Spinal stabilization systems and methods using minimally invasive surgical procedures
First Claim
1. A system for performing spine surgery, said system comprising:
- a first bone screw configured to be screwed into a first vertebra;
a first collar rotatably coupled to the first bone screw, said first collar comprising a first slot having a slot width;
a second bone screw configured to be screwed into a second vertebra;
a second collar rotatably coupled to the second bone screw, said second collar comprising a second slot;
a rod, said rod having a width less than the slot width;
a first sleeve comprising a first channel, said first sleeve having a length longer than a length of the first bone screw, said first sleeve comprising a distal end at one end of the first sleeve and a proximal end at a second end of the first sleeve, said first channel being formed in an opening of a sleeve wall of the first sleeve, and said first channel extending along at least a portion of the length of the first sleeve;
a first closure member configured to be secured to the first collar for securing the rod within the first slot;
a second sleeve, said second sleeve having a length longer than a length of the second bone screw;
a second closure member configured to be secured to the second collar for securing the rod within the second slot,wherein the distal end of the first sleeve detachably couples to the first collar so that the proximal end of the first sleeve extends away from the first collar and the first channel is aligned with the first slot, andwherein after the rod, the first closure member and the first bone screw are implanted, the distal end of the first sleeve is decoupled from the first collar.

Abstract
A spinal stabilization system may be formed in a patient. In some embodiments, a minimally invasive procedure may be used to form a spinal stabilization system in a patient. Bone fastener assemblies may be coupled to vertebrae. Each bone fastener assembly may include a bone fastener and a collar. The collar may be rotated and/or angulated relative to the bone fastener. Detachable members may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The detachable members may allow for alignment of the collars to facilitate insertion of an elongated member in the collars. An elongated member may be positioned in the collars and a closure member may be used to secure the elongated member to the collars.

23. A surgical system for securing a rod to two bone screws, each bone screw being secured to a different vertebra, said system comprising:
-
a first bone screw, said first bone screw comprising a first slot having a slot width; a second bone screw, said second bone screw comprising a second slot; a first sleeve comprising a first channel, said first sleeve having a length longer than a length of the first bone screw, said first sleeve comprising a distal end at one end of the first sleeve and a proximal end at a second end of the first sleeve, said first channel being formed in an opening of a sleeve wall of the first sleeve and said first channel extending along at least a portion of the length of the first sleeve; a second sleeve, said second sleeve having a length longer than a length of the second bone screw, wherein said second sleeve detachably couples to the second bone screw; a rod, said rod having a width less than the slot width; wherein the distal end of the first sleeve detachably couples to the first bone screw, such that the proximal end of the first sleeve extends away from the first bone screw, such that the first channel is aligned with a first slot in the first bone screw, and such that the first bone screw and first sleeve are substantially coaxial, and wherein after the rod and the first bone screw are implanted, the distal end of the first sleeve is decoupled from the first bone screw. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A system for performing spine surgery, said system comprising:
-
a first bone fastener configured to be fastened to a first vertebra, said first bone fastener comprising a first slot having a slot width; a second bone fastener configured to be fastened to a second vertebra, said second bone fastener comprising a second slot; a rod, said rod having a width less than the slot width; a first sleeve comprising a first channel, said first sleeve having a length longer than a length of the first bone fastener, said first sleeve comprising a distal end at one end of the first sleeve and a proximal end at a second end of the first sleeve, said first channel being formed in an opening of a sleeve wall of the first sleeve and said first channel extending along at least a portion of the length of the first sleeve; a first closure member configured to be secured to the first bone fastener for securing the rod within the first slot; a second sleeve, said second sleeve having a length longer than a length of the second bone fastener, wherein the second sleeve and the second bone fastener detachably couple together; a second closure member configured to be secured to the second bone fastener for securing the rod within the second slot, wherein the distal end of the first sleeve detachably couples to the first bone fastener so that the proximal end of the first sleeve extends away from the first bone fastener and so that the first channel is aligned with the first slot, and wherein after the rod, the first closure member, and the first bone fastener are implanted, the distal end of the first sleeve is decoupled from the first bone fastener. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
