Title (EN) IMPLANTABLE JOINT PROSTHESIS
(FR) PROTHESE D'ARTICULATION IMPLANTABLE
Abstract:
(EN) The invention relates to a surgical implant that provides an artificial diarthroidal-like joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells (20, 40), each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough that large frictional forces strongly resist any slippage between the outer surface and the bone surfaces in the joint. They may be convex, and when inserted into a milled concavity, are immediately mechanically stable.
(FR) La présente invention concerne un implant chirurgical qui permet de mettre en place une articulation artificielle de type diarthroïde, pouvant être utilisée pour remplacer toute articulation, et pouvant être utilisée en particulier en tant qu'endoprothèse discale. L'invention comprend deux coques rigides opposées ayant chacune une surface extérieure conçue pour s'accoupler avec les surfaces osseuses d'une articulation de sorte que les coques se trouvent immobilisées par frottement entre leur surfaces extérieures et les surfaces osseuses. Ces surfaces extérieures sont suffisamment rugueuses pour permettre à des forces de frottement importantes d'empêcher fortement tout glissement entre les surfaces extérieures et les surfaces osseuses de l'articulation. Elles peuvent être convexes, et, lorsqu'elles sont insérées dans une concavité meulée, elles sont immédiatement mécaniquement stables. Comme souhaité, les surfaces extérieures des coques sont conçues pour permettre l'interposition osseuse, ce qui permet de rendre les coques encore plus stables à leur emplacement. Les surfaces intérieures des coques sont relativement lisses, et sont conçues pour glisser assez facilement contre une partie de la surface extérieure d'un corps central disposé entre les coques. Le corps central a une forme qui coopère avec la forme de la surface intérieure d'une coque de manière à permettre une gamme de mouvements similaires à ceux réalisés avec une articulation saine. Une gaine flexible s'étend entre les bords des coques opposées. La surface intérieure de cette gaine, avec les surfaces intérieures des coques rigides, définit une cavité qui englobe le corps central. Au moins une partie de cette cavité est remplie d'un liquide lubrifiant permettant de réduire encore les forces de frottement entre les surfaces intérieures de la coquille et la surface du corps central.
