Abstract

A spinal implant comprises an implant body extending between an anterior surface and a posterior surface, and including a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least one opening oriented to implant a fastener oblique relative to a lateral axis of a subject body and adjacent an intervertebral space of the subject body. The implant body defining a cavity such that a surgical instrument is connectable with the implant body adjacent the cavity and movable relative to the implant body. Systems, surgical instruments and methods are disclosed.

First claim

What is claimed is:

1. A spinal implant comprising:
a body defining a first cavity and a second cavity, the second cavity extending transverse to the first cavity, the second cavity being in communication with the first cavity;
a connector comprising a first portion movably disposed in the first cavity and a second portion movably positioned in the second cavity; and
a screw comprising a head and a threaded shank, the head being positioned in a screw hole of the body, the shank extending through an aperture of the body, the screw hole being spaced apart from the first cavity and the second cavity and in communication with the aperture, the aperture being spaced apart from the first cavity and the second cavity.

2. The spinal implant recited in claim 1 , wherein the first portion includes a threaded inner surface defining a socket.

3. The spinal implant recited in claim 1 , wherein the aperture extends through opposite top and bottom surfaces of the body.

4. The spinal implant recited in claim 1 , wherein the second cavity is continuously curved from a first end of the second cavity to an opposite second end of the second cavity.

5. A spinal implant comprising:
a body comprising opposite top and bottom surfaces and opposite first and second end surfaces each extending from the top surface to the bottom surface, the first end surface defining a first cavity, the top surface defining a second cavity, the body comprising an aperture extending through the top and bottom surfaces and a screw hole extending through the first end surface, the screw hole being in communication with the aperture; and
a connector comprising a first portion movably disposed in the first cavity and a second portion movably positioned in the second cavity, the first cavity being spaced apart from the screw hole.

6. The spinal implant recited in claim 5 , wherein the top surface extends perpendicular to the first end surface.

7. The spinal implant recited in claim 5 , wherein the first cavity is in communication with the second cavity.

8. The spinal implant recited in claim 5 , wherein first portion includes a threaded inner surface configured for engagement with a threaded outer surface of an instrument.

9. The spinal implant recited in claim 5 , wherein an interface between the top and bottom surfaces and the second end surface defines a bullet nose.

10. The spinal implant recited in claim 5 , wherein the body comprises opposite first and second side surfaces each extending from the top surface to the bottom surface and from the first end surface to the second end surface, the first cavity extending into the first end surface without extending through at least one of the first and second side surfaces.

11. The spinal implant recited in claim 5 , wherein the body comprises opposite first and second side surfaces each extending from the top surface to the bottom surface and from the first end surface to the second end surface, the body comprising a first hole extending through the first side surface and a second hole extending through the second side surface, the holes being in communication with the aperture.

12. The spinal implant recited in claim 11 , wherein one of the first and second side surfaces includes only one hole.

13. The spinal implant recited in claim 5 , wherein the aperture is unobstructed.

14. The spinal implant recited in claim 5 , further comprising a screw comprising a head and a threaded shank, the head being positioned in the screw hole, the shank extending through the aperture.

15. The spinal implant recited in claim 5 , wherein the second cavity includes opposite first and second ends that define a range of translation of the first portion within the first cavity.

16. The spinal implant recited in claim 5 , wherein the second cavity is continuously curved from a first end of the second cavity to an opposite second end of the second cavity.

17. The spinal implant recited in claim 5 , wherein the second cavity comprises a single radius defining an arcuate configuration.

18. A spinal implant comprising:
a body comprising opposite proximal and distal surfaces and opposite first and second end surfaces each extending continuously from the proximal surface to the distal surface, the first end surface defining an arcuate first track, the proximal surface defining an arcuate second track;
a connector comprising a first portion movably disposed in the first track and a second portion movably positioned in the second track; and
a screw comprising a head and a threaded shank, the head being positioned in a screw hole of the body, the shank extending through an aperture of the body, the screw hole being spaced apart from the first track and the second track and in communication with the aperture, the aperture being spaced apart from the first track and the second track.

19. The spinal implant recited in claim 18 , wherein the top surface extends perpendicular to the first end surface.

20. The spinal implant recited in claim 18 , wherein the first cavity is in communication with the second cavity.
