Abstract

The inter articular disk prosthesis comprises spiral (3) which is made of a metal with memory, and has spherical ends (4) extending into the prosthesis coupling knobs (5). As a result of the spring force of the spiral, the coupling knobs are securely seated in the base and cover plate of the adjacent vertebras. Pimply surfaces (6) of the prosthesis promote bonding of the latter to the adjacent vertebras.

Description

Die Erfindung betrifft eine Bandscheibenprothese, die den Ersatz der kompletten Bandscheibe an der Halswirbelsäule zum Ziel hat und sich biomechanisch wie eine natürliche Bandscheibe verhalten soll. The invention relates to an intervertebral disc prosthesis having to replace the entire disc of the cervical spine to the target and should behave like a natural disc biomechanically.

An der Halswirbelsäule kommt es nach operativer Ausschaltung eines Bewegungssegmentes (ventrale zervikale Fusion) zu einer Mehrbelastung der Bandscheiben in den benachbarten Bewegungssegmenten mit der Folge einer sogenannten "Anschlussinstabilität" und vorzeitigen Bandscheibendegeneration. On the cervical spine occurs after surgical elimination of a motion segment (anterior cervical fusion) to an additional burden of the discs in the adjacent motion segments, resulting in a so-called "connection instability" and premature disc degeneration. POSPIECH und Mitarbeiter (1996) haben dieses Phänomen an humanen Halswirbelsäulen experimentell nachgewiesen. POSPIECH and colleagues (1996) have demonstrated this phenomenon in human cervical experimentally. Sie konnten belegen, dass bei der ventralen Verblockung eines Bandscheibensegmentes das eingebrachte Implantat nicht in der Lage ist, die sonst von einer intakten Bandscheibe abgefangenen Belastungen abzumildern. They could prove that the inserted implant is not in a position at the ventral blocking a disc segment to mitigate the otherwise intercepted by an intact disc loads. Die geänderte Belastungsverteilung führt demnach zu einer Mehrbeanspruchung der Bandscheiben in den Nachbarsegmenten, insbesondere des unteren. The modified stress distribution accordingly leads to a more stress on the intervertebral discs in the neighboring segments, in particular of the bottom.

Vor diesem Hintergrund ist es die Aufgabe der vorliegenden Erfindung, mit einer künstlichen Halswirbelsäulen-Bandscheiben-Prothese die natürliche Bandscheibenfunktion zu simulieren. Against this background it is the object of the present invention to simulate the natural disc function by an artificial cervical spine intervertebral disc prosthesis.

Bei der Prothese (CIDPS) handelt es sich um ein osmotisch aktives polymeres Hydrogel, das von einer gewebten Polyethylen-Hülle umgeben ist und eine definierte Wasseraufnahmekapazität besitzt. In the prosthesis (CIDPS) is an osmotically active polymer hydrogel, which is surrounded by a woven polyethylene sheath and a defined water absorption capacity has. Die Steifigkeit der Prothese wird durch die Federkraft einer in die Polyäthylen-Hülle eingebrachten Spirale aus Titan- Nickel-Memorymetalldraht gewährleistet, die das Implantat fest in den Zwischenwirbelraum einklemmt. The stiffness of the prosthesis is ensured by the spring force of a introduced into the polyethylene sheath spiral of titanium-nickel-memory metal wire, which clamps the implant firmly into the intervertebral space. Die noppenförmig gestaltete Oberfläche der gewebten Polyethylen-Hülle erlaubt einen knöchernen Einbau der Prothese im Grund- und Deckplattenbereich der benachbarten Wirbelkörper. The knob-like shaped surface of the woven polyethylene sheath allows a bony incorporation of the prosthesis in the base and cover plate portion of the adjacent vertebral bodies. Zur Verhinderung einer Prothesendislokation ist das Implantat deckplattenwärts an beiden Seiten mit zentralabragenden halbkugelförmigen Sicherungszapfen versehen, die mit dem Memorymetalldraht in Verbindung stehen und korrespondierend in die vorgefrästen Öffnungen der Grund- und Deckplatte der benachbarten Wirbelkörper zu liegen kommen. For preventing Prothesendislokation the implant is cover plate Windwärts provided on both sides with zentralabragenden hemispherical securing pins which are associated with the memory metal wire in connection, and correspondingly the adjacent vertebral bodies come to lie in the pre-milled openings of the base and cover plates.

Mit einer speziellen Implantationszange, die eine temporäre Kompression des Implantates ermöglicht, wird die Bandscheibenprothese von ventral in den Zwischenwirbelraum eingebracht. With a special implantation forceps, which allows a temporary compression of the implant, the intervertebral disc prosthesis is introduced from the anterior side into the intervertebral space.

Die Zeichnungsfiguren zeigen schematisch eine Schnittansicht der Bandscheibenprothese und einen Ausschnitt der Implantationszange. The drawing figures schematically show a sectional view of the intervertebral disc prosthesis and a section of the implantation gun.
