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.
