INTERVERTEBRAL DISC PROSTHESIS FOR STABILIZING THE LUMBAR SPINE AND RELEVANT KIT

摘要

The present invention concerns an intervertebral disc prosthesis (1 ) interposable between two vertebral bodies (A, B), characterized in that it comprises at least one upper arm (20, 20') extending essentially longitudinally, at least one lower arm (30, 30') extending essentially longitudinally, and a junction intermediate element (50), interposed between said at least one upper arm (20, 20') and said at least one lower arm (30, 30'), and rotatably coupling said arms by coupling means (60), said prosthesis (1) taking a closed operating position, in which said arms (20, 20', 30, 30') are arranged with the longitudinal axes substantially aligned, and an opened operating position, in which said arms (20, 20', 30, 30') have the axes out of alignment. The present invention also relates to an intevertebral disc prosthesis.
