Stabilisation device for dynamic stabilisation of vertebrae

摘要

The device has two bone anchoring elements (2, 2') for anchoring in a bone part (4), and another two bone anchoring element (3, 3') for anchoring in another bone part (5). Two rod-shaped elements (1, 1') are respectively connected to two of the four anchoring elements. A plane is defined at connection points of the anchoring and rod-shaped elements. Each rod-shaped element has a curved section (7), which elastically deforms under action of force acting on the rod-shaped elements. The rod-shaped elements are arranged so that the curved section resides within the plane or parallel to the plane.
