Abstract
Dynamic posterior stabilization systems are described. A dynamic posterior stabilization system may include bone fasteners and a dampener system. The dampener system may include a first elongated member and a second elongated member that couple together to form a variable length elongated member. The dampener system may also include one or more dampener sets. The dampener sets may provide resistance to movement of vertebrae coupled to the dynamic posterior stabilization system.
