Abstract

The supporting element for holding two adjacent vertebrae in the spine at a distance consists of at least one flexible cushion which can be inserted in place of an intervertebral disc between two vertebrae.

Description

Die Erfindung betrifft ein Stützelement zum Halten zweier benachbarter Wirbel der Wirbelsäule auf Abstand. The invention relates to a support member for supporting two adjacent vertebrae of the spine at a distance.

Der Erfindung liegt die Aufgabe zugrunde, ein einfach aufgebautes Stützelement mit hoher Lebensdauer zu schaffen. The invention has for its object to provide a simply constructed support element with high durability.

Erfindungsgemäß wird diese Aufgabe durch Anwendung der Merkmale des Kennzeichens des Anspruchs 1 gelöst. According to the invention this object is achieved by applying the characterizing features of claim 1.

Ein weiterer Vorteil des erfindungsgemäßen Stützelementes ist darin zu sehen, daß es Bewegungen der Wirbelsäule wie in gesundem Zustand zuläßt und daß keine neben der Wirbelsäule zu implantierende Elemente erforderlich sind. Another advantage of the support element of the invention is the fact that it allows movement of the spine in a healthy state and that none are required in addition to the spine to be implanted elements.

Zwei Ausführungsbeispiele der Erfindung sind anhand der Zeichnung beschrieben. Two embodiments of the invention are described with reference to the drawing. In dieser zeigt: This shows:

Fig. 1 Teile einer Wirbelsäule in einem schematischen Längsschnitt, Fig. 1 parts of a spinal column in a diagrammatic longitudinal section,

Fig. 2 eine erste Ausführungsform des Stützelementes in einer Ansicht und Fig. 2 shows a first embodiment of the support element in a view, and

Fig. 3 eine zweite Ausführungsform eines Stützelementes in einer teilweise aufgebrochenen Ansicht. Fig. 3 shows a second embodiment of a support member in a partly broken view.

Fig. 1 zeigt einen Ausschnitt einer Wirbelsäule mit mehreren Wirbeln 1 zwischen denen zum Teil Bandscheiben 2 vorhanden sind. Fig. 1 shows a portion of a spinal column with a plurality of vertebrae between which 1 part of discs 2 are present. Zwischen zwei Wirbeln 1 ist die Bandscheibe entfernt und durch ein elastisches Kissen 3 ersetzt. 1 between two vertebrae, the intervertebral disc is removed and replaced by a resilient pad. 3 Das elastische Kissen 3 umfaßt eine Umhüllung 4 aus einem flexiblen Werkstoff. The elastic pad 3 comprises a casing 4 of a flexible material. In die Umhüllung 4 ist ein Fluid 5 , eingefüllt. In the casing 4 is a fluid 5, is filled. Dieses Fluid kann ein gasförmiges Medium, wie beispielsweise Luft, oder eine Flüssigkeit, wie beispielsweise Öl oder Siliconöl sein. This fluid may be a gaseous medium, such as air, or a liquid, such as oil or silicone oil. Der flexible Werkstoff der Umhüllung 4 ist körperverträglich und undurchlässig für das eingefüllte Fluid. The flexible material of the sheath 4 is compatible with the body and impervious to the fluid filled. Zweckmäßig ist die Umhüllung 4 nach dem Einfüllen des Fluids durch Verschweißen verschlossen. Suitably, the enclosure is closed after filling of the fluid 4 by welding. Wie Fig. 2 zeigt, weist das Kissen 3 in Draufsicht eine U-förmige, im eingesetzten Zustand den Wirbelkanal umgreifende Gestalt auf. As Fig. 2 shows, the cushion 3 in top view, a U-shaped, embracing the spinal canal when inserted shape.

Das Kissen 6 gemäß Fig. 3 weist eine in Draufsicht stabförmige Gestalt auf. The pad 6 according to FIG. 3 has a rod-like shape in plan view. Es besteht wiederum aus einer Umhüllung 7 , in die ein elastischer Werkstoff 8 , beispielsweise ein Schaumstoff eingebracht ist. It in turn consists of an envelope 7, in which an elastic material 8, for example, a foam is introduced. Bei Verwendung der Kissen 6 sind zwei Kissen parallel verlaufend oder drei im Dreieck angeordnete Kissen zur Abstützung zweier benachbarter Wirbel 1 zu implantieren. When using the pad 6 two pillows are running parallel or three arranged in a triangle cushion for supporting two adjacent vertebrae 1 to be implanted.

Eine weitere Ausführungsform sieht vor, daß das Kissen aus einem einheitlichen elastischen Werkstoff besteht. A further embodiment provides that the cushion is made of a uniform elastic material.
