Abstract

The invention relates to an implant for the flexible, extension-resistant connection of two bone or joint fragments. There are provided two anchorage parts each one of which is fastened on the bone or joint fragment and each of which is articulated to the other. The underlying object of the invention is to offer an extension-resistant connection of the anchorage parts which has almost unlimited fatigue resistance, does not break with bending stress and does not have only extremely limited rotational mobility due to rigid parts. The achievement of the object is characterized in that the connection is formed by at least one cable.

Description

Die Erfindung betrifft ein Implantat für die biegeweiche, zugfeste Verbindung zweier Knochen- bzw. Gelenkteile, wobei zwei Ankerteile vorgesehen sind, von denen jeweils eines am Knochen- bzw. Gelenkteil befestigt ist und beide Ankerteile miteinander gelenkig verbunden sind.The invention relates to an implant for the flexible, tensile connection of two bone or joint parts, whereby Two anchor parts are provided, one of which is each on Bone or joint part is attached and both anchor parts are hinged together.

Am Beispiel des Schultereckgelenkes kann diese Problematik anschaulich erläutert werden. Es bildet die Verbindungsstel­ le zwischen dem Schlüsselbein und einem kleineren weiter außen liegenden Knochen. Ober- und unterhalb des Knochenkon­ taktes werden die beiden sich berührenden Knochen durch Bänder zusammengehalten. Zerreißen diese, können sich die Knochen voneinander entfernen. Dies wurde bisher unterbunden durch Hakenplatten oder durch eine Kugelgelenkplatte. Erstere schränken die Drehbeweglichkeit ein und es besteht die Ge­ fahr des ungewollten "Aushakens", letztere ist zwar auf Zugbelastung ausgelegt, wird bei Anschlagen der zueinander beweglichen Teile ungewollt doch auf Biegung (vermutlich auch noch durch relativ hohe Drehträgheitskräfte des Armes) belastet, was zum Implantatsbruch führt.This problem can be exemplified by the shoulder corner joint are clearly explained. It forms the link le between the clavicle and a smaller one external bones. Above and below the bone cone tact the two bones touching each other Tapes held together. Tear them up, they can Remove bones from each other. So far this has been prevented by hook plates or by a ball joint plate. The former restrict the mobility and there is Ge drive the unwanted "unhooking", the latter is open Tensile load is designed when the to each other moving parts unintentionally on a bend (probably also due to relatively high rotational inertia forces of the arm) burdened, which leads to implant breakage.

Aus der FR-PS 00 64 546 ist zwar eine Vorrichtung zum Zusam­ menhalten der Teile des menschlichen Schulter-Eck-Gelenkes bekannt, bei dem am Schlüsselbein und auf dem Acromium jeweils eine Platte befestigt ist und ein Gelenk die beiden Platten miteinander verbindet. Das Gelenk besteht jedoch aus einem Stiel, der an der einen Platte befestigt ist, und einer Kugel am Stielende, die in einer kugelförmigen Ausneh­ mung der anderen Platte ruht. Dieses Gelenk weist den bedeu­ tungsvollen Nachteil auf (weil mit seinem Versagen eine neuerliche Operation verbunden ist), daß es im Anschlagsbe­ reich des Kugelstiel-Elementes spontan biegesteif wird und diese Biegespannungen im Stiel zum Ermüdungsbruch führen. Während bei der Fixierung von Knochenbrüchen vom Implantat verlangt wird, daß es möglichst gegen alle Standardlastfälle hinreichend steif dimensioniert ist, wird bei Bänderrissen im Gelenkbereich eine Beweglichkeit des Gelenkes verlangt, um dessen Versteifung während der Heilung des Bandschadens auszuschließen. Von einem solchen Inplantat wird also we­ sentlich erwartet, daß es die Kontaktflächen der beiden sich im Gelenk berührenden Knochen zwar nahe beieinander hält, d. h. es muß zugfest sein, ansonsten aber die Beweglichkeit des Gelenkes möglichst wenig beeinträchtigt.From FR-PS 00 64 546 is a device for together holding the parts of the human shoulder-corner joint known, on the clavicle and on the acromium one plate each is attached and one joint the two Connects panels together. However, the joint consists of a handle attached to one plate, and a ball at the end of the stem, in a spherical recess rest of the other plate. This joint shows the meaning inconvenient disadvantage (because with his failure a new operation is connected) that it is in the attack realm of the spherical stem element spontaneously becomes rigid and these bending stresses in the handle lead to fatigue failure.  While fixing broken bones from the implant it is required that it be against all standard load cases if possible is dimensioned sufficiently rigid, in the event of ligament tears requires mobility of the joint in the joint area, to stiffen it during the healing of the ligament damage to exclude. Such an implant becomes we Expect it to be the contact surfaces of the two themselves in the joint touching bones holds close together, d. H. it must be tensile, but otherwise the mobility of the Joint affected as little as possible.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine zugfeste Verbindung der Ankerteile zu bieten, die eine nahezu unbegrenzte Ermüdungsfestigkeit aufweist, bei Biege­ belastung nicht bricht und auch nicht nur eine durch starre Teile allzu begrenzte Drehbeweglichkeit aufweist.The object underlying the invention is to offer a tensile connection of the anchor parts, the one has almost unlimited fatigue strength when bending load does not break and not only one due to rigid Parts has too limited rotational mobility.

Die Lösung ist im kennzeichnenden Teil des Anspruches 1 beschrieben.The solution is in the characterizing part of claim 1 described.

Die übrigen Ansprüche geben vorteilhafte Weiterbildungen und Ausführungsformen der Erfindung an.The remaining claims give advantageous developments and Embodiments of the invention.

Der besondere Vorteil der Erfindung ist darin zu sehen, daß keine lokale Flexibilität durch ein Gelenk mit notwendig begrenzter Beweglichkeit vorherrscht, sondern eine praktisch unbegrenzte Beweglichkeit durch eine verteilte Flexibilität über die gesamte Länge des Stahlseils zwischen den Ankerele­ menten gewährleistet ist.The particular advantage of the invention is that no local flexibility due to a joint limited mobility, but a practical one unlimited mobility thanks to distributed flexibility over the entire length of the steel cable between the anchor elements ment is guaranteed.

Die Erfindung wird im folgenden anhand dreier Ausführungs­ beispiele mittels der Fig. 1 bis 3 näher erläutert.The invention is explained below with reference to three examples of execution by means of FIGS. 1 to 3.

Das im Prinzip in Fig. 1 und als Clavicula-Platte in Fig. 2 vorgeschlagene Implantat besteht aus zwei Verankerungs- oder Befestigungselementen 1 und 2, die an den beiden gelenkig zu verbindenen Knochen (nicht dargestellt) angebracht, z. B. angeschraubt werden. Als biegeweiche Verbindung dient nun ein Stahlseil 3, das einfach oder mehrfach zwischen den Befestigungselementen 1, 2 verläuft. Da jeder Einzeldraht des Seiles 3 aus z. B. Stahl seine eigene neutrale Faser bezüglich Biegebelastung hat, verträgt dieses Verbindungs­ element 3 fast beliebige Verdrehungen der verbundenen Kno­ chenteile zueinander. Ein Bruch ist damit völlig ausge­ schlossen und ein guter Ersatz für reale Bänder geschaffen.The implant proposed in principle in FIG. 1 and as a clavicle plate in FIG. 2 consists of two anchoring or fastening elements 1 and 2 , which are attached to the two articulated bones (not shown), e.g. B. screwed. A steel cable 3 , which runs one or more times between the fastening elements 1 , 2 , now serves as a flexible connection. Since each individual wire of the rope 3 from z. B. steel has its own neutral fiber with respect to bending stress, this connection element 3 tolerates almost any twists of the connected bone chent parts to each other. A break is completely excluded and a good replacement for real tapes is created.

Als Führungselemente für die beiden Schlingen 4 und 5, die von dem Seil 3 gebildet werden, dienen durchgehende Bohrun­ gen 1′-1′′′ bzw. 2′ bis 2 IV oder 2′-2′′′ auf den beiden Verankerungs- bzw. Befestigungselementen 1 und 2. Die Boh­ rungen 1′-1′′′ und 2′-2′′′ bilden ein Dreieck und die Bohrungen 2′-2IV ein Doppeldreieck mit jeweils abgerunde­ ten Ecken. Das Seil 3 ist in den Bohrungen verlegt. Im eigentlichen Gelenkbereich 6 zwischen den Verankerungs- bzw. Befestigungselementen 1 und 2 verlaufen die Stahlseilberei­ che parallel zueinander (wie dargestellt) oder sie überkreu­ zen sich, wozu allerdings zumindest die aufeinanderzulaufen­ den Bohrungen 1′′-2′′ und 1′′′-2′ in Richtung und Höhe entsprechend ausgerichtet sein müssen.As guide elements for the two loops 4 and 5 , which are formed by the rope 3 , through holes gene 1 '- 1 ''' or 2 'to 2 IV or 2 ' - 2 '''on the two anchoring or Fasteners 1 and 2 . The Boh stanchions 1 '- 1 ''' and 2 '- 2 ''' form a triangle and the holes 2 '-2 IV a double triangle, each with rounded corners. The rope 3 is laid in the holes. In the actual joint area 6 between the anchoring or fastening elements 1 and 2 , the steel cable areas run parallel to one another (as shown) or they cross over, which, however, at least means that the holes 1 '' - 2 '' and 1 '''- converge 2 'must be aligned accordingly in the direction and height.

Ein besonderer Vorteil beim Ausführungsbeispiel einer Clavi­ culaplatte nach Fig. 2 besteht in der Möglichkeit des suk­ zessiven Anbringens der Elemente 1 und 2, was das operative Vorgehen erleichtert.A particular advantage in the embodiment of a clavi culaplatte according to FIG. 2 is the possibility of successively attaching the elements 1 and 2 , which simplifies the surgical procedure.

In Fig. 3 ist eine weitere Möglichkeit der Aneinanderhalte­ rung der beiden Befestigungselemente 1 und 2 (nicht darge­ stellt) anstelle des Seils 3 beschrieben. Es handelt sich um die Kombination Spannschraube 6 - Kortikalisschraube 7, wobei jeweils eines der beiden Teile an einer der Befesti­ gungselemente 1 bzw. 2 angeordnet ist. Beide Teile 6 und 7 werden mittels der Zugschraube 8 zusammengehalten, die in ihrem mittleren, meist freiliegenden Bereich zwischen den Befestigungselementen 1 und 2 zu einem flexiblen Seilstück 9 ausgebildet ist.In Fig. 3 another way of holding together the two fasteners 1 and 2 (not Darge provides) is described instead of the rope 3 . It is the combination clamping screw 6 - cortex screw 7 , one of the two parts of one of the fastening elements 1 and 2 is arranged. Both parts 6 and 7 are held together by means of the tension screw 8 , which is formed into a flexible cable piece 9 in its central, mostly exposed area between the fastening elements 1 and 2 .
