Abstract
Dynamic posterior stabilization systems and methods of stabilizing vertebrae are described. A dynamic posterior stabilization system may include bone fasteners and a dampener system. The bone fasteners may be secured to the vertebrae, and the dampener system may be attached to the bone fasteners. The dampener system may include a first dampener set and a second dampener set positioned on an elongated member. The first dampener set may be compressed and provides resistance to movement of the first bone fastener towards the second bone fastener. The second dampener set may be compressed and provide resistance to movement of the first bone fastener away from the second bone fastener.
