Universal laminoplasty implant

1. A method comprising:

performing a laminoplasty procedure;

providing a bone fixation device; wherein the bone fixation device comprises at least one longitudinal plate with a proximal end and a distal end, the plate is adapted to be configured so that at least one end engages a portion of a lamina, the plate including a hollow rectangular portion with a partially hollow top wall, a solid bottom wall, lamina engaging hollow end walls, at least one side wall having recesses, and a spacer portion having side wall teeth, wherein the hollow rectangular portion and the spacer portion are telescopically engaged to each other with the side wall recesses and the side wall teeth; the hollow rectangular portion is moveable between a retracted position and an extended position to accommodate a length of a lamina displacement.

2. The method of claim 1 , further comprising: a plurality of hollow engaging portions, which includes overlapped slidably engaging portions allowing the least one longitudinal plate to move between the retracted and extended positions.

3. The method of claim 1 , wherein the plate further including plurality of apertures adapted to receive fasteners to fasten at least a portion of the plate to at least a portion of the lamina.

4. The method of claim 2 , wherein the plurality of hollow engaging portions is adapted to receive bone fusion materials, which includes autograft bone, allograft bone, xenograft bone, bone morphogenic protein, and hydroxypatic.

5. The method of claim 1 wherein the plate further including an engaging mechanism to stabilize the plate after implementation.

6. The method of claim 1 wherein the distal end and the proximal end of the plate are configured to engage a portion of the lamina.

7. The method of claim 1 wherein the top wall is configured to receive bone fusion materials.

8. The method of claim 1 wherein each of the proximal and distal ends of the plate are contoured to engage a portion of the lamina to hold and stabilize the lamina.

9. The method of claim 1 wherein the plate includes at least one adjustable energy storing mechanism to enable the device to move between the retracted and extended positions and stabilize the device after implantation.

10. The method of claim 1 wherein each proximal and distal ends further include at least one extension attachable to a portion of the lamina.

11. The method of claim 10 wherein each end is configured to receive at least one fastener to fasten the end to a portion of the lamina.

12. The method of claim 10 wherein the extension is arcuately extending to attach to a portion of the lamina.

13. A method comprising:

performing a laminoplasty procedure;

providing a bone fixation device; wherein the bone fixation device comprises at least one longitudinal plate with a proximal end and a distal end, the at least one longitudinal plate is adapted so that each of the proximal end and the distal end engages a portion of a lamina, the at least one longitudinal plate includes a couple of slidably engaging portions allowing the at least one longitudinal plate to move between a retracted position and an extended positions to accommodate the length of the displaced lamina, and wherein one of the engaging portions is a hollow rectangular portion, is adapted to receive bone fusion materials, and includes a hollow end wall for engaging the lamina and one side wall having recesses, and wherein the other engaging portion includes a hollow end wall for engaging the lamina and a side wall with teeth for telescopic engagement with the side wall recesses, and wherein the at least one longitudinal plate is configured to attach to any portions of a lamina along the longitudinal axis of the at least one longitudinal plate.

14. The method of claim 13 wherein the plate further includes plurality of apertures adapted to receive fasteners to fasten portion of the plate to portions of the lamina.

15. The method of claim 13 wherein the bone fusion material includes autograft bone, allograft bone, xenograft bone, bone morphogenic protein, and hydroxypatic.

16. The method of claim 13 wherein the plate further includes an engaging mechanism to stabilize the plate after implementation.

17. The method of claim 13 wherein the distal end and the proximal end of the plate are adapted to engage a portion of the lamina.

18. The method of claim 13 wherein the top wall is configured to receive bone fusion material.

19. The method of claim 13 wherein each of the proximal end and the distal ends is contoured to engage a portion of the lamina to hold and stabilize the lamina.

20. The method of claim 13 wherein the couple of slidably engaging portions are telescopically coupled to allow expansion and retraction.
