Abstract
A dynamic posterior stabilization system is provided to stabilize a human spine. In some embodiments, the dynamic posterior stabilization system includes a first bone fastener, a second bone fastener, and an elongated member coupled to the first bone fastener and the second bone fastener. The longitudinal position of the elongated member relative to the first bone fastener may be fixed. The longitudinal position of the second bone fastener relative to the elongated member may vary so that the dynamic posterior stabilization system can accommodate flexion/extension and/or lateral bending. The dynamic posterior stabilization system may also be able to accommodate axial rotation. Bias members may be coupled to the elongated member. The bias members may allow the dynamic posterior stabilization system to mimic the resistance behavior of a normal functional spinal unit.
