Abstract
The present invention provides a pedicle screw-based dynamic posterior stabilization system that is used to stabilize the segments of the cervical, thoracic, lumbar, and sacral spine as an adjunct to, or in place of, conventional spinal fusion using bone grafts. The system includes a plurality of pedicle screws, each of the plurality of pedicle screws including a head portion, and the head portion of each of the plurality of pedicle screws forming a first half of a joint that allows relative pivoting movement about the head portion of each of the plurality of pedicle screws and up-and-down movement with respect to the head portion of each of the plurality of pedicle screws. The system also includes a stabilization body coupled to the plurality of pedicle screws, the stabilization body including a plurality of end portions, and the end portions of the stabilization body forming a plurality of second halves of the joints formed by the head portion of each of the plurality of pedicle screws.
