Abstract: This specification describes spinal stabilization devices that may be introduced into the spine via surgical procedures. In particular, this specification describes an inter-spinous process spacer having a core chosen, in one variation, to provide a kyphotic or lordotic angle to the device. The specification also describes systems including the described devices and methods of introducing the devices and systems into the spine to provide effective stabilization.

Abstract: Spinal stabilization devices, systems, and methods are described. Foramenal spacers including a rigid member adapted to maintain the integrity of the foramenal space. Facet joint stabilizing members and prosthetic facet joints that augment or replace the native facet joint are also described. Lateral spinal stabilization systems that may be attached to the lateral surfaces of adjacent vertebral bodies are described. Also described are anterior spinal stabilization systems that are to be attached to the anterior surfaces of adjacent vertebral bodies. Several variations of dynamic spinal stabilization devices and systems are described. Each of the foregoing devices, systems, and methods may be used independently, in combination with the other devices, systems, and methods described herein, and/or in combination with prosthetic intervertebral discs.

Abstract: A prosthetic intervertebral disc and methods for using the same are provided. The subject prosthetic discs are characterized by including top and bottom endplates separated by a fibrous compressible element that includes an annular region and a nuclear region. The two plates are held together at least one fiber wound around at least one region of the top endplate and at least one region of the bottom endplate. The subject discs may he employed with separate vertebral body fixation elements, or they may include integrated vertebral body fixation elements. Also provided are kits and systems that include the subject prosthetic discs.

Abstract: Prosthetic intervertebral discs and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The prosthetic discs described herein include one-piece, two-piece, three-piece, and four-piece structures. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the sagittal plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components of the discs. The interface mechanism between the endplates and the core members of several embodiments of the described prosthetic discs enables a very easy surgical operation for implantation.

Abstract: We describe various alignable tools, in particular, trials and chisels, that may be used in preparing an intervertebral site in a spine, the site being suitable for placement of a prosthetic intervertebral disc as a replacement for a natural disc in that spine. We also describe methods of using those tools.
