Abstract
Various methods and devices for replacing damaged, injured, diseased, or otherwise unhealthy posterior elements, such as the facet joints, the lamina, the posterior ligaments, and/or other features of a patient's spinal column, are provided. In certain exemplary embodiments, a four bar linkage mechanism can be used to construct spinal stabilization devices and methods for restoring function to adjacent vertebrae. In particular, spinal stabilization devices can be provided that kinematically form a four-bar linkage mechanism with adjacent vertebrae and a disc or other element disposed between the adjacent vertebrae.
