Spinal implant system and method
A method for treating a spine is provided. The method includes the steps of: disposing an interbody implant adjacent a posterior portion of an intervertebral disc space; connecting a surgical instrument with at least one fixation element fastened with tissue adjacent the posterior portion; and manipulating the surgical instrument such that tissue adjacent the posterior portion engages the interbody implant and one or more vertebra rotate about the interbody implant. Spinal implants, surgical instruments and systems are disclosed.
1. A surgical system comprising:
a spinal implant comprising a body including a first vertebral engaging surface and a second vertebral engaging surface being disposable adjacent a posterior portion of an intervertebral disc space;
bone graft disposable within the intervertebral disc space; and
a surgical instrument to compress tissue with the spinal implant such that one or more vertebra rotate about the spinal implant, the surgical instrument including a cork screw tether.
2. A surgical system as recited in claim 1 , wherein the surgical instrument includes extenders connected with the cork screw tether.
3. A surgical system as recited in claim 1 , wherein the cork screw tether includes extenders and a movable wedge disposed therebetween.
4. A surgical system as recited in claim 1 , wherein the spinal implant includes a clover-leaf configuration that is configured to engage tissue adjacent the posterior portion.
5. A surgical system as recited in claim 1 , wherein the spinal implant includes a dumbbell configuration that is configured to be inserted adjacent the posterior portion in a vertical access direction with a TLIF approach.
6. A surgical system as recited in claim 1 , wherein the spinal implant includes a posteriorly expanding cage.
7. A surgical system as recited in claim 1 , further comprising first and second screws, the surgical instrument comprising a first extender that is coupled to the first screw and a second extender that is coupled to the second screw, the screws being configured to be attached with vertebrae such that the extenders can selectively rotate the vertebrae.
8. A surgical system as recited in claim 7 , further comprising a wedge disposed between the extenders and an actuator including a handle and the cork screw tether, the handle being configured to be rotated to wind the cork screw tether about the handle and translate the wedge laterally between the extenders to cause the extenders to rotate.
9. A surgical system comprising:
an interbody implant disposable within an intervertebral disc space;
bone graft disposable within the intervertebral disc space; and
a surgical instrument configured to compress tissue with the interbody implant such that one or more vertebra rotate about the interbody implant, the surgical instrument including an actuator, the actuator including a handle, a cork screw tether and a wedge, the handle being configured to be rotated to wind the cork screw tether about the handle and translate the wedge.
10. A surgical system as recited in claim 9 , wherein the surgical instrument includes extenders connected with the cork screw tether.
11. A surgical system as recited in claim 9 , wherein the cork screw tether includes extenders, the wedge being disposed between the extenders.
12. A surgical system as recited in claim 9 , wherein the interbody implant includes a clover-leaf configuration.
13. A surgical system as recited in claim 9 , wherein the interbody implant includes a dumbbell configuration.
14. A surgical system as recited in claim 9 , wherein the interbody implant includes a posteriorly expanding cage.
15. A surgical system as recited in claim 9 , further comprising first and second screws, the surgical instrument comprising a first extender that is coupled to the first screw and a second extender that is coupled to the second screw, the screws being configured to be attached with vertebrae such that the extenders can selectively rotate the vertebrae.
16. A surgical system comprising:
a spinal implant; and
a surgical instrument including a cork screw tether, the surgical instrument being configured to compress tissue with the spinal implant such that one or more vertebra rotate about the spinal implant.
17. A surgical system as recited in claim 16 , further comprising first and second screws, the surgical instrument comprising a first extender that is coupled to the first screw and a second extender that is coupled to the second screw, the screws being configured to be attached with vertebrae such that the extenders can selectively rotate the vertebrae.
18. A surgical system as recited in claim 16 , wherein the surgical instrument comprises an actuator, the actuator including a handle, a wedge and the cork screw tether, the handle being configured to be rotated to wind the cork screw tether about the handle and translate the wedge.
19. A surgical system as recited in claim 16 , wherein the surgical instrument includes extenders connected with the cork screw tether.
20. A surgical system as recited in claim 16 , wherein the cork screw tether includes extenders and a wedge, the wedge being disposed between the extenders.
