Abstract:
A shackle element adapted to clamp a fixation rod essentially extending along a spine, havinga groove with a groove bottom extending in cross section along an arc of 180Â° plus a partial angle in a range between 0.5Â° and 80Â°, being intended for a longitudinally displaceable reception of the fixation rod restable on the groove bottom so that the fixation rod is enclosable by more than 180Â° in a circumferential direction thereof, two lateral walls adjoining the groove bottom, the lateral walls formed at an angle to each other with a distance between the lateral walls increasing with a growing distance from the groove bottom in order to form an entrance wide enough to introduce the fixation rod into the groove, a first one of the lateral walls being thinner than a second one of the lateral walls which is thicker than the first one of the lateral walls, a hook element of a hook protruding from the thicker wall, and a screw device for clamping the fixation rod, being designed and arranged in such a way that the lateral walls of the shackle element can be pressed toward each other after introducing the fixation rod for clamping the fixation rod.
