Abstract:
A stabilization device includes a first bone anchoring element, a second bone anchoring element, and a rod-shaped element for connecting the first and the second bone anchoring elements. The rod-shaped element includes a curved section, that undergoes an elastic deformation under the action of a force acting on the rod-shaped element via an anchoring element. The rod-shaped element and the anchoring elements are arranged so that deformation occurs when a force acts in a main direction of motion of bone parts or vertebra relative to each other, whereas a deformation is suppressed when a force acts in a direction that is essentially perpendicular to the main direction of motion.
