ABSTRACT:
A vertebral column support device is assembled by means of clamping. The device includes bone screw- or hook-type vertebrae anchoring elements, the elements consisting of a threaded cylindrical part (5) and a stop collar (7). A fixing nut (8) can be screwed on the threaded cylindrical part (5) in order to fix a connecting sliding piece (4) which is mounted on a securing rod (3) having a circular section. In order to insure that the rod (3) and the connecting sliding piece (4) are secure, the securing rod (3) is clamped in a transverse groove (17) in the connecting sliding piece (4) using a clamp screw (21) and a little clamp (22) which is mounted in the corner of the groove. In this way, the inventive device is more rigid and can better support the vertebrae and, moreover, the device can be positioned and adjusted much more easily.
