摘要

Intervertebral Implant (1), in particular artificial intervertebral disc with a Central Axis (2), (3) an upper part, a lower part (4); in which: a).- the upper part (3) has a higher area of apposition (5), which is suitable for its support on the base plate of a vertebral Body located above the Mass; (b).- The Bottom (4) presents a Lower area of apposition (6), which is adequate to support the cover plate of a vertebral Body located below it; (c).- one of the two Parties (3; 4) comprises a convex part (12) of the Joint with a First area of the Joint,And the other of the two sides (3; 4) includes a Body (13) of the Joint podez slide on the way; and (d).The Convex part (12) of the joint and the Body (13) of the joint form a joint (9) through which the two Parties (3; 4) can rotate with respect to one another toAround at least one Axis of rotation; and (e).- one of the Parties (3; 4) covers at least a binding medium (20) in which the two parties are held (3; 4) assembled together,Without the adjustability of the affected Joint (9); and (f).- the means of Union (20) in any position of the articularcion (9) allows a greater than 0 x axial play between the two sides (3; 4).
