Abstract

A modular implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient including a first spacer portion, a second spacer and a container having a first end and a second end, the first end of the container constructed to operably engage a first spacer and the second end of the container constructed to operably engage the second spacer.

First claim

What is claimed is:

1 . An implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient comprising:
a first spacer body; a second spacer body; and a porous and expandable container, the container having a first end, a horizontally opposing second end, a vertically facing top side and a vertically facing bottom side, wherein the first end of the container is coupled to the first spacer body and the second end of the container is coupled to the second spacer body, and wherein the top side and the bottom side of the container are exposed between the first spacer body and the second spacer body.

2 . The implant of claim 1 , wherein the first and second spacers are comprised of PEEK.

3 . The implant of claim 1 , wherein the container is comprised of PET.

4 . The implant of claim 1 , wherein at least one of the first spacer body and the second spacer body includes at least one fill opening that extends horizontally through the at least one of the first spacer body and the second spacer body.

5 . The implant of claim 1 , wherein at least one of the first and second spacer bodies includes markings disposed on a vertically facing surface thereof.

6 . The implant of claim 5 , wherein the markings project vertically outward to engage the surrounding anatomy.

7 . The implant of claim 1 , wherein at least one of the spacer bodies includes vertically facing outward projections to engage the surrounding anatomy.

8 . The implant of claim 1 , further including at least one connecting rod extending horizontally between the first spacer body and the second spacer body, and passing through the container.

9 . The implant of claim 8 , wherein the connecting rod includes at least one fill opening in communication with an interior of the container.

10 . The implant of claim 1 , including an angulation feature.

11 . The implant of claim 1 wherein the container is comprised of a conformable material.

12 . An implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient comprising:
a first spacer body having a horizontal width dimension and a vertical height dimension; a second spacer body having a horizontal width dimension and a vertical height dimension; and a porous and expandable container, having a horizontal width dimension between a first end and a horizontally opposing second end, wherein the horizontal width dimension of the container is greater than the horizontal width dimension of the first spacer body and greater than the horizontal width dimension of the second spacer body, wherein the first spacer body is coupled to the first end of the container, and wherein the second spacer body is coupled to the second end of the container.

13 . The implant of claim 12 , further including at least one connecting rod extending horizontally between the first spacer body and the second spacer body, and passing through the container.

14 . The implant of claim 13 , wherein the connecting rod includes at least one fill opening in communication with an interior of the container.

15 . The implant of claim 14 , wherein at least one of the first spacer body and the second spacer body includes at least one fill opening that extends horizontally through the at least one of the first spacer body and the second spacer body and communicates with the connecting rod.

16 . The implant of claim 13 , wherein the connecting rod is rotationally rigid such that the first spacer body cannot rotate with respect to the second spacer body about a longitudinal axis of the rod.

17 . The implant of claim 13 , wherein the connecting rod includes at least one fill opening in communication with an interior of the container.

18 . The implant of claim 12 , wherein the first spacer body includes a fill opening that extends horizontally through the first spacer body.

19 . The implant of claim 18 , wherein the second spacer body includes a textured surface located perpendicular to a surface through which the fill opening is defined.

20 . An implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient comprising:
a porous and expandable container including a first end, a second end and an interior space; a first rigid spacer body coupled to a first end of the container; a second rigid spacer body coupled to a second end of the container; and a rod spanning between the first spacer body and the second spacer body, and extending through the container, wherein the rod is disposed completely within the interior space of the container for an entire expanse between the first spacer body and the second spacer body, wherein a fill opening is defined through the first spacer body which communicates with the rod, and wherein the rod includes a fill channel that communicates with the fill opening and with the interior space of the container.
