Abstract

Device for the in vivo fitting of a cruciform ligament prosthesis or for fitting prostheses for other types of ligament. The end of the cruciform ligament prosthesis emerges from a drilling in the bone and is fastened to the surface of the bone. The device is formed in such a way that the cruciform ligament prosthesis is fixed to achieve durable prosthesis stability primarily through static friction, and to ensure minimum relative movement between the ligament and bone. The device is characterized by a ligament anchor, consisting of a shaft, which may be introduced into the drilling, and an anchor tab, to be fastened to the surface of the bone, the shaft and anchor tab being orientated at an angle to one another.

Description

Vorrichtung zur in-vivo-Befestigung eines Kreuzbandersatzes am Knochen Device for in-vivo attachment of a cruciate ligament replacement to the bone
Die Erfindung betrifft eine Vorrichtung zur in-vivo-Befestigung eines Kreuzbandersatzes oder zur Befestigung des Ersatzes anderer Bänder, wobei das Ende des Kreuzbandersatzes aus einem Bohrkanal im Knochen austritt und an der Knochenoberfläche gehaltert wird.The invention relates to a device for in vivo fastening of a cruciate ligament replacement or for fastening the replacement of other ligaments, the end of the cruciate ligament replacement emerging from a drilling channel in the bone and being held on the bone surface.
Der operative Ersatz für das Kreuzband, z. B. des menschlichen Kniegelenkes erfolgt meist mit einer Methode, bei der das Kreuzband zwischen den beiden Rollhügeln des Femur hindurchgezogen und seitlich oberhalb eines der Rollhügel bzw. an der Tibia mechanisch befestigt wird. Als Befestigungsmittel der Enden des Kreuzbandes an den Knochenteilen dienen U- Krampen, Zackenkranzschrauben oder in den Bohrkanal eingebolzte Knochenstücke (Walter Blauth, "Orthopädi sch-chirugisehe Operationen am Knie", G. Thieme Verlag, 1986, Nr. 156 - 158).The operative replacement for the cruciate ligament, e.g. B. the human knee joint is usually done with a method in which the cruciate ligament is pulled between the two rolling mounds of the femur and mechanically attached laterally above one of the rolling mounds or on the tibia. U-clamps, serrated screws or bone pieces bolted into the drill channel serve as fastening means for the ends of the cruciate ligament on the bone parts (Walter Blauth, "Orthopedic surgical surgery on the knee", G. Thieme Verlag, 1986, No. 156-158).
Diese Art der Befestigung der Enden des Kreuzbandes ist, zumindest auf Langzeitbeanspruchungen bezogen, für alle Patienten nicht ohne Risiko, denn Ausreißungen in der Bandstruktur sind unvermeidbar. Zudem bieten sie zu wenig Haftreibung, so daß eine Relativbewegung zwischen Kreuzbandersatz und tran skondy lerem Bυhrkanal praktisch nicht zu verhindern ist, wodurch der Einwachsprozeß evtl. verzögert oder gar verhindert werden kann.This type of attachment of the ends of the cruciate ligament is, at least in relation to long-term stress, not without risk for all patients, because tears in the ligament structure are unavoidable. In addition, they offer too little static friction, so that a relative movement between cruciate ligament replacement and transparent skeletal bore canal is practically unavoidable, which may delay or even prevent the waxing process.
Die der Erfindung zugrundeliegende Aufgabe besteht darin, die Vorrichtung der e. g. Art derart auszubilden, daß der Kreuzbandersatz zur Erlangung der Langzeitfestigkeit im prothetischen Sinne vorwiegend durch Haftreibung fixiert und eine Minimierung der Relativbewegungen zwischen Band und Knochen erreichbar wird.The object of the invention is to provide the device of the e. G. Type in such a way that the cruciate ligament replacement to achieve long-term strength in the prosthetic sense is mainly fixed by static friction and a minimization of the relative movements between the ligament and the bone can be achieved.
Die Lösung ist mit den kennzeichnenden Merkmalen des Anspruches 1 beschrieben. Die übrigen Ansprüche geben vorteilhafte Weiterbildungen undThe solution is described with the characterizing features of claim 1. The other claims give advantageous developments and
Ausführungsformen der Erfindung an.Embodiments of the invention.
Auf besonders vorteilhafte Weise wird mit dem erfindungsgemäßen Vorschlag die Relativbewegung zwischen Bandersatz und Knochenbohrkanal minimiert, wozu die Stöpselwirkung des Ankerschaftes bzw. -halses einen erheblichen Beitrag leistet. Diese Art der Befestigung begünstigt das Einwachsen des Kreuzbandersatzes, indem seine Querkontraktionen unterdrückt werden. Die bangzeitfestigkeit des Kreuzbandes ist hiermit eher gegeben.In a particularly advantageous manner, the relative movement between the ligament replacement and the bone drilling channel is minimized with the proposal according to the invention, for which the plugging effect of the anchor shaft or neck makes a considerable contribution. This type of attachment promotes the ingrowth of the cruciate ligament replacement by suppressing its transverse contractions. This means that the cruciate ligament is more resistant to anxiety.
Die Erfindung wird im folgenden anhand zweier Ausführungsbeispiele mittels der Fig. 1 - 4 näher erläutert.The invention is explained in more detail below with reference to two exemplary embodiments using FIGS. 1-4.
Die Fig. 1 - 3 stellen einen (metallischen) Kreuzbandanker 1 sowie seine Befestigung an einem Knochen dar. Er besteht aus einem Schaft 2 und einem Ankerfuß 3, die im Winkel α zueinander ausgerichtet sind. Der Winkel α hängt vom Ort der Befestigung am Knochen 4 (s. Fig. 3) ab und kann kleiner/ größer als 90° sein. Während der Schaft 2 kreiszyl inderförmig ausgeführt ist, so daß er in den Bohrkanal 5 (s. Fig. 3) eingepaßt werden kann, wird der Ankerfuß 3 von einem abgeplatteten Stück gebildet. In der Übergangszone zwischen Schaft 2 und Ankerfuß 3 befindet sich die Abknickzone (Winkel α).1-3 show a (metallic) cruciate ligament anchor 1 and its attachment to a bone. It consists of a shaft 2 and an anchor base 3, which are aligned at an angle α to one another. The angle α depends on the location of the attachment to the bone 4 (see FIG. 3) and can be smaller / larger than 90 °. While the shaft 2 is circular-cylindrical, so that it can be fitted into the drilling channel 5 (see FIG. 3), the anchor base 3 is formed by a flattened piece. The kink zone (angle α) is located in the transition zone between shaft 2 and anchor foot 3.
Der Schaft 2 ist an seinem freien Ende 6 mittels einer Kerbe 7 zu einem Kopf ausgebildet. In diese Kerbe 7 kann der Knochen 4 einwachsen. Die Abmessungen des Schaftes 2 entsprechen den Anforderungen an Kreuzbandersatz 8 oder dem Ersatz für andere Bänder und Bohrkanal 5 (s. Fig. 3).The shaft 2 is formed at its free end 6 into a head by means of a notch 7. The bone 4 can grow into this notch 7. The dimensions of the shaft 2 correspond to the requirements for cruciate ligament replacement 8 or the replacement for other ligaments and drilling channel 5 (see FIG. 3).
Der Ankerfuß 3 ist gemäß Fig. 2 gegen sein freies Ende 9 zu mit einer Bohrung 10 versehen, durch die eine Befestigungsschratibe 11 (Fig. 3) geführt werden kann. Sie dient der Halterung sowohl des Kreuzbandersatzes 8 als auch des Kreuzbandankers 1 am Knochen 4, z. B. der Tibia. Diese Befestigungsart ist in Fig. 3, von der Seite her gesehen, dargestellt. Durch die Tibia 4 ist der Bohrkanal 5 gebohrt, der an der Oberfläche 12 austritt. Der Kreuzbandersatz 8 ist in diesem Bohrkanal 5 verlegt. Sein Ende 13 ragt jedoch über die Oberfläche 12 hinaus und wird vom Ankerfuß 3 mittels der dem Knochen 4 zuzuwendenden Oberfläche 14 (Winkel entspricht der Oberflächenkrümmung) an die Oberfläche 12 gepreßt. Zusätzlich ist das Ende 13 mittels einer 180°- Bandumlenkung um das freie Ende 9 des Ankerfusses 3 zur dem Knochen 4 abgewandten Oberfläche 15 herumgebogen und auch noch von dieser Vorderseite 15 (also doppelt) her über die Schraube 11 (z. B. Zackenkreuzschraube) sowohl am Ankerfuß 3 als auch am Knochen 4 befestigt. Diese Art der Befestigung bewirkt eine enorme Haftreibung zwischen Kreuzbandersatz 8 und Ankerfuß 3.2 is provided with a bore 10 through its free end 9, through which a fastening plate 11 (FIG. 3) can be guided. It serves to hold both the cruciate ligament replacement 8 and the cruciate ligament anchor 1 on the bone 4, for. B. the tibia. This type of attachment is shown in Fig. 3, seen from the side. The drilling channel 5, which emerges on the surface 12, is drilled through the tibia 4. The cruciate ligament replacement 8 is laid in this drill channel 5. However, its end 13 protrudes beyond the surface 12 and is pressed against the surface 12 by the anchor foot 3 by means of the surface 14 facing the bone 4 (angle corresponds to the surface curvature). In addition, the end 13 is bent around the free end 9 of the anchor foot 3 to the surface 15 facing away from the bone 4 by means of a 180.degree. attached to both the anchor foot 3 and the bone 4. This type of attachment causes enormous static friction between the cruciate ligament replacement 8 and the anchor foot 3.
Die physiologische Bandbelastung FB zieht demnach den Kreuzbandanker 1, insbesondere den Schaft 2, in den Bohrkanal 5 hinein. Dies führt zu einer Pressung an die Knochenbereiche in der Abknickzone des Kreuzbandankers 1. Die Haftung zwischen Kreuzbandersatz 8 und Knochen 4 wird erhöht.The physiological ligament loading F B accordingly pulls the cruciate ligament anchor 1, in particular the shaft 2, into the drilling channel 5. This leads to a pressure on the bone areas in the kink zone of the cruciate ligament anchor 1. The adhesion between cruciate ligament replacement 8 and bone 4 is increased.
Anstelle der Schraube 11 ist auch eine Schrauben/Schellen-Anordnung als Befestigungsmittel des freien Endes 13 des Kreuzbandersatzes 8 denkbar.Instead of the screw 11, a screw / clamp arrangement is also conceivable as a fastening means for the free end 13 of the cruciate ligament replacement 8.
Eine weitere Gestaltungsart des Kreuzbandankers 1 ist in Fig. 4 dargestellt. Die Konstruktionsmerkmale des Schaftes 2 sowie des Ankerfusses 3 sind im Prinzip die gleichen wie die in Fig. 1 - 3 beschriebenen. Lediglich seine Befestigungsart am Knochen 4 bzw. die des Kreuzbandersatzes 8 mit seinem freiem Ende am Knochen 4 weicht ab. Anstelle von Schrauben bzw. Schrauben/Schellen-Anordnungen sind an der dem Knochen 4 zugewendeten Oberfläche 14 des Ankerfusses 3 zumindest einseitig randseitig Zahnreihen 16 (Krallzähne) angeordnet, die in den Knochen 4 eingeschlagen werden und somit die Haiterung sowohl des Kreuzbandersatzes 8 als auch des Kreuzbandankers 1 bewirken. Another type of design of the cruciate ligament anchor 1 is shown in FIG. 4. The design features of the shaft 2 and the anchor base 3 are in principle the same as those described in FIGS. 1-3. Only its method of attachment to bone 4 or that of cruciate ligament replacement 8 with its free end to bone 4 differs. Instead of screws or screw / clamp arrangements, tooth rows 16 (claw teeth) are arranged on the surface 14 of the anchor foot 3 facing the bone 4 at least on one side, which are hammered into the bone 4 and thus the hardening of both the cruciate ligament replacement 8 and the Effect cruciate ligament anchor 1.
