FIELD: medicine.
SUBSTANCE: six-step intervertebral disc endoprothesis contains upper and lower axisymmetric and opposite supporting plates with serrated fixation elements in the bodies of the vertebrae on plates outer surfaces and elastic supporting-centering elements installed between the plates. The supporting-centering elements are made as single-coil screw cylindrical springs of various diameters installed concentrically coaxially to the plates, the ends of turns are bent in the axial direction and fixed in the holes formed in the supporting plates, located at the same angular distances from each other. The turns of each pair of springs have the opposite angle of inclination.
EFFECT: simplified installation of the endoprosthesis in the intervertebral space, prolongation of service life.
