摘要：
Intervertebral disc prosthesis comprising at least three parts that include a first plate, called the upper plate (1), a second plate, called the lower plate (2), and a core (3), the upper surface of the core being ( 3) in contact with at least part (10) of the lower surface of the upper plate (1) and the lower surface of the core (3) being in contact with at least part of the upper surface of the lower plate (2), and the upper plate (1) being mobile at least with respect to the core (3), the prosthesis also comprises means of cooperation between the lower plate (2) and the core (3), to allow limited movement movements of the core (3 ) with respect to the lower plate (2) along an axis substantially parallel to the lower plate (2), and to allow limited rotational movements of the core (3) with respect to the lower plate (2), around an axis substantially perpendicular to the bottom plate ( 2), characterized in that said cooperation means comprise: - male means located opposite each other near edges of the bottom plate (2) and formed by two pins, or a pin and a dowel, or two dowels, or two walls in cooperation with - female means formed by two recesses (30) at the edges of the core (3) and complementary to said pins, studs or walls.Prótesis de disco intervertebral que comprende al menos tres partes que incluyen una primera placa, denominada la placa superior (1), una segunda placa, denominada la placa inferior (2), y un núcleo (3), estando la superficie superior del núcleo (3) en contacto con al menos parte (10) de la superficie inferior de la placa superior (1) y estando la superficie inferior del núcleo (3) en contacto con al menos parte de la superficie superior de la placa inferior (2), y siendo la placa superior (1) móvil al menos con respecto al núcleo (3), la prótesis también comprende medios de cooperación entre la placa inferior (2) y el núcleo (3), para permitir movimientos de traslación limitados del núcleo (3) con respecto a la placa inferior (2) a lo largo
