Description

Knochenschraube zur Verbindung der Enden von zwei Knochen, wie Schien- und Wadenbein Die Erfindung betrifft eine Knochenschraube zur Verbindung der Enden von zwei Knochen, wie Schien-und Wadenbein, die ein gabelähnliches Pfannenlager zur kugelgelenkartigen Abstützung auf einen Knöchel bilden, bestehend aus einer Schraube mit Flachkopf und Mutterstück.Bone screw for connecting the ends of two bones, such as tibia and fibula. The invention relates to a bone screw for connecting the ends of two bones, such as the tibia and fibula, which form a fork-like socket bearing to form a ball joint-like support on an ankle, consisting of a Flat head screw and nut piece.

Es sind Knochenschrauben bekannt, bei denen auf beiden mit Gewinde versehenen Enden je eine Mutter aufgeschraubt wird. Dabei hat man die Bohrung durch die beiden zu verbindenden Knochenenden so gelegt, daß es nichts ausmacht, wenn die Muttern sich.nur in einer senkrecht zum Schraubenschaft gerichteten Ebene abstützen können. Bone screws are known in which both are threaded a nut is screwed on each end provided. You have the hole through the two ends of the bones to be connected are placed in such a way that it does not matter if the nuts only support themselves in a plane perpendicular to the screw shaft can.

Es hat sich aber gezeigt, daß es sinnvoller ist, bei Verletzungen bzw. Beschädigungen des oberen Sprunggelenkes die zur Heilung benutzten Knochenschrauben so legen zu können, daß die beim Gehen auftretenden Bewegungen auch während der Behandlung möglich sind. Es wird damit gewährleistet, daß die Heilung des beschädigten Bandapparates des oberen Sprunggelenkes während der Behandlung mittels der Knocheuschraube so vonstatten geht, daß die beim Gehen beste Lage der Knochenenden und des sogenannten Bandapparates gewissermaßen zwangläufig herbeigeführt wird. But it has been shown that it makes more sense for injuries or damage to the upper ankle joint, the bone screws used for healing to be able to lay that the movements that occur when walking also during the Treatment are possible. It will thus ensure that the healing of the damaged Ligamentous apparatus of the upper ankle joint during treatment using the bone screw proceeds in such a way that the bone ends and the so-called bone ends are in the best position when walking Band apparatus is, as it were, inevitably brought about.

Die so festgelegte Forderung zur wirksamsten Behandlung beschädigter Bandapparate wird durch eine Knochenschraube erfüllt, die erfindungsgemäß dadurch gekennzeichnet ist, daß die Schraube einen starr und fest damit verbundenen schildförmigen Kopf aufweist, dessen Tangentialebene im Berührungspunkt mit dem Schraubenschaft einen spitzen Winkel mit der Schraubenachse bildet, und daß das Mutterstück in an sich bekannter Weise die Form eines runden gewölbten Tellers mit von einem Mittelloch ausgehenden radialen Einschnitten und dadurch gebildeten federnden Zungen aufweist. Das Gewindeende des Schraubenschaftes ist zweckmäßig im Verhältnis zu der zur eigentlichen Verbindung der beiden Knochen erforderlichen Länge derart verlängert, daß ein Werkzeug daran befestigt und zum Spannen des Mutterstückes auf dem Schraubenschaft und zum langsamen Herholen des abgesprengten Wadenbeins mittels des schildförmigen Schraubenkopfes benutzt werden kann. The so established requirement for the most effective treatment of damaged Ligamentous apparatus is fulfilled by a bone screw, which according to the invention thereby is characterized in that the screw has a rigid and firmly connected shield-shaped Has head whose tangential plane at the point of contact with the screw shank forms an acute angle with the screw axis, and that the nut piece in at known way the shape of a round arched plate with a central hole having outgoing radial incisions and resilient tongues formed thereby. The threaded end of the screw shaft is useful in relation to the actual one Connection of the two bones required length extended so that a tool attached to it and for tensioning the nut piece on the screw shaft and for Slowly bring back the detached fibula by means of the shield-shaped screw head can be used.

Durch die erfindungsgemäße Maßnahme der winkligen Anordnung des Flachkopfes am Schraubenschaft ist der späteren angenehmsten Auflage des Flachkopfes auf dem einen Knochenende Rechnung getragen, während die Ausbildung von federnden Zungen am Mutterstück die während der Benutzung beim Gehen auftretenden Änderungen des Winkels der Auflageebene des Mutterstückes in bezug auf den Schraubenschaft ermöglicht. By the measure according to the invention of the angled arrangement of the flat head on the screw shaft is the later most comfortable support of the flat head on the a bone end taken into account while the formation of resilient tongues the changes of the Allows angle of the support plane of the nut piece with respect to the screw shank.

Darüber hinaus läßt sich eine solche Mutter durch Aufdrücken ohne Verschraubung schnell auf dem Gewindeende des Schraubenschaftes fest anziehen, was die operative Behandlung des Patienten beschleunigt und erleichtert. In addition, such a nut can be pressed on without it Quickly tighten the screw connection on the threaded end of the screw shaft, what the surgical treatment of the patient accelerated and facilitated.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. An embodiment of the invention is shown in the drawing.

Fig. 1 zeigt in Seitenansicht ein Röntgenbild des Sprunggelenks mit den Konturen der eingesetzten Knochenschraube, und Fig. 2 zeigt dasselbe Sprunggelenk von vorn gesehen, ebenfalls mit den Konturen der Knochenschraube im Röntgenbild. Fig. 1 shows a side view of an X-ray image of the ankle joint the contours of the inserted bone screw, and FIG. 2 shows the same ankle joint Seen from the front, also with the contours of the bone screw in the X-ray image.

Der Schaft 1 der Schraube durchdringt Schienbein 2 und Wadenbein 3. Wie aus Fig. 2 hervorgeht, legt sich die Platte 4 mit entsprechender Wölbung an das Wadenbein 3 an. Die lösbare Platte 5 ist gemäß Fig. 1 von der Bohrung 6 aus mit vier radialen Schlitzen 7 versehen, so daß sich federnde Zungen 8 bilden, welche in das Gewinde 9 einrasten. Es ist noch nachzutragen, daß 10 den Fußknöchel darstellt, der mit einer balligen Fläche 11 die Abstützung des Schienbeins 2 übernimmt. The shaft 1 of the screw penetrates the tibia 2 and fibula 3. As can be seen from FIG. 2, the plate 4 lies down with a corresponding curvature on fibula 3. The detachable plate 5 is from the bore 6 according to FIG provided with four radial slots 7 so that resilient tongues 8 form which Engage in thread 9. It should be added that 10 represents the ankle, which takes over the support of the tibia 2 with a spherical surface 11.

Zur Einführung und Verspannung des Mutterstückes auf dem Schraubenschaft ist ein besonderes Spannwerkzeug vorgesehen, welches gestattet, durch einen stetigen und wohlausgeglichenen Druck auf die Spannplatte dieselbe immer weiter nach innen einrasten zu lassen und auf diese Weise das abgesprengte Wadenbein langsam herzuholen. For introducing and bracing the nut piece on the screw shaft a special clamping tool is provided, which allows a steady and well-balanced pressure on the clamping plate the same more and more inward to snap into place and in this way to slowly bring the detached fibula.
