Abstract:
1. An intervertebral disc prosthesis, comprising: first and second rigid plates each comprising an inner face and an outer face designed to be attached on one of two vertebrae adjacent to an intervertebral disc to be replaced, each of the first and second plates comprises first attaching means including two first attaching portions positioned substantially symmetrically on either side of an anteroposterior median plane of said plate, second attaching means including two second attaching portions positioned substantially symmetrically on either side of a first plane substantially perpendicular to the inner face of said plate and inclined by a first angle comprised between 50° and 70° relative to the anteroposterior median plane of said plate, and third attaching means opposite the second attaching means relative to the anteroposterior median plane and including two third attaching portions positioned substantially symmetrically on either side of a second plane substantially perpendicular to the inner face of said plate and inclined by a second angle comprised between 85° and 95° relative to the anteroposterior median plane of said plate; and a compression pad arranged between the first and second plates and secured to the inner faces of the first and second plates; wherein the first, second and third attaching means formed on the first plate are arranged to be situated respectively across from the first, second and third attaching means formed on the second plate, and the first, second and third attaching means of the first and second plates are designed to cooperate respectively with complementary attaching means mounted on a gripping member, wherein each of the first, second and third attaching portion is formed at least partially by an attaching rim delimited by a notch formed in the corresponding plate and emerging in a periphery of said plate, wherein each notch extends over a portion of a thickness of the corresponding plate and emerges in the inner face of said plate.
