摘要：
Dynamic posterior stabilization systems and methods of stabilizing vertebrae are described. A dynamic posterior stabilization system may include a first bone fastener configured to couple to a first vertebra, a second bone fastener configured to couple to a second vertebra, and a dampener system attached to the first bone fastener and the second bone fastener. The dampener system may include a single dampener set. Compression of the single dampener set provides resistance to movement of the first bone fastener towards the second bone fastener. Compression of the first dampener set and the second dampener set provides resistance to movement of the first bone fastener away from the second bone fastener.
