Abstract

Embodiments herein are generally directed to spinal implants for use in orthopedic stabilization assemblies. In some embodiments, these implants may be used in conjunction with laminoplasty or laminectomy procedures.

First claim

I claim:

1. A spinal implant assembly comprising:
a superior translateral stabilization system comprising a first facet stabilization device and a first translateral plate, wherein the superior translateral stabilization system comprises a first U-shaped channel extending therefrom;
an inferior translateral stabilization system comprising a second facet stabilization device and a second translateral plate, wherein the inferior translateral stabilization system comprises a second U-shaped channel extending therefrom; and
a rod member, wherein the rod member is downwardly deposited into the first U-shaped channel and the second U-shaped channel such that it extends between the superior translateral stabilization system and the inferior translateral stabilization system,
wherein the first U-shaped channel is configured to articulate relative to the first translateral plate, wherein the U-shaped channel is formed on top of an articulatable platform having a top surface and bottom surface, wherein the platform forms a ball and socket joint with the first translateral plate.

2. The spinal implant of claim 1 , wherein the first translateral plate comprises:
a first fixation section configured to engage a first bone structure;
a second fixation section configured to engage a second bone structure; and
a middle section disposed between the first and second fixation sections.

3. The spinal implant of claim 2 , wherein the first U-shaped channel extends from the middle section of the first translateral plate.

4. The spinal implant of claim 3 , wherein the first U-shaped channel includes an interiorly-threaded upper section.

5. The spinal implant of claim 4 , wherein the first U-shaped channel has a longitudinal axis that is orthogonal to a transverse axis of the first translateral plate.

6. The spinal implant of claim 3 , wherein the middle section of the first translateral plate further comprises a top surface having a convex protrusion thereon.

7. The spinal implant of claim 6 , wherein the superior translateral stabilization system comprises a platform having a top surface and a bottom surface, wherein:
the top surface comprises two arms extending therefrom and defining the first U-shaped channel; and
the bottom surface comprises a concave depression configured to receive the convex protrusion of the first translateral plate.

8. The spinal implant of claim 2 , wherein the first fixation section comprises a first hole passing through from a top surface to a bottom surface, and the second fixation section comprises a second hole passing through from a top surface to a bottom surface.

9. The spinal implant assembly of claim 1 , wherein the first facet stabilization device comprises:
a left inferior facet joint prosthesis;
a left superior facet joint prosthesis;
a right inferior facet joint prosthesis; and
a right superior facet joint prosthesis.

10. The spinal implant of claim 1 , wherein the superior translateral stabilization system comprises a first fixation section, a second fixation section, and a middle section elevated above the first fixation section and the second fixation section.

11. The spinal implant of claim 1 , wherein the superior translateral stabilization system comprises a first fixation section, a second fixation section and an elevated middle section, wherein the first U-shaped channel extends from the elevated middle section.

12. The spinal implant of claim 1 , wherein the second U-shaped channel is configured to articulate relative to the second translateral plate.

13. A spinal implant assembly comprising:
a superior translateral stabilization system comprising a first translateral plate, wherein the first translateral plate comprises a first fixation section, a second fixation section and a middle section elevated above the first fixation section and the second fixation section, wherein the superior translateral stabilization system comprises a first U-shaped channel extending therefrom;
an inferior translateral stabilization system comprising a second translateral plate, wherein the inferior translateral stabilization system comprises a second U-shaped channel extending therefrom; and
a rod member, wherein the rod member is downwardly deposited into the first U-shaped channel and the second U-shaped channel such that it extends between the superior translateral stabilization system and the inferior translateral stabilization system,
wherein the first U-shaped channel is configured to articulate relative to the first translateral plate, wherein the U-shaped channel is formed on top of an articulatable platform having a top surface and bottom surface, wherein the platform forms a ball and socket joint with the first translateral plate.

14. The spinal implant of claim 13 , wherein the secondary stabilization system comprises first and second connecting plates.

15. The spinal implant of claim 14 , wherein the secondary stabilization system further comprises a prosthetic spinous process.

16. The spinal implant of claim 13 , wherein the secondary stabilization system comprises a dynamic stabilizer.

17. The spinal implant of claim 13 , wherein the secondary stabilization system comprises a flexible rod.

18. The spinal implant of claim 13 , wherein the secondary stabilization system comprises a rigid rod made of a material selected from the group consisting of titanium and PEEK.

19. The spinal implant of claim 13 , wherein the first U-shaped channel extends from the elevated middle section.

20. The spinal implant of claim 13 , wherein the first translateral plate includes first and second side rails extending along the middle section and configured to maintain engagement between the first U-shaped channel and the middle section.
