochenmaterial ein sinkt.In a special embodiment it can be provided that the support body is seen from above on its web side one-sided by a bevel or by an arch is shortened. This makes it possible to stay longer overall trained support body in the space between two vertebrae accommodate without the support body over the cross the roughly circular vertebral body cut along protrudes from a corner. The enlargement of the support surface leads to lower surface pressures and thus to a low one ren danger that the support body into the bone material sinks.
Die nachfolgende Beschreibung bevorzugter Ausführungsformen der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:The following description of preferred embodiments the invention serves in connection with the drawing of the detailed explanation. Show it:

Das Zwischenwirbel-Implantat der vorliegenden Erfindung um faßt einen im wesentlichen U-förmigen Stützkörper 1 mit ei nem quaderförmigen Querschnitt. In diesem Stützkörper 1 ist ein Innenraum 2 mit trapezförmigem Querschnitt ausgenommen, so daß der Stützkörper 1 zwei im wesentlichen parallel zu einander verlaufende Schenkel 3 und 4 und einen im wesent lichen senkrecht dazu verlaufenden, die beiden Schenkel 3 und 4 miteinander verbindenden Steg 5 aufweist. Durch den trapezförmigen Querschnitt des Innenraumes 2 sind die ebe nen Innenflächen 6, 7 der Schenkel 3, 4 derart gegeneinan der geneigt, daß sie sich zu den freien Enden der Schenkel 3, 4 hin einander annähern. Außerdem nimmt die Dicke der Schenkel 3, 4 vom Steg 5 zu den freien Enden der Schenkel 3, 4 hin zu.The intervertebral implant of the present invention comprises a substantially U-shaped support body 1 with a cuboid cross-section. In this support body 1 , an interior 2 with a trapezoidal cross-section is excluded, so that the support body 1 has two legs 3 and 4 which run essentially parallel to one another and an essentially perpendicular to it, the two legs 3 and 4 connecting web 5 . Due to the trapezoidal cross section of the interior 2 , the inner surfaces 6 , 7 of the legs 3 , 4 are inclined towards one another in such a way that they approach each other towards the free ends of the legs 3 , 4 . In addition, the thickness of the legs 3 , 4 increases from the web 5 to the free ends of the legs 3 , 4 .
Im Steg 5 befindet sich eine durchgehende Gewindebohrung 8, in diese ist eine Schraube 9 eingeschraubt, die an ihrem freien Ende eine gewindefreie Anlagefläche 10 in Form eines Kegelstumpfes aufweist. Diese liegt im vorderen Drittel an den beiden Innenflächen 6, 7 an und weitet den Innenraum 2 je nach Einschraubtiefe mehr oder weniger auf, das heißt die Schenkel 3, 4 werden unter dem Einfluß der Schraube 9 elastisch nach außen gebogen. Das Einschrauben der Schraube 9 kann dabei beispielsweise mit einem Mehrkantschlüssel 11 erfolgen, der in eine in der Zeichnung nicht dargestellte Mehrkantöffnung der Schraube eintaucht.In the web 5 there is a continuous threaded bore 8 , into which a screw 9 is screwed, which has a thread-free contact surface 10 in the form of a truncated cone at its free end. This lies in the front third on the two inner surfaces 6 , 7 and widens the interior 2 more or less depending on the screwing depth, that is, the legs 3 , 4 are bent elastically outwards under the influence of the screw 9 . The screw 9 can be screwed in, for example, with a polygonal wrench 11 which plunges into a polygonal opening of the screw, not shown in the drawing.
Die Außenflächen der Schenkel 3, 4 bilden Stützflächen 12, die bei unverformtem Stützkörper 1 im wesentlichen eben ausgebildet sind und die sich beim Einschrauben der Schrau be 9 in den Stützkörper 1 geringfügig nach außen wölben. Diese Stützflächen 12, 13 können in aus der Zeichnung nicht ersichtlicher Weise mit einer Struktur versehen sein, bei spielsweise können dort Spitzen oder Dorne aufgesetzt sein oder es können Löcher in die Stützfläche 12, 13 eingebohrt sein. Diese Strukturierung verbessert den Kontakt zu an der Stützfläche 12 anliegendem Knochengewebe. Bei einer anderen Ausführungsform sind die Stützflächen 12, 13 und eventuell der gesamte Stützkörper 1 mit einer rauhen Oberfläche be schichtet, beispielsweise mit einer mikroporösen Oberflä che, so daß einerseits die Rauhigkeit erhöht und anderer seits der Eingriff mit benachbartem Knochengewebe verbes sert werden können.The outer surfaces of the legs 3 , 4 form support surfaces 12 , which are essentially flat when the support body 1 is undeformed and which, when the screw is screwed in 9, bulge slightly outwards into the support body 1 . These support surfaces 12 , 13 can be provided with a structure in a manner not shown in the drawing, for example tips or mandrels can be placed there or holes can be drilled into the support surface 12 , 13 . This structuring improves the contact with bone tissue lying against the support surface 12 . In another embodiment, the support surfaces 12 , 13 and possibly the entire support body 1 are coated with a rough surface, for example with a microporous surface, so that on the one hand the roughness is increased and on the other hand the engagement with adjacent bone tissue can be improved.
Der Stützkörper 1 und die Schraube 3 bestehen aus körper verträglichen Metallen, Metall-Legierungen oder Kunststof fen, beispielsweise aus Titan.The support body 1 and the screw 3 are made of body-compatible metals, metal alloys or plastics, for example titanium.
Wie sich aus den Darstellungen der Fig. 1 und 2 ergibt, wird der Stützkörper 1 derart zwischen zwei benachbarte Wirbelkörper 14 eingelegt, daß die Stützflächen 12 und 13 flächig an den benachbarten Wirbelkörpern zur Anlage kom men. Dabei werden zwischen jeweils zwei Wirbelkörper die Stützkörper 1 immer paarig eingelegt, die Stege 5 sind da bei in dorsaler Richtung orientiert, die freien Enden der Schenkel 3 und 4 in ventraler. Auf diese Weise ist es mög lich, die Schraube 9 vom Rücken her in den Stützkörper 1 mehr oder weniger tief einzuschrauben, um dadurch ein Auf biegen der Schenkel 3, 4 zu erreichen und damit eine Verän derung des Abstandes und eventuell auch in geringem Umfange der gegenseitigen Orientierung der benachbarten Wirbelkör per 14. Bei einfachstem Aufbau des Stützkörpers 1 können damit die notwendigen Stützfunktionen durch diesen übernom men werden. Es ist besonders vorteilhaft, daß das Zwischen wirbel-Implantat in einfacher Weise auch wieder entfernt werden kann. Es genügt nämlich dazu, die Schraube 9 soweit auszuschrauben, daß die Schenkel wieder in die unverformte Stellung gelangen, dann können die Stützkörper 1 in einfa cher Weise entnommen und gegebenenfalls ersetzt werden. As is clear from the illustrations of FIGS. 1 and 2 shows the supporting body 1 is so inserted between two adjacent vertebral bodies 14, that the support surfaces 12 and 13 men kom surface of the adjacent vertebral bodies to the plant. The support bodies 1 are always inserted in pairs between two vertebral bodies, the webs 5 are oriented in the dorsal direction, the free ends of the legs 3 and 4 in the ventral direction. In this way, it is possible to screw the screw 9 from the back into the support body 1 more or less deeply, thereby bending the legs 3 , 4 to achieve and thus a change in the distance and possibly to a small extent mutual orientation of the neighboring vertebrae by 14 . With the simplest structure of the support body 1 , the necessary support functions can be taken over by this men. It is particularly advantageous that the intervertebral implant can also be removed in a simple manner. It is sufficient to unscrew the screw 9 so far that the legs return to the undeformed position, then the support body 1 can be removed in a simple manner and replaced if necessary.
Während der bisher beschriebene Stützkörper quaderförmige Außenkonturen aufweist, ist es möglich, hiervon geringfügig abzuweichen. Beispielsweise kann der quaderförmige Stütz körper 1 im Bereich des Steges 5 einen von oben her gesehen an einer Ecke abgeschrägten oder durch einen Bogen verkürz ten Querschnitt aufweisen, wie dies durch die gestrichelte Grenzlinie 15 in Fig. 1 dargestellt ist. Ein in dieser Weise abgewandelte Stützkörper 1 ist an die Außenkontur des Wirbelkörpers 14 angepaßt und kann daher entsprechend län ger ausgebildet werden, ohne über die Kontur des Wirbelkör pers 14 hervorzustehen. Da die beschriebenen Zwischenwir bel-Implantate zu einer Horizontalebene vollständig symme trisch aufgebaut sind, genügt es dabei, den in dieser Weise seitlich abgeschrägten oder mit einer bogenförmigen Kontur 15 versehenen Stützkörper 1 in unterschiedlicher Orientie rung einzusetzen, so daß auf der einen Seite die linke Ecke und auf der anderen Seite die rechte Ecke des Stützkörpers kürzer ausgebildet ist, wie dies in Fig. 1 dargestellt ist.While the previously described support body has cuboidal outer contours, it is possible to deviate slightly from it. For example, the parallelepiped-shaped support body 1 in the region of the web 5 can have a cross section which is chamfered at a corner or shortened by an arc, as shown by the dashed boundary line 15 in FIG. 1. A modified in this way support body 1 is adapted to the outer contour of the vertebral body 14 and can therefore be formed accordingly longer without protruding pers 14 on the contour of the vertebral body. Since the described intervertebral implants are constructed completely symmetrically to a horizontal plane, it suffices to use the side beveled in this way or provided with an arcuate contour 15 support body 1 in different orienta tion, so that the left corner on one side and on the other hand, the right corner of the support body is shorter, as shown in Fig. 1.
