Abrégé
(EN)
The present application provides a system and method for lumbar arthroplasty in a spinal segment having first and second vertebral bodies, where a intervertebral disc prosthesis (26) may be provided and positioned between the first and second vertebral bodies such that a center of rotation of movement (34) of the vertebral bodies about the prosthesis is located substantially proximate to the upper endplate of the second vertebral body and substantially proximate to the posterior one- third portion of the second vertebral body. In addition, a stabilization (35) element may be affixed to the first and second vertebral bodies such that a range of motion of the stabilization device defines a center of rotation (36) substantially proximate to that of the intervertebral disc prosthesis.

La présente invention concerne un système et un procédé pour une arthroplastie lombaire dans un segment médullaire ayant un premier et un second corps vertébral, où une prothèse de disque intervertébral (26) peut être disposée et positionnée entre le premier et le second corps vertébral, de telle sorte qu'un centre de rotation de mouvement (34) des corps vertébraux autour de la prothèse est situé sensiblement à proximité de la plaque d'extrémité supérieure du second corps vertébral et sensiblement à proximité du premier tiers postérieure du second corps vertébral. De plus, un élément de stabilisation (35) peut être fixé au premier et au second corps vertébral, de telle sorte qu'une plage de mouvement du dispositif de stabilisation définit un centre de rotation (36) sensiblement à proximité de celui de la prothèse de disque intervertébral.
