Abstract: A spinal stabilization device allowing motion between adjacent vertebrae is provided. The spinal stabilization device connects at least two adjacent vertebrae using an elongated block operatively connected or compressed between the heads of two screws connected to the adjacent vertebrae. The head and the screw may be separate such that they may be componible together. A resilient tie-member is connected between two heads to keep the block in position. The tie-member is in tension to maintain the elongated block compressed. The spinal stabilization device may have a transversal tie-member that connects between the heads of two screws transverse and diagonal with respect to the spinal column.
