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:
an implant body comprising opposite first and second side surfaces, opposite first and second end surfaces that each extend from the first side surface to the second side surface, and opposite first and second vertebral engaging surfaces that each extend from the first side surface to the second side surface and from the first end surface to the second end surface, the implant body defining an opening that extends through the first side surface, the first end surface defining a cavity, the first vertebral engaging surface defining a track, the track being in communication with the cavity, the track being continuously curved from a first end of the track to an opposite second end of the track; and
a member having a first portion movably disposed in the cavity and a second portion movably disposed in the track.

2. A spinal implant as recited in claim 1 , wherein the implant body includes an aperture that extends through the first vertebral engaging surface and the second vertebral engagement surface, the aperture being in communication with the opening.

3. A spinal implant as recited in claim 1 , wherein the implant body includes a first hole that extends through the first side surface and a second hole that extends through the second side surface.

4. A spinal implant as recited in claim 3 , wherein the implant body includes an aperture that extends through the first vertebral engaging surface and the second vertebral engaging surface, the holes each being in communication with the aperture.

5. A spinal implant as recited in claim 3 , wherein the first hole is coaxial with the second hole.

6. A spinal implant as recited in claim 1 , wherein the track has a maximum length defined by a distance from the first end to the second end, the track having a continuous radius of curvature along the maximum length of the track.

7. A spinal implant as recited in claim 1 , wherein the track comprises a single radius defining an arcuate configuration.

8. A spinal implant as recited in claim 1 , wherein the cavity is defined by an inner surface of the implant body, the inner surface including a first end and a second end that define a range of movement in the cavity.

9. A spinal implant as recited in claim 1 , further comprising a surgical instrument, wherein the first portion of the member comprises a socket configured for disposal of an end of the surgical instrument.

10. A spinal implant as recited in claim 1 , further comprising a surgical instrument, wherein the surgical instrument comprises a threaded outer surface that mates with a threaded inner surface of the first portion of the member to connect the surgical instrument with the member.

11. A spinal implant as recited in claim 1 , wherein the second end surface defines a bullet nose of the implant body.

12. A spinal implant as recited in claim 1 , wherein the member is slidably engageable with the track.

13. A spinal implant comprising:
an implant body comprising opposite first and second side surfaces, opposite first and second end surfaces that each extend from the first side surface to the second side surface, and opposite first and second vertebral engaging surfaces that each extend from the first side surface to the second side surface and from the first end surface to the second end surface, the implant body defining an aperture that extends through the first and second vertebral engaging surfaces, the implant body defining an opening that extends through the first side surface, the opening being in communication with the aperture and oriented to implant a fastener oblique to a lateral axis of a subject body and adjacent to an intervertebral space of the subject body, the first end surface defining a cavity, the first vertebral engaging surface defining a track, the track being continuously curved from a first end of the track to an opposite second end of the track; and
a member having a first portion movably disposed in the cavity and a second portion movably disposed in the track.

14. A spinal implant as recited in claim 13 , wherein the track is in communication with the cavity, the member being slidably engageable with the track.

15. A spinal implant as recited in claim 13 , wherein the track has a maximum length defined by a distance from the first end to the second end, the track having a continuous radius of curvature along the maximum length of the track.

16. A spinal implant as recited in claim 13 , wherein the cavity is defined by an inner surface of the implant body, the inner surface including first end and a second end that define a range of movement in the cavity.

17. A spinal implant as recited in claim 13 , further comprising a surgical instrument, wherein the first portion of the member comprises a socket configured for disposal of an end of the surgical instrument.

18. A spinal implant as recited in claim 13 , further comprising a surgical instrument, wherein the surgical instrument comprises a threaded outer surface that mates with a threaded inner surface of the first portion of the member to connect the surgical instrument with the member.

19. A spinal implant as recited in claim 13 , wherein the second end surface defines a bullet nose of the implant body.

20. A spinal implant comprising:
an implant body comprising opposite first and second side surfaces, opposite first and second end surfaces that each extend from the first side surface to the second side surface, and opposite first and second vertebral engaging surfaces that each extend from the first side surface to the second side surface and from the first end surface to the second end surface, the implant body defining an aperture that extends through the first and second vertebral engaging surfaces, the implant body defining an opening that extends through the first side surface and the first vertebral engaging surface, the opening being in communication with the aperture, the first end surface defining a cavity, the first vertebral engaging surface defining a track that is in communication with the cavity, the track having a maximum length defined by a distance from a first end of the track to an opposite second end of the track, the track having a continuous radius of curvature along the maximum length of the track;
a member movably disposed in the cavity and slidably engageable with the track, the member comprising a threaded inner surface;
a surgical instrument comprising a threaded outer surface that mates with the threaded inner surface to connect the surgical instrument with the member.
