Abstract

A stabilizer for receiving an end of a spinal implant. The stabilizer includes a gap that creates a socket for receiving the spinal implant. Bodies of the stabilizer are manufactured in a plurality of shapes. A cover is capable of blocking egress of the spinal implant from the socket.

Claims (47)

1. A stabilizer assisting stabilization of a spinal cage implanted into a surgically created cavity; said stabilizer comprising:

a) a body distinct from said spinal cage; said body comprising:

i) a generally linear tunnel including a lengthwise axis, wherein said lengthwise axis runs in a similar direction with a longitudinal axis of said spinal cage;

ii) a first end proximate a closest lengthwise edge of said spinal cage and a second end distal from said closet lengthwise edge;

iii) a gap in said first end allowing lateral ingress and lateral egress of said closest lengthwise edge of said spinal cage such that a combination of said gap and said tunnel creates a socket securing a closest lengthwise edge of said spinal cage; and

iv) an extension comprising a plurality of apertures and integral with said body, wherein said extension is opposed to and coplanar with said gap and extends beyond said second end in a direction analogous to said lengthwise axis;

b) a cover comprising an aperture aligning with one of said extension's apertures and attachable to said extension, wherein said attached cover:

i) blocks egress from a majority of said extension's apertures; and

ii) blocks lateral egress of said spinal cage from said gap of said socket; and

c) fasteners securing said cover to said extension and said extension to vertebra.

2. The stabilizer of claim 1 , wherein said tunnel comprises a polygonal wall.

3. The stabilizer of claim 2 , wherein said polygonal wall is rectangular.

4. The stabilizer of claim 3 further comprising an amorphous segment.

5. The stabilizer of claim 2 , wherein said polygonal wall is trapezoidal.

6. The stabilizer of claim 5 further comprising an amorphous segment.

7. The stabilizer of claim 2 , wherein said polygonal wall is hexagonal.

8. The stabilizer of claim 7 further comprising an amorphous segment.

9. The stabilizer of claim 2 , wherein said tunnel further comprises a closed end proximate said extension.

10. The stabilizer of claim 1 , wherein said tunnel comprises a cylindrical wall or an elliptic cylindrical wall.

11. The stabilizer of claim 10 , wherein said cylindrical or an elliptic cylindrical wall further comprises an amorphous segment.

12. The stabilizer of claim 11 , wherein said tunnel further comprises a closed end proximate said extension.

13. The stabilizer of claim 10 , wherein said tunnel further comprises a closed end proximate said extension.

14. A stabilizer assisting stabilization of a load-bearing spinal implant implanted into a surgically created cavity; said stabilizer comprising a body distinct from said load-bearing spinal implant; said body further comprising:

a) a wall surrounding a lumen, wherein said wall further comprises:

i) first and second opposed lengthwise ends comprising openings corresponding to said lumen;

ii) a rim distal from a closest longitudinal end of said load-bearing spinal implant;

iii) a gap at said lengthwise ends proximate said load-bearing spinal implant allowing lateral ingress and egress of said closest longitudinal end of said load-bearing spinal implant, wherein a combination of said gap and said wall creates a socket securing said closest longitudinal end of said load-bearing spinal implant; and

iv) an extension comprising a plurality of apertures, wherein said extension is opposed to said gap and extends beyond said rim distal from said closest longitudinal end of said load-bearing spinal implant in a direction similar to said lengthwise axis;

b) a cover comprising an aperture aligning with one of said extension's apertures and attachable to said extension, wherein said attached cover:

i) blocks egress from a majority of said extension's apertures; and

ii) blocks lateral egress of said load-bearing spinal implant from said gap of said socket; and

c) fasteners securing said cover to said extension and said extension to vertebra.

15. The stabilizer of claim 14 , wherein said extension is coplanar with said gap.

16. The stabilizer of claim 15 , wherein said wall is a cylindrical or an elliptic cylindrical wall.

17. The stabilizer of claim 16 , wherein said cylindrical or said elliptic cylindrical wall further comprises a closed end.

18. The stabilizer of claim 16 , wherein said cylindrical or an elliptic cylindrical wall further comprises an amorphous segment.

19. A stabilizer for assisting stabilization of a spinal cage implanted into a surgically created cavity, wherein said stabilizer is distinct from said spinal cage; said stabilizer comprising:

a) a cylindrical or an elliptic cylindrical wall encircling a lumen, wherein said wall comprises a first lengthwise end, a second lengthwise end and a lengthwise axis; said wall further comprising:

i) a rim at said first lengthwise end, wherein said rim is distal from a closest longitudinal end of said spinal cage;

ii) an opening opposite said rim surrounding said closest longitudinal end of said spinal cage;

iii) a gap at said second lengthwise end opposite said first lengthwise end allowing lateral ingress and lateral egress of said closest longitudinal end of said spinal cage, wherein a combination of said gap and said wall creates a socket securing said longitudinal end of said spinal cage; and

iv) an extension comprising a plurality of apertures and integral with said wall, wherein said extension is opposed to and coplanar with said gap and extends beyond said rim in a direction analogous to said lengthwise axis;

b) a cover comprising an aperture aligning with one of said extension's apertures and attachable to said extension, wherein said attached cover:

i) blocks egress from a majority of said extension's apertures; and

ii) blocks lateral egress of said spinal cage from said gap of said socket; and

c) fasteners securing said cover to said extension and said extension to vertebra.

20. The stabilizer of claim 19 , wherein said first lengthwise end is closed.
