Abstract

A system having an expandable intervertebral fusion implant assembly for insertion between two vertebrae bodies. The system includes an anterior lumbar interbody component having an upper component and a lower component, each having an inner and outer surface, pivotally connected through a hinge. A distracting component includes a wedge having a superior and inferior surface that inserts between the upper and lower components of the anterior lumbar interbody component. The outer surface of the upper and the lower component contact endplates of two adjacent vertebral bodies.

Claims

1. A system comprising an expandable intervertebral fusion implant assembly for insertion between two vertebrae bodies, said system comprising:

an anterior lumbar interbody component comprising an upper component and a lower component, said upper component and said lower component each having an inner and outer surface, wherein the upper and lower components are pivotally connected through a hinge; and

a distracting component comprising a wedge having a superior and inferior surface, wherein said wedge inserts between said upper and lower components of said anterior lumbar interbody component,

wherein said outer surface of said upper and said lower component contact endplates of two adjacent vertebral bodies.

2. The system of claim 1, wherein said outer surface of said upper component and said lower component each comprise a vertebrae position device at a first end proximal to said hinge.

3. The system of claim 2, wherein said outer surface of said upper component and said lower component comprise a textured area, said texture area terminating at said vertebrae position device.

4. The system of claim 3, wherein said upper and said lower component each comprise a rib proximal to said first end.

5. The system of claim 4, wherein said distracting component comprises a securing component continuous with said wedge, wherein said securing component extends substantially perpendicular from said wedge.

6. The system of claim 5, wherein said securing component comprises a first and second fixation hole traversing said securing component, wherein the first and second fixation holes are positioned on an upper section and a lower section of said securing component, wherein said wedge is positioned between said upper section and said lower section.

7. The system of claim 6, wherein said securing component comprises bendable metal to accommodate curvature of vertebrae bodies.

8. The system of claim 7, wherein said distracting component comprises at least one alignment fin proximal to said wedge.

9. The system of claim 8, wherein said upper and said lower component each comprise at least one fin guide positioned complementary to said at least one alignment fin proximal to said wedge.

10. The system of claim 9, wherein said superior and inferior surface of said wedge are angled.

11. The system of claim 10, wherein a second end of said upper and said lower component is contoured to the shape of said securing component.

12. The system of claim 1, wherein said anterior lumbar interbody component is substantially D-shaped.

13. An expandable intervertebral fusion implant apparatus for insertion between two vertebrae bodies comprising:

an anterior lumbar interbody component comprising an upper component and a lower component, said upper component and said lower component each having an inner and outer surface, wherein the upper and lower components are pivotally connected through a hinge; and

a distracting component that comprises a wedge having a superior and inferior surface, wherein said wedge inserts between said upper and lower components of said anterior lumbar interbody component,

wherein said second end of said upper and said lower component each comprise a bone screw guide, wherein said bone screw guide is angled.

14. The apparatus of claim 13, wherein said distracting component comprises a securing component continuous with said wedge via an extension bar, wherein said securing component extends substantially perpendicular from said wedge.

15. The apparatus of claim 14, wherein said securing component is substantially square shaped having a top edge and a bottom edge, wherein said top edge and said bottom edge are substantially aligned with said outer surface of said upper component and said lower component.

16. The apparatus of claim 15, wherein said securing component comprises a first and second fixation hole traversing said securing component, wherein said first and second fixation holes are positioned diagonally on said securing component, wherein said wedge is positioned substantially in the middle of said securing component.

17. The apparatus of claim 16, wherein said fixation holes are angled complementary to the angled bone screw guides.

18. The apparatus of claim 17, wherein a second end of said upper and said lower component is contoured to the shape of said securing component.

19. The apparatus of claim 18, wherein said superior and inferior surface of said wedge are angled.

20. An expandable intervertebral fusion implant assembly for insertion between two vertebrae bodies comprising:

an anterior lumbar interbody component comprising an upper component and a lower component, wherein said upper and lower components are pivotally connected through a hinge;

a distracting component that comprises a wedge that inserts between said upper and lower components of said anterior lumbar interbody component;

a vertebrae position device at a first end proximal to said hinge;

a rib proximal to said first end;

a securing component continuous with said wedge;

a first and second fixation hole traversing said securing component;

at least one alignment fin proximal to said wedge; and

at least one fin guide positioned complementary to said at least one alignment fin proximal to said wedge.
