PEDICLE DRILL GUIDE FOR SPINAL SURGERY

摘要

A Pedicle Drill Guide is a radiolucent device which allows preliminary positioning of a needle/trochar near the pedicle in the AP view and adjusting the final position of the lateral view without changing the initial position of the AP position. This guide allows simultaneous alignment of both AP and Lateral views for ultimate ideal or perfect pathway for the pedicle cannulization.

主权项

1. A method of positioning a K-wire into a vertebral pedicle during spinal surgery comprises:
positioning a pedicle drill guide into an opening and onto the vertebrae pedicle, the pedicle drill guide having a central hole for a stabilizing anchor pin and a plurality of satellite holes spaded from the center hole; placing a stabilizing pin into the center hole and anchoring a stabilizing pin into the bone; rotating the drill guide about the anchored stabilizing pin to align one of the satellite holes with the approximate far lateral edge of the pedicle on the AP view and the center axis of the pedicle on the lateral view; and inserting a K-wire into the satellite hole and drilling or otherwise securing the K-wire to the pedicle.
