Abstract

A spinal implant comprises an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an outer surface that defines an oblique surface. A wall is connectable with the implant body and translatable relative to the oblique surface. Systems and methods are disclosed.

First claim

What is claimed is:

1. A spinal implant system comprising:
a spinal construct comprising an implant body, a connecting member, a nut and a plate, the implant body defining an opening, the connecting member being movably disposed within the opening, the plate being coupled to the connecting member such that the plate is translatable along the implant body, the nut being coupled to the plate and comprising a first engagement feature, the plate comprising a second engagement feature; and
an instrument comprising a third engagement feature configured for engagement with the first engagement feature and a fourth engagement feature configured for engagement with the second engagement feature to connect the instrument with the spinal construct,
wherein the third engagement feature is configured to be tightened with the first engagement feature to draw the implant body, the plate and the instrument together and hold the implant body, the plate and the instrument in a fixed orientation.

2. The spinal implant system recited in claim 1 , wherein the implant body extends along a longitudinal axis between opposite proximal and distal walls, the implant body comprising opposite anterior and posterior walls each extending from the proximal wall to the distal wall, the proximal wall comprising an outer surface extending at an oblique angle relative to the longitudinal axis, the outer surface defining the opening.

3. The spinal implant system recited in claim 2 , wherein the opening extends through an inner surface of the proximal wall and the outer surface, the opening having opposite first and second rounded ends, the opening having a uniform height from the first end to the second end.

4. The spinal implant system recited in claim 1 , wherein the instrument comprises a first arm, a second arm and a bridge connecting the first arm with the second arm, the third engagement feature extending from the bridge, the fourth engagement feature being defined by a tip of at least one of the arms.

5. The spinal implant system recited in claim 4 , wherein the third engagement feature includes a threaded end of a pivot bolt.

6. The spinal implant system recited in claim 5 , wherein the pivot bolt extends parallel to the arms.

7. The spinal implant system recited in claim 6 , wherein the pivot bolt is configured to be tightened with the first engagement feature to draw the implant body, the plate and the instrument together and hold the implant body, the plate and the instrument in a fixed orientation.

8. The spinal implant system recited in claim 4 , wherein the second engagement feature includes at least one groove.

9. The spinal implant system recited in claim 6 , wherein the pivot bolt is configured to be tightened with the socket to draw the implant body, the plate and the instrument together and hold the implant body, the plate and the instrument in a fixed orientation.

10. The spinal implant system recited in claim 1 , wherein the first engagement feature includes a socket and the third engagement feature includes a threaded end of a pivot bolt that is configured for disposal in the socket.

11. The spinal implant system recited in claim 1 , wherein the second engagement feature includes a pair of recesses and the fourth engagement feature includes a pair of tabs, the tabs each being configured for disposal in one of the recesses.

12. The spinal implant system recited in claim 1 , wherein:
the first engagement feature includes a socket and the third engagement feature includes a threaded end of a pivot bolt that is configured for disposal in the socket; and
the second engagement feature includes a pair or recesses and the fourth engagement feature includes a pair of tabs, the tabs each being configured for disposal in one of the recesses.

13. The spinal implant system recited in claim 12 , wherein the pivot bolt is configured to be tightened with the socket to draw the implant body, the plate and the instrument together and hold the implant body, the plate and the instrument in a fixed orientation.

14. The spinal implant system recited in claim 1 , wherein the third engagement feature is configured for engagement with the first engagement feature and the fourth engagement feature is configured for engagement with the second engagement feature to provisionally fix the plate and the implant body with the instrument.

15. A spinal implant system comprising:
a spinal construct comprising an implant body, a connecting member, a nut and a plate, the implant body defining an opening, the connecting member being movably disposed within the opening, the nut being coupled to the plate and comprising a first engagement feature, the plate being coupled to the connecting member such that the plate is translatable along the implant body, the plate comprising a second engagement feature; and
an instrument comprising a third engagement feature configured for engagement with the first engagement feature such that tightening of the third engagement feature with the first engagement feature draws the implant body, the plate and the instrument together and holds the implant body, the plate and the instrument in a fixed orientation,
wherein the first engagement feature includes a socket and the third engagement feature includes a pivot bolt configured for disposal in the socket.

16. The spinal implant system recited in claim 15 , wherein the pivot bolt has a threaded outer surface.

17. The spinal implant system recited in claim 15 , wherein:
the instrument comprises a first arm, a second arm and a bridge that connects the first arm to the second arm, the third engagement feature extending from the bridge;
the pivot bolt has a threaded outer surface.

18. A spinal implant system comprising:
a spinal construct comprising an implant body, a connecting member, a nut and a plate, the implant body defining an opening, the connecting member being movably disposed within the opening, the nut being coupled to the plate and comprising a socket, the plate being coupled to the connecting member such that the plate is translatable along the implant body, the plate comprising a pair of recesses; and
an instrument comprising a threaded pivot bolt configured for engagement with the socket, the instrument comprising a pair of tabs each configured for disposal in one of the recesses,
wherein tightening of the pivot bolt with the socket while the tabs are disposed in the recesses draws the implant body, the plate and the instrument together and holds the implant body, the plate and the instrument in a fixed orientation.
