An intervertebral disk prosthesis includes a first anchoring device for
anchoring the prosthesis to a first vertebral body and a second anchoring
device for anchoring the prostheses to a second vertebral body. The two
anchoring devices are moveably coupled to each other. The coupling
between the two anchoring devices may include at least one deformable
element. The coupling may be constructed as a single piece integrally
with the first anchoring device and/or with the second anchoring device.
