Abstract
An intervertebral disk prosthesis is described which with respect to its external dimensions imitates a natural intervertebral disk and connects two adjacent vertebrae to their upper and lower attachment surfaces. The intervertebral disk member is made of one piece from a strong, elastically deformable material and comprises parallel slits at a right angle to the connecting axis which partially overlap. In overlapping regions adjacent slits form parts of leaf springs for the transmission of forces from one attachment surface of the prosthesis to the other attachment surface.
