Abstract:
Objective To investigate the clinical value of computer-assisted navigation system (CANS) in pedicle screw placement. Methods From August 2002 to June 2006, we carried out 66 cases of pedicle screw placement under the guidance of CANS; 66 cases of traditional pedicle screw placement were set as a control. Results The mean operation time of CANS group was significantly shorter [(142.3?5.3) min vs (173.4?7.1) min; t=-28.301, P=0.000] and the blood loss was significantly fewer [(798.3?10.9)ml vs (912.2?14.3) ml; t=-51.463, P=0.000] than those in the control. X-ray and CT scan respectively showed that the placement of pedicle screw in CANS group was significantly more accurate than that in the control. (?2=29.424, P=0.000; ?2=36.829, P=0.000). Conclusion Pedicle screw placement under the guidance of CANS is more accurate, safe, and micro-invasive than traditional operation.
