Abstract

An intervertebral implant with a central axis, a top part, a bottom part, a joint comprising a joint part and a joint shell, and a joining means. The top part has a top apposed surface that is suitable for placing it on a vertebra situated above it; The bottom part has a bottom apposed surface, that is suitable for placing it on a vertebra situated below it. One of the two parts is operatively associated with a convex joint part and the other part to a matching joint shell. The joint part and the joint shell are mounted against one another in a sliding manner such that the top part and the bottom part can rotate relative to one another at least about one axis of rotation. The joining means holds the top part and the bottom part together without impairing the capability of the joint to pivot while allowing a clearance between the joint part and the joint shell.

Claims (24)

1. An intervertebral implant (1) in particular an artificial intervertebral disk, with a central axis (2), a top part (3) and a bottom part (4), wherein A) the top part (3) has a top apposition surface (5), that is suitable for placing it on the base plate of a body of the vertebra situated above it;
B) the bottom part (4) has a bottom apposition surface (6), that is suitable for placing it on the cover plate of a body of the vertebra situated below it;
