Spinal implant system and methods of use

1. A method for treating a spine, the method comprising the steps of:

imaging a patient anatomy;

selecting an implant strategy for at least one bone fastener having a first member;

pre-operatively generating an image of at least a portion of a robot;

registering the imaging of the patient anatomy with the image of the robot;

engaging the first member with tissue of the patient anatomy via robotic guidance according to the implant strategy; and

subsequently, manipulating the patient anatomy.

2. A method as recited in claim 1 , further comprising the step of manually engaging a second member with the first member to connect the members.

3. A method as recited in claim 2 , wherein the step of manually engaging the members includes snap fitting the first member with the second member in a non-instrumented assembly.

4. A method as recited in claim 1 , wherein the step of manipulating the patient anatomy includes decompressing vertebrae.

5. A method as recited in claim 1 , wherein the step of manipulating the patient anatomy includes discectomy.

6. A method as recited in claim 1 , further comprising the step of inserting an interbody implant between a first vertebra and a second vertebra of the patient anatomy.

7. A method as recited in claim 1 , subsequent to the step of registering, further comprising the step of drilling a pilot hole in the tissue via robotic guidance according to the implant strategy.

8. A method as recited in claim 1 , subsequent to the step of registering, further comprising the step of tapping the tissue via robotic guidance according to the implant strategy.

9. A method as recited in claim 1 , wherein the step of imaging a patient anatomy includes pre-operatively generating three dimensional images of the patient anatomy.

10. A method as recited in claim 1 , wherein the step of imaging a patient anatomy includes pre-operatively generating a CT scan of the patient anatomy.

11. A method as recited in claim 1 , wherein the step of imaging a patient anatomy includes generating a scan with an O-Arm imaging device intra-operatively.

12. A method as recited in claim 1 , wherein the step of selecting the implant strategy includes pre-operative planning according to the imaging of the patient anatomy.

13. A method as recited in claim 1 , wherein the at least one bone fastener includes a plurality of pedicle screws and the implant strategy includes a plurality of screw trajectories for positioning the screws with a first vertebra and a second vertebra of the patient anatomy.

14. A method as recited in claim 1 , further comprising:

connecting the first member with an instrument; and

inserting the instrument through an incision to engage the first member with the tissue of the patient anatomy,

wherein the image of the robot is generated before the instrument is inserted through the incision.

15. A method for treating a spine, the method comprising the steps of:

pre-operatively generating a CT scan of a patient anatomy including at least one vertebra;

selecting an implant strategy according to the CT scan for at least one bone screw shaft;

pre-operatively generating fluoroscopic images of at least a portion of a robot;

registering the CT scan with the fluoroscopic images;

engaging the bone screw shaft with the vertebra via robotic guidance according to the implant strategy;

subsequently, manipulating the patient anatomy; and

manually engaging an implant receiver with the bone screw shaft to comprise a bone screw.

16. A method as recited in claim 15 , wherein the step of manually engaging includes snap fitting the implant receiver with the bone screw shaft in a non-instrumented assembly.

17. A method as recited in claim 15 , subsequent to the step of registering, further comprising the step of tapping the vertebra via robotic guidance according to the implant strategy.

18. A method as recited in claim 15 , wherein the step of manipulating includes decompressing vertebrae of the patient anatomy.

19. A method for treating a spine, the method comprising the steps of:

imaging vertebral tissue;

selecting an implant strategy for at least one bone screw shaft;

pre-operatively generating an image of a robot connected with the vertebral tissue;

registering the imaging of the vertebral tissue with the image of the robot;

connecting a surgical driver with the bone screw shaft, the surgical driver including an image guide oriented relative to a sensor to communicate a signal representative of a position of the bone screw shaft;

engaging the bone screw shaft with the vertebral tissue via robotic guidance according to the implant strategy;

subsequently, manipulating the vertebral tissue; and

manually engaging an implant receiver with the bone screw shaft to comprise a bone screw.

20. A method as recited in claim 19 , wherein the step of manually engaging includes snap fitting the implant receiver with the bone screw shaft in a non-instrumented assembly.
