The possible complications of a pedicle screw fixation system include injury to neurologic and vascular structures resulting
from inaccurate placement of the instrumentation. In a review of 617 surgical cases in which pedicle screw implants were used,
Esses and co-authors reported a overall complication rate of 27.4%. The most common intraoperative problem was unrecognized
screw misplacement (5.2%). Fracturing the pedicle during screw insertion and iatrogenic cerebrospinal fluid leak occurred
in 4.2% of cases. Such a complication rate is not acceptable in clinical practice. In this paper, we discuss a computer-assisted
spine surgery system designed for real-time intraoperative localization of surgical instruments on precaptured images used
during surgery. Localization was achieved by combining image-guided stereotaxis with advanced opto-electronic position sensing
techniques. The insertion of pedicle screws can be directly monitored by interactive navigation using specially equipped surgical
tools. Our preliminary results showed no misplacement of pedicle screw, which have further confirmed the clinical potential
of this system.
