Abstract: A wireless pedicle screw system and method of use for fixation and/or stabilization of vertebral bodies using pedicle screws and rods or plates is described. The wireless pedicle screw system includes a dilator tube having a generally elongated body defined by a continuous wall. The elongated body has a proximal end, a distal end, and an inner lumen running the length of the elongated body sized to receive and enclose various pedicle screw implant instruments. Positioned at the distal end are alignment/positioning members constructed to properly aid a surgeon in aligning the dilator tube to portions of the vertebra. Proper placement about the vertebra using the engagement members results in the ability to insert pedicle screws, resulting in minimizing tissue trauma, reducing operating room time, reducing X-Ray radiation exposure, and eliminating the need for k-wire guidance.
