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 surgical system comprising:
an implant comprising:
a first endplate, wherein the first endplate comprises a planar portion with protrusions and an extension portion;
a second endplate;
a first ramped body extending between the first endplate and the second endplate, wherein the first ramped body comprises at least one upwardly facing ramp engaging the first endplate and at least one downwardly facing ramp engaging the second endplate;
an actuator in engagement with the first ramped body, wherein rotation of the actuator causes translation of the first ramped body, thereby causing expansion of the implant; and
a first socket formed through the extension portion of the first endplate, wherein the first socket extends completely above the planar portion of the first endplate; and

a first anchor configured to fasten the implant to the patient, wherein the anchor is received in the first socket.

2. The device of claim 1 , wherein the first socket is attached to the first endplate.

3. The device of claim 2 , further comprising a second anchor to fasten the implant to the patient and wherein the implant further comprises a second socket, attached to the second endplate, configured to receive the second anchor.

4. The device of claim 3 , wherein at least one of the first anchor and the second anchor is curved and configured to pierce a bone of the patient to fasten the implant to the patient.

5. The device of claim 4 , wherein at least one of the first anchor and the second anchor is configured to have a t-shaped cross-section and sharp edges to pierce the bone of the patient to fasten the spacer to the patient.

6. The device of claim 5 , wherein the implant is configured to expand in a manner such that the first endplate and the second endplate are parallel.

7. The device of claim 5 , wherein the implant is configured to expand in a manner such that the first endplate and the second endplate are non-parallel.

8. A surgical system comprising:
an implant comprising:
a first endplate, wherein the first endplate comprises a planar portion with protrusions and an extension portion;
a second endplate;
a first ramped body extending between the first endplate and the second endplate;
an actuator in engagement with the first ramped body, wherein rotation of the actuator causes translation of the first ramped body, thereby causing expansion of the implant; and
a first socket formed through the extension portion of the first endplate, wherein the first socket extends completely above the planar portion of the first endplate; and

a first anchor configured to fasten the implant to the patient, wherein the anchor is received in the first socket.

9. The device of claim 8 , wherein the first socket is attached to the first endplate.

10. The device of claim 9 , further comprising a second anchor to fasten the implant to the patient and wherein the implant further comprises a second socket, attached to the second endplate, configured to receive the second anchor.

11. The device of claim 10 , wherein at least one of the first anchor and the second anchor is curved and configured to pierce a bone of the patient to fasten the implant to the patient.

12. The device of claim 11 , wherein at least one of the first anchor and the second anchor is configured to have a t-shaped cross-section and sharp edges to pierce the bone of the patient to fasten the spacer to the patient.

13. The device of claim 12 , wherein the implant is configured to expand in a manner such that the first endplate and the second endplate are parallel.

14. The device of claim 13 , wherein the implant is configured to expand in a manner such that the first endplate and the second endplate are non-parallel.
