A device (100) for spinal stabilization includes bone anchors (110a, 110b), a metal cord (120), and a spacer (130) Each bone anchor (110a, 110b) has a clamping mechanism (150) for securing the cord (120) to the bone anchor (110a, 110b) In an assembled and implanted state of the device (100), the spacer (130) is positioned between two neighboring bone anchors (110a, 110b), thereby impeding the motion of the bone anchors toward each other, the cord (120) is clamped to the bone anchors, thereby impeding the motion of the bone anchors away from each other By increasing or decreasing the tension in the cord (120) dunng implantation, the physician can create a stabilization device (100) that is either relatively stiff or relatively flexible to accommodate the specific needs of the patient
