Abstract
An implant for stabilizing the vertebral column, having a longitudinal support and anchoring screws which can be fastened to the latter in an angularly stable manner so that even long-span multi-segmental instabilities can be treated. As the longitudinal support a sectional rod is provided, to which transverse brackets are clamped. The anchoring screws are fastened at an adjustable angle of inclination to a transverse bracket in each case. The transverse bracket comprises a clamping piece and a connector, which are screwed together. The clamping piece has two jaws which form a suitable receiving opening for the preferably cross-sectionally circular sectional rod and are drawn together by a clamping screw. In addition, two repositioning instruments for altering the position of the vertebral bodies during the operation are described, namely a traction instrument and an instrument which can be used as a basis of application for the traction instrument and which creates a connection between two neutral vertebrae.
