ABSTRACT:
A spinal fixation access system includes a vertebral anchor with selectively attached extension members to extend percutaneously from the spine. The surgical procedure associated with this invention involves making small, discrete incisions for the placement of select vertebral anchors. The extension members retract soft tissue, muscle and the like to thereby provide visibility and access to the head of the anchor. Through the extension members, instrumentation such as a spine rod, set screw and other required hardware may be delivered to the anchors. Once a spine rod or other components are secured to the pedicle screws, the extension members are disengaged from the anchors and removed from the patient.
