摘要： A rod-shaped element for use in spinal or trauma surgery, having a first section for connecting to a first bone anchoring element and a second section for connecting to a second bone anchoring element is described. The rod-shaped element also includes a first elastic flexible element that is capable of elastic deformation when a force acts on it transverse to the rod axis. The first section and the second section are capable of shifting relative to each other in the direction of the rod axis. In a stabilization device for use in spinal or trauma surgery, the rod-shaped element allows for a controlled motion of the parts to be stabilized relative to each other so flexural motion is adjusted separately from the adjustment of the mobility in axial direction.
