Abstract
A stabilization system for a human spine is provided. The stabilization system may include one or more dynamic interbody devices and/or one or more dynamic posterior stabilization systems. The dynamic interbody devices may allow for coupled axial rotation and lateral bending of vertebrae adjacent to the dynamic interbody devices. In an embodiment, the dynamic interbody device includes a keel having a neck and a cylindrical base. The cylindrical base is wider than the neck. In an embodiment, portions of the dynamic interbody device that allow for flexion and/or extension of vertebra coupled to the dynamic interbody device are coupled together by ball bearings.
