Abstract

The present application generally relates to orthopedic systems, and in particular, to systems including independent plates and spacers. A plating system can include a spacer and a plate that is independent from the spacer. A number of locking mechanisms can be provided to secure the plate to the spacer. In some cases, the spacer includes a pair of notches that extend on an outer surface of the spacer. The plate can include a pair of lateral extensions that can engage the notches to secure the plate to the spacer. In other cases, the spacer includes an opening including a pair of inlets. The plate can include an enclosed posterior extension that can be received in the pair of inlets to secure the plate to the spacer.

First claim

What is claimed is:

1. A system for use in a spinal surgery comprising:
a plate spacer assembly comprising:
a plate; and
a spacer, wherein the spacer comprises a body having an upper surface for contacting an upper vertebral body and a lower surface for contacting a lower vertebral body; and
an implant assembly press for assembling the plate to the spacer comprising:
an upper press; and
a lower press,
wherein the lower press is configured to receive the spacer,
wherein the lower press is configured to receive the plate,
wherein the upper press is configured to apply a downward force on the plate to slideably secure the plate to the spacer,
wherein in a first position the upper press and the lower press are not engaged and in a second position the upper press and lower press engage with each other, and
wherein the lower press comprises a spacer track for receiving at least one spacer and the lower press comprises a plate track for receiving at least one plate, the spacer track being different than the plate track.

2. The system of claim 1 , wherein the upper press comprises a top plate and one or more extensions extending downwardly therefrom.

3. The system of claim 2 , wherein the upper press comprises four extensions.

4. The system of claim 1 , wherein the spacer track is horizontally offset from the plate track.

5. The system of claim 1 , wherein the plate track has a height greater than the spacer track.

6. The system of claim 1 , wherein the plate comprises a delrin plate.

7. The system of claim 1 , wherein the spacer is formed of PEEK or allograft.

8. The system of claim 1 , wherein the plate comprises a pair of extension arms that extend around sides of the spacer.

9. The system of claim 8 , wherein the pair of extension arms each include a window for receiving a corresponding bump out portion on each of the sides of the spacer.

10. A system for use in a spinal surgery comprising:
a plate spacer assembly comprising:
a plate; and
a spacer, wherein the spacer is formed of either allograft or PEEK; and
an implant assembly press for assembling the plate to the spacer comprising:
an upper press; and
a lower press,
wherein the lower press is configured to receive the spacer,
wherein the lower press is configured to receive the plate,
wherein the upper press is configured to apply a downward force on the plate to slideably secure the plate to the spacer,
wherein in a first position the upper press and the lower press are not engaged and in a second position the upper press and lower press engage with each other, and
wherein the lower press comprises a spacer track for receiving a spacer and the lower press comprises a plate track for receiving a plate, the spacer track being different than the plate track.

11. The system of claim 10 , wherein the upper press comprises one or more downward extensions.

12. The system of claim 11 , wherein the one or more downward extensions include one or more teeth.

13. The system of claim 12 , wherein the one or more teeth are configured to contact an upper surface of the plate to secure the plate to the spacer.

14. The system of claim 10 , wherein the plate comprises a pair of extension arms for receiving the spacer therein.

15. The system of claim 14 , wherein at least one of the extension arms includes a window.

16. The system of claim 15 , wherein the spacer includes a bump out portion, wherein the bump out portion is received in the window.

17. The system of claim 10 , wherein the spacer track is horizontally offset from the plate track.

18. The system of claim 10 , wherein the plate track has a height greater than the spacer track.
