Abstract

Embodiments herein are generally directed to spinal implants, systems, apparatuses, and components thereof that can be used in spinal fusion and/or stabilization procedures, as well as methods of installation. The spinal implants may include an intervertebral spacer and a plate member.

First claim

What is claimed is:

1. A vertebral fusion device, comprising:
a spacer member comprising a first mating element; and
a fixation member comprising a first bore extending therethrough and a second mating element, the second mating element configured to engage the first mating element,
wherein the fixation member articulates with respect to the spacer member such that when the second mating element is coupled to the first mating element, the second mating element is configured to pivot with respect to the first mating element,
wherein at least a portion of the vertebral fusion device is configured to be positioned between adjacent vertebral bodies, and
wherein the fixation member translates laterally along a horizontal plane with respect to the spacer member.

2. The vertebral fusion device of claim 1 , wherein the first mating element is disposed on a curved portion of an outer side surface of the spacer member.

3. The vertebral fusion device of claim 2 , wherein the curved portion is located at a trailing end of the spacer member.

4. The vertebral fusion device of claim 1 , wherein the first mating element comprises a groove.

5. The vertebral fusion device of claim 1 , wherein the second mating element comprises a protrusion.

6. The vertebral fusion device of claim 1 , wherein the fixation member is jointedly coupled to the spacer member.

7. The vertebral fusion device of claim 1 , wherein the fixation member is configured to extend beyond an upper surface of the spacer member.

8. The vertebral fusion device of claim 1 , further comprising a locking member configured to inhibit movement of the fixation member relative to the spacer member.

9. A vertebral fusion device, comprising:
a spacer member having an upper surface and an opposed lower surface and comprising a first mating element having a groove extending along a curved path; and
a fixation member comprising a first bore extending therethrough and a second mating element including a coupling portion extending along a curved path and configured to be received in the groove, the second mating element configured to engage the first mating element, wherein the first and second mating elements have the same radius of curvature,
wherein the fixation member articulates with respect to the spacer member such that when the second mating element is coupled to the first mating element, the second mating element is configured to pivot with respect to the first mating element,
wherein the spacer member is configured to be positioned between first and second vertebral bodies such that the upper surface of the spacer member is configured to engage the first vertebral body and the lower surface of the spacer member is configured to engage the second vertebral body,
wherein the fixation member translates laterally with respect to the spacer member.

10. The vertebral fusion device of claim 9 , wherein the first mating element is disposed on a curved portion of an outer side surface of the spacer member.

11. The vertebral fusion device of claim 10 , wherein the curved portion is located at a trailing end of the spacer member.

12. The vertebral fusion device of claim 9 , wherein the second mating element comprises a protrusion.

13. The vertebral fusion device of claim 9 , wherein the fixation member is jointedly coupled to the spacer member.

14. The vertebral fusion device of claim 9 , wherein the fixation member is configured to extend beyond an upper surface of the spacer member.

15. The vertebral fusion device of claim 9 , further comprising a locking member configured to inhibit movement of the fixation member relative to the spacer member.

16. A vertebral fusion device, comprising:
a spacer member having a leading end, a trailing end, a first side, a second side, an upper surface and a lower surface, wherein a length of the spacer member extends from the leading end to the trailing end and a width of the spacer member extends from the first side to the second side, wherein the length of the spacer member is greater than the width of the spacer member, wherein the trailing end comprises a curved portion, the curved portion having a first mating element in the form of a groove extending along the curved portion; and
a fixation member comprising a second mating element including a coupling portion extending along a curved path and configured to be received in the groove, the second mating element configured to slidably engage the first mating element, wherein the first and second mating elements have the same radius of curvature,
wherein the fixation member articulates with respect to the spacer member such that when the second mating element is coupled to the first mating element, the second mating element is configured to pivot with respect to the first mating element,
wherein the vertebral fusion device is configured to be positioned between adjacent vertebral bodies, and
wherein the first mating element translates with respect to the spacer member.

17. The vertebral fusion device of claim 16 , wherein the second mating element comprises a protrusion.

18. The vertebral fusion device of claim 16 , wherein the fixation member is jointedly coupled to the spacer member.

19. The vertebral fusion device of claim 16 , wherein the fixation member is configured to extend beyond the upper surface of the spacer member.

20. The vertebral fusion device of claim 16 , further comprising a locking member configured to inhibit movement of the fixation member relative to the spacer member.
