    摘要: A vertebral column implant for stabilizing and stiffening of vertebral bodies of a vertebral column comprises at least one first and at least one second bone screw, which is screwable into a vertebral body. A first rigid connecting element is insertable into first receiving means of the first bone screw. A second elastic connecting element is insertable into second receiving means of the second bone screw. The connecting means are installed on a further bone screw and comprise a first and second clamping device for respectively holding tightly the first and second connecting element. The first clamping device has a U-shaped receiving part for the end region of the first connecting element, which is designed spherical, a clamping means being placeable on the U-shaped receiving part, with which clamping means the spherical end region is able to be clamped against the bottom surface of the U-shaped receiving part.

    摘要: An intervertebral stabilization device and method is disclosed. The device preferably includes a planar spring enclosed within a housing. The housing is joined to an articulation component at either end, and the articulation components have couplings connectable to anchoring components which are securable to adjacent vertebrae. The planar spring can flex and retract providing relative motion between the adjacent vertebrae. The articulation components are ball and socket joints which allow the entire assembly to flexibly follow the curvature of the spine. A fusion rod with articulation components and couplings at either end may be substituted for the spring device. The couplings enable interchangeability between a fusion rod assembly and spring assembly, so that dynamic stabilization can occur at one vertebral level and fusion at the adjacent vertebral level. An overhung spring assembly with a sideways displaced housing which allows for a shorter pedicle to pedicle displacement is also disclosed.
