Abstract

An intervertebral implant includes a three-dimensional body and a securing plate. The three-dimensional body includes a front surface and a rear surface. The three-dimensional body further includes a plurality of boreholes for accommodating fixation elements. The intervertebral implant also includes a front plate disposed at the front surface of the three-dimensional body and has a plurality of boreholes. A securing plate can be fastened to the front plate.

First claim

What is claimed:

1. A method of implanting an intervertebral implant, the method comprising the steps of:
coupling a plate of the intervertebral implant to a body of the intervertebral implant such that a borehole defined by the plate is aligned with a partial borehole defined by the body, wherein the coupling step includes the step of restricting movement of the plate relative to the body in at least one degree of freedom;
after the coupling step, moving the plate and body along a first direction into an intervertebral disc space, the intervertebral disc space defined between a first vertebral body and a second vertebral body spaced vertically from the first vertebral body;
inserting a bone fixation element through the borehole and into the first vertebral body such that a portion of the bone fixation element faces the partial borehole, wherein the borehole extends along a central axis that is angled vertically with respect to the first direction.

2. The method of claim 1 , wherein after the moving step and before the inserting step the partial borehole faces the first vertebral body.

3. The method of claim 1 , wherein the coupling step includes the step of aligning a top surface of the plate with a top surface of the body with respect to a second direction, the second direction perpendicular to the first direction, such that the top surface of the plate and the top surface of the body both face one of the first vertebral body and the second vertebral body during the moving step.

4. The method of claim 3 , wherein the coupling step includes the step of aligning a bottom surface of the plate with a bottom surface of the body with respect to the second direction, such that the bottom surface of the plate and the bottom surface of the body both face the other of the first vertebral body and the second vertebral body during the moving step.

5. The method of claim 1 , wherein the coupling step includes the step of moving the plate relative to the body in a second direction, the second direction perpendicular to the first direction.

6. The method of claim 1 , wherein the coupling step includes the step of inserting a rail of one of the plate and the body into a recess of the other of the plate and the body.

7. The method of claim 1 , wherein the borehole is a first borehole, the partial borehole is a first partial borehole, and the coupling step includes the step of aligning a second borehole defined by the plate with a second partial borehole defined by the body.

8. The method of claim 7 , wherein the bone fixation element is a first bone fixation element, the method further comprising the step of inserting a second bone fixation element through the second borehole and into the first vertebral body such that a portion of the second bone fixation element faces the second partial borehole.

9. The method of claim 7 , wherein the bone fixation element is a first bone fixation element, the method further comprising the step of inserting a second bone fixation element through the second borehole and into the second vertebral body such that a portion of the second bone fixation element faces the second partial borehole.

10. The method of claim 9 , further comprising the steps of:
securing the first bone fixation element within the first borehole; and
securing the second bone fixation element within the second borehole such that at least a portion of the first bone fixation element is aligned with the second bone fixation element with respect to a second direction, the second direction perpendicular to the first direction.

11. The method of claim 7 , wherein the coupling step includes the step of aligning a third borehole defined by the plate with a third partial borehole defined by the body.

12. The method of claim 11 , wherein the bone fixation element is a first bone fixation element, the method further comprising the steps of:
inserting a second bone fixation element through the second borehole and into the first vertebral body such that a portion of the second bone fixation element faces the second partial borehole; and
inserting a third bone fixation element through the third borehole and into the second vertebral body such that a portion of the third bone fixation element faces the third partial borehole.

13. The method of claim 1 , further comprising, after the inserting step, the step of blocking the bone fixation element from backing out of the first borehole.

14. The method of claim 13 , wherein the blocking step includes the step of coupling a securing element to the plate such that movement of the securing element in a direction opposite the first direction is restricted.

15. The method of claim 1 , wherein the inserting step includes the step of rotating the bone fixation element about an axis.

16. The method of claim 1 , wherein the inserting step includes moving the bone fixation element through the borehole at an oblique angle with respect to the first direction.

17. The method of claim 1 , wherein the at least one degree of freedom includes the first direction and a direction opposite the first direction.

18. The method of claim 17 , wherein the at least one degree of freedom includes a second direction and a third direction opposite the second direction, the second direction perpendicular to the first direction.

19. The method of claim 1 , wherein the at least one degree of freedom includes a second direction and a third direction opposite the second direction, the second direction perpendicular to the first direction.
