Abstract
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 which Replacement of the entire intervertebral disc on the cervical spine aims and biomechanically like a natural one Intervertebral disc should behave.
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. POSPIECH und Mitarbeiter (1996) haben dieses Phänomen an humanen Halswirbelsäulen experimentell nachgewiesen. 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. Die geänderte Belastungsverteilung führt demnach zu einer Mehrbeanspruchung der Bandscheiben in den Nachbarsegmenten, insbesondere des unteren.At the cervical spine it comes after surgery Deactivation of a movement segment (ventral cervical fusion) to an additional burden on the Intervertebral discs in the adjacent movement segments with the consequence of a so-called "connection instability" and premature disc degeneration. POSPIECH and co-workers (1996) have this phenomenon on human cervical spine experimentally proven. They were able to demonstrate that ventral locking the inserted implant of a disc segment unable to do so from an intact Mitigate intercepted loads. The changed load distribution leads to a Excessive stress on the intervertebral discs in the Neighboring segments, especially the lower one.
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 task of present invention, with an artificial Cervical spinal disc prosthesis the natural one To simulate intervertebral disc function.
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. 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. Die noppenförmig gestaltete Oberfläche der gewebten Polyethylen-Hülle erlaubt einen knöchernen Einbau der Prothese im Grund- und Deckplattenbereich der benachbarten Wirbelkörper. 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.The prosthesis (CIDPS) is a polymeric hydrogel osmotically active, which from a woven polyethylene shell is surrounded and one has a defined water absorption capacity. The Rigidity of the prosthesis is determined by the spring force in one the spiral made of titanium Nickel memory metal wire ensures that The implant is firmly clamped in the intervertebral space. The knob-shaped surface of the woven Polyethylene shell allows the bony installation of the Prosthesis in the base and cover plate area of the adjacent vertebrae. To prevent a Dislocation of the prosthesis is towards the cover plate on both sides with central cantilever hemispherical locking pin provided with are connected to the memory metal wire and corresponding in the pre-milled openings of the Base and cover plate of the adjacent vertebrae too come to lie.
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, the one allows temporary compression of the implant the intervertebral disc prosthesis from ventral to the Intervertebral space introduced.
Die Zeichnungsfiguren zeigen schematisch eine Schnittansicht der Bandscheibenprothese und einen Ausschnitt der Implantationszange. The drawing figures schematically show one Sectional view of the intervertebral disc prosthesis and one Section of the implantation forceps.
