Spinal stabilization systems and methods
First Claim
1. A method for inserting a spinal stabilization system in a human spine, comprising:
- making an incision in skin near human vertebrae to be stabilized;
pulling the incision toward a first one of the human vertebrae to be stabilized;
inserting a first bone fastener assembly in the incision and securing the first bone fastener assembly to the first human vertebra;
pulling the incision toward a second one of the human vertebrae to be stabilized;
inserting a second bone fastener assembly in the incision and securing the second bone fastener assembly to the second human vertebra;
creating a tissue plane between the first bone fastener assembly and the second human vertebra to be stabilized; and
releasing the incision before creating the tissue plane.

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.
