A stabilization system for a human spine is provided. The stabilization
system may include two dynamic interbody devices and/or one or more
dynamic posterior stabilization systems. The dynamic interbody devices
may be inserted into a disc space using a posterior approach. The dynamic
interbody devices may allow for coupled axial rotation and lateral
bending of vertebrae adjacent to the dynamic interbody devices. The
dynamic posterior stabilization systems may provide resistance to
movement that mimics the resistance provided by a normal functional
spinal unit.
