#$%^&*AU2016201395B220171026.pdf#####SYSTEM AND METHOD FOR WIRE-GUIDED PEDICLE SCREW STABILIZATION OF SPINAL VERTEBRAE ABSTRACT An improved system and method for positioning screws and rods to immobilize bones is provided. Specifically, the system and method is optimal for performing transforaminal lumbar interbody fusion (TLIF) and other interbody fusions in the spine. The system involves pedicle screws (101, 102) detachably connected to wires (103) that guide rods (104) down to the screws (101, 102). The wires are strong, narrow, flexible, adjustable in tension, and easily disconnected from the screws after rod placement via a process such as cutting, radiating, burning, dissolving, etc.. The use of wires to place the rods avoids the conventional bulky tower apparatuses of the prior art while at the same time enhancing the accuracy of placement. One of the preferred methods involves relying upon the natural lordotic curvature of the spine and the narrow diameter of the wires to insert many elements through a single minimally invasive incision.
