摘要：A dynamic fixation device is provided that allows the vertebrae to which it isattached to move in flexion within the normal physiological limits of motion, while alsoproviding structural support that limits the amount of translation motion beyond normalphysiological limits. The present invention includes a flexible portion and two ends thatare adapted for connection to pedicle screws. In at least one embodiment of the presentinvention, the normal axis of rotation of the vertebrae is substantially duplicated by thedynamic fixation device. The flexible portion of the dynamic fixation device can include aflexible anterior-posterior segment, an anterior-posterior segment bounded by one ormore zones with cuts in the rod portions, a flexible accordion-like segment, and/or ahinge portion.
