Das Hauptpaterit betrifft ein hülsenförmiges, in Anpassung an den Knochenkanal gebogenes Stützelement für Röhrenknochenfrakturen, insbesondere für Untertchenkelfrakturcn, das in eine an der Frontseite des Knochens befindliche öffnung einschiebbar und bei dem ein Spreizkörper über eine an ihm ansetzbare Gewindestainge und einer sich an einem Ende des Slützelementeü abstützenden Kopfhülse in das andere Ende fcu dessen Verankerung in dem einen Knochenbruchfctück einziehbar ist, wobei auf ein nach der Verankerung die Kopfhülse überragendes Stück der Gewinde-Stange zum Zusammenziehen der Knochenbruchstücke eine weitere Kopfmuttcr aufschraubbar ist, und hai zum Gegenstand, daß sich die Kopfmutter auf einer Scheibe abstützt, die nahezu rechtwinklig zur Längsrichtung de» Stützelementes in .J!e Öffnung im Knochen ragt, und an der wenigstens zwei Laschen angeordnet sind, die an der Öffnungskante am Knochen so umgebördelt sind, daß sie an der Frontseite des Knochens entgegengesetzt gerichtet anliegen. The main paterite relates to a sleeve-shaped support element for tubular bone fractures, in particular for lower leg fractures, which is bent to match the bone canal, which can be inserted into an opening on the front side of the bone and in which an expansion body has a threaded rod attachable to it and one at one end of the support element The supporting head sleeve can be drawn into the other end for its anchoring in the one broken bone piece, whereby a further head nut can be screwed onto a piece of the threaded rod protruding beyond the head sleeve after anchoring to pull the bone fragments together, and the object is that the head nut is on a disk which is almost at right angles to the longitudinal direction of the »support element in. J ! E opening in the bone protrudes, and on which at least two tabs are arranged, which are flanged at the opening edge on the bone so that they rest in opposite directions on the front side of the bone.
Durch diese Lösung ist nunmehr nach der Verankerung und unabhängig von ihr ein Zusammenziehen der KnoehenfiMigmente insbesondere bei Umerwhenkelfn ituren 5-ch, bei denen das SiOi/e emcnt von der nahe» parallel zur Längsrichtung; des Unterschenkels Erlaufenden Frontseite des Knochens her in den Kriochcnkanal des Unterschenkels eingeschoben wird. Allerdings ist /um Einsetzen der Scheibe eine sehr große Bohrung im Unterschenkelknochen erforderlich. Ferner können beim Zusammengehen der KnochenTragmcnte unter Umständen so Croße Kräfte auf die Sehe.- As a result of this solution, after the anchoring and independently of it, there is now a contraction of the bone pigments, particularly in the case of reversed structures, in which the SiOi / e emcnts from the near »parallel to the longitudinal direction; of the lower leg running front side of the bone is pushed into the cranial canal of the lower leg. However, a very large hole in the lower leg bone is required / in order to insert the disc. Furthermore, in the merger of the KnochenTragmcnte as C arge forces may be able to Sehe.-

' Vor dem Einführen des hülsenförmigen Stützelementes in den Röhrenknochen wird zunächst die Gewindestan<*e als Nagel zur Vorfixierung der Knochenfragnicnte verwendet. Hierzu wird der Unterschenkel lapp unterhalb der Kniescheibe angebohrt, um einen Durchgang /um Knochenkanal zu schaffen. Durch diese C ung wird nun die entsprechend dem Verlauf des Kno-nenkanals vorgebogene Gewindestange in den mit Knochenmark ausgefüllten Knochenkanal geschoben Der gegenüber dem Knochenkanal geringe Außendurchmesser der Gewindestange erlaubt es. diese trotz einer eventuellen Versetzung der Knochenfragmente in der Bruchzone durch das vordere Knochenbruchstück hindurch in das hintere Knochenbruch stück einzuschieben. Dabei weiden die Knochenfragmente in Längsrichtung ausgerichtet und in dieser vorfixierten Stellung gehalten. Über diese eingesetzte Gewindestange, die an ihrem unteren Ende einen Ansatz aufweist, wird nun das gebogene, hülsenförmige Stützelemeni so weil eingeschoben, bis der am vorderen Ende des Stützelementes gehaltene Spreizkörper auf dem Ansatz an der Gewindestange aufliegt. Durch Drehen der in einer Erweiterung im oberen Teil des Stützelementes geführten, auf die Gewindestange aufge-'Before inserting the sleeve-shaped support element The threaded rod is first inserted into the long bones as a nail for pre-fixing the bone fragments used. For this purpose, the lower leg is drilled below the kneecap to make a Passage / to create a bone canal. Through this C ung the according to the course of the Bone canal pre-bent threaded rod into the Bone canal filled with bone marrow pushed The small one compared to the bone canal The outer diameter of the threaded rod allows it. this despite a possible dislocation of the bone fragments in the fracture zone through the anterior bone fragment into the posterior bone fracture insert piece. The bone fragments graze in the longitudinal direction and are pre-fixed in this Position held. About this inserted threaded rod, which has an approach at its lower end has, the curved, sleeve-shaped support element is now so because pushed in until the spreading body held at the front end of the support element on the Approach rests on the threaded rod. By turning the in an extension in the upper part of the support element guided on the threaded rod
schraubten Kopfhülse wird die Gcwindestange unter Mitnahme des Spreizkörpers in den Spreizteil eingezogen und damit das Stützelement in dem einen Knochcnbruchstück verankert. Die Gewindlestange bewegt sich dabei nur in Achsrichtung des Stützciementes, da durch die Biegung des Stützelementc«. ein Verdrehen der Gewindestange in der Bohrung des Stützelcmentes nicht möglich ist. Durch die Krümmung liegt außerdem das Stützelement über einen größeren Bereich an der Innenwand des Knochcnkanals an. Der gebrochene Röhrenknochen ist somit seitlich fixiert, und die Knochenfragfflente können sich an der Bruchstelle nicht mehr gegeneinander verschieben. When the head sleeve is screwed, the threaded rod is drawn into the expansion part with the expansion body being carried along and the support element is anchored in the one bone fragment. The threaded rod moves only in the axial direction of the support element, since it is caused by the bending of the support element. it is not possible to turn the threaded rod in the bore of the support element. As a result of the curvature, the support element also rests against the inner wall of the bone canal over a larger area. The broken long bone is thus fixed laterally, and the bone fragments can no longer move against each other at the fracture site.
Die Oewindestange ist so lang, daß sie nach der Verankerung des Stützelementes ein Stück über die Kopf-The threaded rod is so long that after the anchoring of the support element it is a little over the head hülst· hinausragt. Nun wird über das dem Einführende entgegengesetzte Ende des Stüizelementes eine Hülse geschoben, die mit einer an ihr angeordneten hakenartigen Lasche in eine Öffnungskante de» Knochens ein-hülst protrudes. A sleeve is now placed over the end of the support element opposite the insertion end pushed into an opening edge of the »bone with a hook-like tab arranged on it.

hüngbar ist. Die hakenartige Lascht; muß beim Zusammenziehen der Knochenfrngmente die in Längsrichtung des .Stützelementes wirkenden Axialkräfte aufnehmen, während das durch die einseitige Abstützung der Hülse erzeugte Drehmoment durch die Anlage der Hülse an der Innenwand des Knochenkanals aufgenommen wird. Nach der Größe der zu erwartenden Orehmomentbelastung richtet sich auch die Lange der Hülse. Um die Flächenpressung an der Innenwand des Knochenkanals durch die Hülse möglichst klein zu hailen. wird bei großem Drehmoment eine lange, bei kleinem Drehmoment eine kurze Hülse verwendet. Da nur noch eine an der Hülse angeordnete Lasche zur Abstützung am Knochen in eine Öffnungskante eingehängt werden muß, ist der Platzbedarf dieser Hülse gegenuber der Scheibe nach dem Hauptpatent, bei der eine weitere Lasche an der oberen Öffnungskante des Knochens eingehakt werden muß, bedeutend geringer. Ferner kann die Hülse weit größere Belastungen aufnehmen, da durch die günstigeren Hebelverhältnisse ao und durch das Anliegen der Hülse an der Innenwand des Knochenkanals eine bessere Drehmomentaulnuhme als beim Hauptpatent erreicht wird. Die Hülse im bereits durch Einhängen der hakenar'igen Lasche an der Öffnungskante des Knochens gegen Verdrehen ge- as genüber dem Unterschenkelknochen gesichert. Es ist nur noch notwendig, auch das Stützelement gegenüber der Hülse und damit gegenüber dem Unterschenkel gegen Verdrehen zu sichern.is hangable. The hook-like lashing; must when contracting the bone fragments absorb the axial forces acting in the longitudinal direction of the support element, while the torque generated by the one-sided support of the sleeve through the plant of Sleeve is received on the inner wall of the bone canal. According to the size of the expected The torque load also depends on the length of the sleeve. To reduce the surface pressure on the inner wall of the To hail the bone canal through the sleeve as small as possible. a long sleeve is used for high torque and a short sleeve for low torque. Because only another tab arranged on the sleeve for support on the bone is hooked into an opening edge must be, is the space required for this sleeve the disc according to the main patent, in which another tab on the upper edge of the opening of the Must be hooked into the bone, significantly less. Furthermore, the sleeve can absorb far greater loads, because of the more favorable lever ratios ao and because the sleeve rests against the inner wall of the bone canal a better torque tolerance is achieved than in the main patent. The sleeve in the Already by hanging the hook-like tab on the opening edge of the bone against twisting secured against the lower leg bone. It is only necessary to also have the support element opposite to secure the sleeve and thus against the lower leg against twisting.
Bei einem Stützelement, das an seinem dem Einführende entgegengesetzten Ende Drehsicherungsrippen aufweist, kann das in vorteilhafter Ergänzung der Erfindung dadurch erreicht werden, daß die Hüiae mit Schützen versehen ist, die vom vorderen Ende her in Längsrichtung der Hülse verlaufen und in denen die Drehsicherungsrippen des Stützelementes geführt sind. Das Stützelement ist dadurch gegenüber der Hülse gegen Verdrehen gesichert, die ihrerseits gegenüber dem Knochen durch die an der Öffnungskante eingehängte Lasche gegen Verdrehen gesichert ist.In the case of a support element that has anti-rotation ribs at its end opposite the insertion end has, this can be achieved in an advantageous addition to the invention that the Hüiae with Protect is provided, which run from the front end in the longitudinal direction of the sleeve and in which the Anti-rotation ribs of the support element are performed. The support element is thus against the sleeve Twisting secured, which in turn opposite the bone by the hooked on the opening edge Tab is secured against twisting.
Nacn einer weiteren Ausgestaltung der Erfindung kann in das hintere Ende der Hülse eine weitere Hülse einschiebbar sein, die einen die Stirnseite der Hülse überdeckenden Bund aufweist. Diese Hülse mit Bund dient zur Vergrößerung der Auflagefläche für die Kopfmutter, damit die Flächenpressung zwischen Kopf und Kopfmutter und der Stirnseite der Hüls? nicht allzu groß wird.According to a further embodiment of the invention, a further sleeve can be inserted into the rear end of the sleeve be insertable, which has a collar covering the end face of the sleeve. This sleeve with a collar serves to enlarge the contact surface for the head nut so that the surface pressure between the head and head nut and the face of the sleeve? doesn't get too big.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kann die hakenartige Lasche an der weiteren Hülse angeordnet sein. Diese Maßnahme hat den Vorteil, daß die längere, über das hintere Ende des. Stützelementes schiebbare Hülse aus einem Rohr gefertigt werden kann. Da nämlich d»s erfindungsgemäße Stützelement vorwiegend aus V2a bzw. aus V4a hergestellt wird, ist es fertigungstechnisch einfacher und billiger, die hakenartige Lasche un die kürzere, zur Verbesserung der Auflagefläche mit einem Bund versehene Hülse anzuordnen.According to a further advantageous embodiment of the invention, the hook-like tab can be arranged on the further sleeve. This measure has the advantage that the longer sleeve, which can be pushed over the rear end of the support element, can be made from a tube. Since the support element according to the invention is mainly made from V2a or from V4a, it is simpler and cheaper in terms of production technology to arrange the hook-like tab and the shorter sleeve provided with a collar to improve the support surface.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing is an embodiment of the invention shown.
Das in der Figur dargestellte hülsenförmige Stü'-zelernent 1 ist über die zur Vorfixierung der Knodienfragrnente 12 verwendbare Gewindestange 5 übergesehoben. Zum Verankern des Stützelementes 1 wird eine Kopfhülse 4 auf das aus dem Stützelement 1 herausragende Ende der Gewindestange 5 aufgeschraubt Beim Einziehen der Gewindestange 5, die sich dabei nur in Achsrichtung bewegt, stützt sich die Kopfhülse 4 an der Stirnfläche des Stützelementes 1 ab. Die Gewindestange 5 ist dabei so bemessen, daß sie nach der Verankerung des Stützelementes 1 die Kopfhülse 4 um ein Stück überragt. Über das dem Einführende entgegengesetzte Ende des Stützelementes I wird nun die Hülse 60 übergeschoben, bis die an ihr bzw. an der weiteren Hülse 61 angeordnete hat. nartige Lasche 62 an der Öffnungskante 54 des Knocher.i eingehängt ist. Auf das die Kopfhüise 4 überragende Stück der Gewindestange 5 wird nun zum Zusammenziehen der Knochenbruchstücke 12 eine Kopfmutter 50 aufgeschraubt, die sich dabei mit ihrem Kopf 51 an der Stirnseite der Hülse 60 oder an dem die Stirnseite der Hülse 60 überdeckenden Bund 63 der weiteren Hülse 61 abstützt, die in den hinteren Teil der in der Offnuntjskante 54 des Knochens eingehängten Hülse 60 einschiebbar ist.The figure shown in the sleeve-shaped Stü'-zelernent 1 is sailed over lifted over the r for prefixing the Knodienf agrnente 12 suitable threaded rod. 5 To anchor the support element 1, a head sleeve 4 is screwed onto the end of the threaded rod 5 protruding from the support element 1. The threaded rod 5 is dimensioned so that after the anchoring of the support element 1 it projects beyond the head sleeve 4 by a certain amount. The sleeve 60 is now pushed over the end of the support element I opposite the insertion end until the one arranged on it or on the further sleeve 61 has reached. n-like tab 62 is hung on the opening edge 54 of the Knocher.i. A head nut 50 is now screwed onto the piece of the threaded rod 5 protruding beyond the head cover 4 in order to pull the bone fragments 12 together, with its head 51 on the end face of the sleeve 60 or on the collar 63 of the further sleeve 61 that covers the end face of the sleeve 60 supported, which can be pushed into the rear part of the sleeve 60 suspended in the opening edge 54 of the bone.
Zur Sicherung der Hülse 60 gegen Verdrehen gegenüber dem Stützelement 1 weist diese vom vorderen Ende her in Längsrichtung der Hülse 60 verlaufende Schlitze 64 auf, in denen die Drehsicherungsrippen 65 des Stützciementes 1 geführt sind. Nach beendeter Montage werden die beiden Knochenbruchstücke 12 durch die auf den Gewindeansa:z 33 der Gewindestange 5 aufgeschraubten Kopfmutter 50 /usammengehalten und zusammengepreßt, damit sich an der Bruchfläche Kallus bilden kann. Das Stützelement 1 wird so tief in den Knochenkanal eingeschoben und dort verankert, daß nach der Montage weder die Kopfmutter 50 noch die Gewindestange 5 die Frontseite des Unterschenkelknochens — zur Vermeidung von Druckstellen — überragen.To secure the sleeve 60 against twisting with respect to the support element 1, it faces from the front At the end of the longitudinal direction of the sleeve 60 there are slots 64 in which the anti-rotation ribs 65 of the Stützciementes 1 are performed. When the assembly is complete, the two bone fragments 12 held together by the head nut 50 / us screwed onto the threaded ansa: z 33 of the threaded rod 5 and compressed to allow callus to form on the fracture surface. The support element 1 is so deep inserted into the bone canal and anchored there that after assembly neither the head nut 50 nor the threaded rod 5 the front of the lower leg bone - to avoid pressure points - tower above.
Um nach der Heilung des Bruches das Stützelement I wieder entfernen zu können, ist in der Bohrung am hinleren Teil des Stützciementes 1 ein Innengewinde 66 vorgesehen, in das ein Schraubenbolzen bzw. eine Ausziehvorrichtung ansetzbar ist.After the fracture has healed, the support element I can be removed again, there is an internal thread in the bore on the rear part of the support element 1 66 is provided, in which a screw bolt or an extractor can be attached.
