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.

Dependent claims

A method of implanting a spinal stabilization system, comprising:

forming an incision at a desired site through skin of a patient;
anchoring a first bone fastener assembly to a first vertebral body at a first target location, said first bone fastener assembly comprising a first bone screw and a first collar, said first collar coupled to the first bone screw;
disposing a first sleeve between the incision and the first bone fastener assembly, the first sleeve having a first proximal end region and a first distal end region with a first passage defined therebetween, the first sleeve defining a first channel in communication with the first passage along at least portion of a length of the first sleeve the first distal end region being disposed proximate the first bone fastener assembly and the first proximal end region being disposed proximate the incision;
anchoring a second bone fastener assembly to a second vertebral body at a second target location, said second bone fastener assembly comprising a second bone screw and a second collar, said second collar coupled to the second bone screw;
disposing a second sleeve towards the second bone fastener assembly, the second sleeve having a second proximal end region and a second distal end region with a second passage defined therebetween, the second sleeve defining a second channel in communication with the second passage along at least a portion of a length of the second sleeve, the second distal end region being disposed proximate the second bone fastener assembly and the second proximal end region being disposed proximate the incision;
inserting an elongate member through the incision and along the first passage to a position adjacent the first collar;
and
securing the elongate member to the first collar.
