Title (DE) ZWISCHENWIRBEL-IMPLANTAT MIT KOMPRIMIERBAREM HOHLKÖRPERPROFIL
(EN) INTERVERTEBRAL IMPLANT WITH COMPRESSIBLE SHAPED HOLLOW ELEMENT
(FR) IMPLANT INTERVERTEBRAL AVEC CORPS CREUX PROFILE ET COMPRESSIBLE
Abstract:
(DE) Das Zwischenwirbel-Implantat besteht aus einem abgeflachten Hohlkörperprofil (1) in Form eines Hohlzylinders, hohlen Kegelstumpfes, hohlen Pyramidenstumpfes oder hohlen Keilstumpfes, dessen Mantelfläche (2) aus einer abgeflachten, oberen Knochenkontaktfläche (3), einer abgeflachten, unteren Knochenkontaktfläche (4) und zwei Seitenflächen (5) besteht. Die obere und untere Knochenkontaktfläche (3; 4) ist gegen den Innenraum (6) des Hohlkörperprofils (1) elastisch komprimierbar, derart, daß der maximale Abstand H zwischen oberer und unterer Knochenkontaktfläche (3; 4) um 0,5 - 5,0 mm reduzierbar ist.
(EN) The intervertebral implant consists of a flattened shaped hollow element (1) in the form of a hollow cylinder, hollow truncated cone, hollow truncated pyramid or hollow truncated wedge, with an outer surface (2) comprising a flattened upper bone-contact face (3), a flattened lower bone-contact face (4) and two lateral faces (5). The upper and lower bone-contact faces (3, 4) can be compressed elastically towards the inner chamber (6) of the element (1) in such a way that the maximum distance H between the upper and lower bone contact faces (3, 4) can be reduced by 0.5-5.0 mm.
(FR) L'invention concerne un implant intervertébral constitué d'un corps creux (1) profilé aplati, se présentant sous forme de cylindre creux, de cône tronqué creux, de pyramide tronquée creuse ou de coin tronqué creux, dont la surface (2) extérieure comprend une face (3) de contact osseux supérieure et aplatie, une face (4) de contact osseux inférieure aplatie et deux faces (5) latérales. Les faces (3;4) de contact osseux supérieure et inférieure sont compressibles de façon élastique vers la cavité (6) du corps creux (1) profilé de façon à réduire la distance H maximale séparant les faces (3;4) de contact osseux supérieure et inférieure d'une valeur comprise entre 0,5 et 5,0 mm.
