Systems, methods and tools for spinal surgery

1. A system for spinal surgery comprising:

a first bone anchor, said first bone anchor comprising a screw shank with a screw shank head that is a first part of a ball-in-socket joint, and a screw head movable with respect to said screw shank head that is a second part of said ball-in-socket joint;

a tubular member having:

a proximal end,

a distal end,

a working longitudinal channel running from said proximal end to said distal end, said working longitudinal channel sized to coaxially align with said screw head,

a slot positioned near said distal end within a wall of said tubular member;

a connector sized to be delivered through said working longitudinal channel from said proximal end of said tubular member to said distal end of said tubular member; and

a tool for causing at least a portion of said connector positioned at least partially within said working longitudinal channel to exit said working longitudinal channel via said slot.

2. The system of claim 1 wherein said tool includes:

a distal end adapted to engage a proximal end of said connector; and

an actuating surface located proximal to said distal end of said tool for turning said connector from a first position substantially aligned with said first bone anchor to a second position substantially transverse to said first bone anchor.

3. The system of claim 2 wherein the system includes a second bone anchor adapted to couple to said connector.

4. A method for spinal surgery comprising:

providing a bone anchor, said bone anchor comprising a screw shank and a screw head polyaxially coupled to said screw shank;

providing a tubular member, said tubular member having a working longitudinal channel therewithin, said screw head alignable with said working longitudinal channel, said tubular member having a slot therethrough in communication with said working longitudinal channel;

delivering a connector longitudinally through said working longitudinal channel of said tubular member; and

moving at least a portion of said connector out of said working longitudinal channel through said slot.

5. The method of claim 4 wherein delivering said connector longitudinally through said working longitudinal channel includes inserting said connector into said working longitudinal channel through an opening in a proximal end of said tubular member.

6. The method of claim 4 wherein moving at least said portion of said connector out of said working longitudinal channel includes applying pressure to said connector using a tool.

7. The method of claim 6 further comprising inserting at least a portion of said tool into said working longitudinal channel through an opening in a proximal end of said tubular member prior to applying pressure to said connector.

8. The method of claim 4 wherein moving at least said portion of said connector out of said working longitudinal channel includes rotating said connector from an orientation generally parallel to a longitudinal axis of the said tubular member to an orientation generally transverse to said longitudinal axis of said tubular member.

9. The method of claim 8 further comprising inserting a pin coupled to a distal end of said connector into an opening in said bone anchor, wherein said pin forms a center of rotation for rotating said connector.

10. A method for spinal surgery comprising:

providing a bone anchor, said bone anchor comprising a screw shank and a screw head polyaxially coupled to said screw shank;

providing a tubular member, said tubular member having a working longitudinal channel therewithin, said screw head alignable with said working longitudinal channel, said tubular member having a slot therethrough in communication with said working longitudinal channel;

moving a connector longitudinally through said working longitudinal channel of said tubular member; and

moving at least a portion of said connector out of said working longitudinal channel through said slot by rotating said connector from an orientation generally parallel to a longitudinal axis of the said tubular member to an orientation generally transverse to said longitudinal axis of said tubular member.

11. The method of claim 10 wherein moving said connector longitudinally through said working longitudinal channel includes inserting said connector into said working longitudinal channel through an opening in a proximal end of said tubular member.

12. The method of claim 10 wherein moving at least said portion of said connector out of said working longitudinal channel includes applying pressure to said connector using a tool.

13. The method of claim 12 further comprising inserting at least a portion of said tool into said working longitudinal channel through an opening in a proximal end of said tubular member prior to applying pressure to said connector.

14. The method of claim 10 further comprising inserting a pin coupled to a distal end of said connector into an opening in said bone anchor, wherein said pin forms a center of rotation for rotating said connector.
