Abstract

An intervertebral instrument includes a shaft having distal and proximal ends. The proximal end of the shaft includes an attaching feature connected to handle. The shaft defines a pair tracks disposed along a portion of the surface thereof. The distal end includes a pair of wings. Each track guides instruments and implants along the intervertebral instrument. The implants are configured to receive bone graft or bone enhancers. The distal end of the shaft may include a removably attachable tip configured to engage the implants. The implants and the removably attachable tip form an implantable intervertebral disk. An intervertebral instrument and implant kit is also disclosed. A method of inserting intervertebral implants is also disclosed.

Claims (23)

1. An intervertebral instrument and implant kit comprising:

an intervertebral instrument including a shaft having distal and proximal ends, the shaft defining at least one track at least partially disposed along a portion of the surface thereof, the distal end of the shaft including a removable section that is removable from the shaft, the removable section being configured and dimensioned to distract an intervertebral disk space defined between two vertebrae, the at least one track being configured and dimensioned to guide instruments and intervertebral implants used in intervertebral procedures toward the intervertebral disk space; and

at least one intervertebral implant selectively secured to the removable section of the shaft and including a pair of members, each member having a body with top, bottom, inside, and outside surfaces, the top and bottom surfaces including ridges disposed thereon, the inside surface having at least one protuberance, the at least one protuberance configured and dimensioned to engage the intervertebral instrument, wherein at least one of the members is configured and dimensioned to receive bone graft or bone enhancers to enable bone ingrowth.

2. The intervertebral instrument and implant kit according to claim 1 , further comprising a handle disposed at the proximal end of the shaft for manipulation of the shaft.

3. The intervertebral instrument and implant kit according to claim 1 , wherein the at least one intervertebral implant and the removable section of the shaft are collectively and selectively removable from the shaft.

4. The intervertebral instrument and implant kit according to claim 3 , wherein the removable section of the shaft and the at least one intervertebral implant collectively define an implantable intervertebral disk that is separable from the intervertebral instrument for implantation within a patient.

5. The intervertebral instrument and implant kit according to claim 1 , wherein the removable section of the shaft includes a pair of wings for distracting the intervertebral disk space.

6. An intervertebral instrument and implant kit comprising:

an intervertebral instrument including a shaft having distal and proximal ends, the shaft defining a track at least partially disposed along a portion of the surface thereof, the distal end including a removable section that is removable from the shaft and is positionable within an intervertebral disk space defined between two vertebrae to distract the two vertebrae, the track guiding instruments and intervertebral implants used in intervertebral procedures toward the intervertebral disk space; and

an intervertebral implant selectively secured to the removable section of the shaft and including a pair of members, each member having a body with top, bottom, inside, and outside surfaces, the top and bottom surfaces including ridges disposed thereon, the inside surface having a protuberance, the protuberance securable to the intervertebral instrument.

7. The intervertebral instrument and implant kit according to claim 6 , wherein the intervertebral implant and the removable section of the shaft are collectively separable from the intervertebral instrument for implantation within a patient.

8. The intervertebral instrument and implant kit of claim 6 , wherein at least one of the members defines at least one opening for the reception of bone graft or bone enhancers to enable bone ingrowth.

9. The intervertebral instrument and implant kit according to claim 6 , further comprising a handle disposed at the proximal end of the shaft for manipulation of the shaft.

10. The intervertebral instrument and implant kit according to claim 6 , wherein the removable section of the shaft includes a pair of wings for distracting the intervertebral disk space.

11. An intervertebral instrument and implant kit comprising:

an intervertebral instrument including a shaft, the shaft defining a pair of tracks at least partially disposed along a portion of opposite sides of the shaft, the tracks providing a guide toward an intervertebral disk space defined between two vertebrae for at least one of instruments and intervertebral implants used in intervertebral procedures, a distal end of the shaft being positionable within the intervertebral disk space to distract the two vertebrae; and

an intervertebral implant including a pair of members, with a first member positioned along one of the pair of tracks and a second member positioned along the other of the pair of tracks, each of the first and second members having a protuberance securable to the intervertebral instrument that facilitates the movement of the respective member along one of the tracks;

wherein the distal end of the shaft includes a removable section disposed between the first and second members, the removable section being selectively removable from the shaft.

12. The intervertebral instrument and implant kit according to claim 11 , wherein the first and second members are separable from the intervertebral instrument.

13. The intervertebral instrument and implant kit of claim 11 , wherein at least one of the members defines at least one opening for the reception of bone graft or bone enhancers to enable bone ingrowth.

14. The intervertebral instrument and implant kit according to claim 11 , further comprising a handle disposed at the proximal end of the shaft for manipulation of the shaft.

15. The intervertebral instrument and implant kit according to claim 11 , wherein the removable section of the shaft, the first member, and the second member are collectively separable from the intervertebral instrument for collective implantation within a patient.

16. The intervertebral instrument and implant kit according to claim 11 , wherein the removable section of the shaft includes a pair of wings for distracting the intervertebral disk space.
