Abstract

A stabilization system for a human spine is provided comprising at least two dynamic interbody devices (50', 50' ') and at least one dynamic posterior stabilization system (118). In some embodiments the stabilization system comprises a pair of dynamic interbody devices and a pair of dynamic posterior stabilization systems. The dynamic interbody devices may work in conjunction with the dynamic posterior stabilization systems to allow for movement of vertebrae coupled to the stabilization system. The dynamic posterior stabilization systems may provide resistance to movement that mimics the resistance provided by a normal functional spinal unit. In some embodiments, a bridge (70) may couple a dynamic interbody device to a dynamic posterior stabilization system.
