    摘要： The present invention provides various interspinous vertebral implants and methods for using the same for dynamic stabilization of spine. The interspinous vertebral implants of the present invention comprises a resiliently compressible body that is adapted for position between adjacent superior and inferior spinous processes, and an anchoring member that is affixed to the superior and the inferior spinous processes posterior to the resiliently compressible body. The anchoring member provides a compressive force while the resiliently compressible body provides a distraction. Without being bound by any theory, it is believed that the combination of the distraction and compressive forces created by interspinous vertebral implants of the present invention results in a rotational moment, which alleviates compression on the intervertebral disk.

    摘要： A surgical instrument system for distraction and endplate preparation of two adjacent vertebrae during a spinal stabilization procedure includes a distraction device with two arms each having two spaced-apart vertebra engaging portions at a distal end and capable of bilaterally engaging the vertebra. The system further includes a template having a guide portion and one or more spacer portions for inserting into the disc space between the two vertebrae and maintaining a predetermined distance between the vertebrae. The system further includes an endplate preparation device adapted to modify the adjacent endplates of the first and second vertebrae for receiving a spinal stabilization implant, the endplate preparation device having a range of motion that may be limited by the guide in at least one dimension.
