Abstract

Lamina plate assemblies, systems, and methods thereof. A lamina plate assembly may be configured to provide lamina support following laminectomy, for example, in cervical and lumbar cases. The lamina plate assembly may include a generally elongate body having a first free end, a second free end, and a posterior portion disposed between the first free end and the second free end. Different embodiments of securing portions are used to secure the lamina plate assembly to a vertebra.

Claims

1. A spinal system comprising:

a lamina plate assembly comprising;

a first plate member comprising a first foot, a first intermediate portion and a first hinge portion; and

a second plate member comprising a second foot, a second intermediate portion and a second hinge portion,

wherein the first hinge portion and the second hinge portion are in engagement with one another to create a hinge that adjusts the width and/or height of the lamina plate assembly, and

wherein the hinge portion includes an opening that is capable of receiving an attachment element.

2. The spinal system of claim 1, wherein the first foot includes a first kickstand.

3. The spinal system of claim 1, wherein the first foot comprises a pair of openings.

4. The spinal system of claim 3, wherein the pair of openings are in series with one another.

5. The spinal system of claim 1, wherein the first intermediate portion comprises at least one elongated opening.

6. The spinal system of claim 1, wherein the first hinge portion and the second hinge portion comprise a cylinder for receiving a pin therein and wherein the pin includes a throughbore.

7. The spinal system of claim 6, wherein the pin is engaged with the second hinge portion to form a hinge pin.

8. The spinal system of claim 1, wherein the lamina plate assembly further comprises a first removable spacer that can be slid onto the first plate member.

9. The spinal system of claim 8, wherein the removable spacer comprises a pair of sidewalls and a base.

10. The spinal system of claim 9, wherein the first intermediate portion comprises a window, wherein when the removable spacer is attached to the first plate member its base opposes the window of the first intermediate portion.

11. A spinal system comprising:

a first lamina plate assembly comprising;

a first plate member comprising a first foot, a first intermediate portion and a first hinge portion having a first opening;

a second plate member comprising a second foot, a second intermediate portion and a second hinge portion having a second opening; and

a pin member

wherein the first hinge portion and the second hinge portion are in engagement with one another such that the first opening and the second opening align to create a through bore that receives the pin member creating a hinge that adjusts the width and/or height of the lamina plate assembly, and

wherein the pin member includes a throughbore capable of receiving an attachment member.

12. The spinal system of claim 11, wherein the first foot is positioned adjacent a first kickstand.

13. The spinal system of claim 11, wherein the first foot comprises a pair of openings.

14. The spinal system of claim 13, wherein the pair of openings are in series with one another.

15. The spinal system of claim 11, wherein the first intermediate portion comprises at least one elongated opening.

16. The spinal system of claim 11, wherein the through bore has a stepped diameter.

17. The spinal system of claim 16, wherein the pin is engaged with the first and second hinge portions to form a hinge pin.

18. The spinal system of claim 11, wherein the lamina plate assembly further comprises a first removable spacer that can be slid onto the first plate member.

19. The spinal system of claim 18, wherein the removable spacer comprises a pair of sidewalls and a base.

20. The spinal system of claim 19, wherein the first intermediate portion comprises a window, wherein when the removable spacer is attached to the first plate member its base opposes the window of the first intermediate portion.
