Abstract
A configurable dynamic spinal rod for connecting levels of a dynamic stabilization system to support the spine while providing for the preservation of spinal motion. Embodiments of the dynamic stabilization system have an anchor system, a deflection system, a vertical rod system and a connection system. The deflection system provides dynamic stabilization and load-sharing. The dynamic spinal rod connects different levels of the construct in a multilevel construct. The dynamic spinal rod cooperates with the deflection system to further reduce stress exerted upon the bone anchors and spinal anatomy. A configurable lock is provided which can selectably lock an angle between the dynamic spinal rod and a dynamic bone anchor.
