摘要
A dynamic spinal stabilization device for the treatment of high-grade spinal disorders is disclosed herein. The dynamic spinal stabilization device includes two or more screw assemblies, each of which include a pedicle screw and a head socket containing a curved internal track that limits the range of motion and center of rotation of the spinal segments stabilized using the device to the physiological levels of a nondegraded spinal segment.
