Abstract

Various methods and devices are provided for stabilizing the posterior elements of the spine, and more preferably methods and devices are provided for sharing the load with the intervertebral disc, the facet joints, the ligaments, and the muscles of the spinal column. In certain exemplary embodiments, methods and devices are provided for substantially controlling or providing resistance to movement, e.g., flexion, extension, lateral bending, and/or axial rotation, of the adjacent vertebrae.
