Abstract

Künstliches Bandscheibenersatz-System, umfassend: einen Kern (130); eine obere Endplatte (136) zur Befestigung an einem oberen Wirbel; eine untere Endplatte (138) zur Befestigung an einem unteren Wirbel; ein Paar paralleler, an der Außenfläche einer der Endplatten gebildeter Kiele; einen einzelnen mittig angeordneten, an der Außenfläche der anderen Endplatte gebildeten Kiel; wobei der Kern (130) in einer in der oberen Fläche der unteren Endplatte (138) gebildeten Rinne (142) positioniert ist und die Rinne am posterioren oder anterioren Ende offen ist.

Claims (15)

  1. Künstliches Bandscheibenersatz-System, umfassend: einen Kern (130); eine obere Endplatte (136) zur Befestigung an einem oberen Wirbel; eine untere Endplatte (138) zur Befestigung an einem unteren Wirbel; ein Paar paralleler, an der Außenfläche einer der Endplatten gebildeter Kiele; einen einzelnen mittig angeordneten, an der Außenfläche der anderen Endplatte gebildeten Kiel; wobei der Kern (130) in einer in der oberen Fläche der unteren Endplatte (138) gebildeten Rinne (142) positioniert ist und die Rinne am posterioren oder anterioren Ende offen ist.
  2. Künstliches Bandscheibenersatz-System nach Anspruch 1, wobei der Kern (130) eine Halbkugelform mit einer abgeflachten unteren Fläche, welche in die Rinne passt, aufweist.
  3. Künstliches Bandscheibenersatz-System nach Anspruch 1 oder 2, wobei das Paar paralleler Kiele aus parasagittalen Kielen besteht.
  4. Künstliches Bandscheibenersatz-System nach Anspruch 1 oder Anspruch 2, welches derart konfiguriert ist, dass der Kern (130) eingesetzt werden kann, indem der Kern (130) in die Rinne geschoben wird.
  5. Künstliches Bandscheibenersatz-System nach einem beliebigen vorangehenden Anspruch, wobei die Rinne sowohl in der anterioren/posterioren als auch der medialen/lateralen Richtung größer als der Kern ist.
  6. Künstliches Bandscheibenersatz-System nach einem beliebigen vorangehenden Anspruch, wobei die Rinne am anterioren Ende offen ist.
  7. Künstliches Bandscheibenersatz-System nach einem beliebigen vorangehenden Anspruch, welches ferner einen Arretiermechanismus umfasst, um zu verhindern, dass der Kern (130) aus der Rinne ausgestoßen wird.
  8. Künstliches Bandscheibenersatz-System nach einem beliebigen der Ansprüche 1 bis 6, wobei die Rinne einen Anschlag (144) aufweist, welcher derart konfiguriert ist, dass der Kern (130) daran gehindert wird, sich aus der Rinne hinauszubewegen.
  9. Künstliches Bandscheibenersatz-System nach einem beliebigen vorangehenden Anspruch, wobei die Unterfläche der oberen Endplatte (136) derart geformt ist, dass sie der oberen Fläche des Kerns (130) entspricht.
  10. Künstliches Bandscheibenersatz-System nach einem beliebigen der Ansprüche 1 bis 8, wobei die Unterfläche der oberen Endplatte (136) flach ist, um an eine abgeflachte obere Fläche (144) des Kerns (130) anzugreifen.
  11. Künstliches Bandscheibenersatz-System nach einem beliebigen vorangehenden Anspruch, wobei die Endplatten Titan oder eine Titanlegierung, Chrom-Kobalt-Malybdän (CoCrMo), Kobalt 28-Chrom-Molybdän, Kobalt-Chrom-Legierung oder nichtrostenden Stahl enthalten.
  12. Künstliches Bandscheibenersatz-System nach einem beliebigen der Ansprüche 1 bis 10, wobei die Endplatten Titan oder eine Titanlegierung enthalten.
