Abstract:
BACKGROUND:Photoelectric navigation-aided percutaneous pedicle screw placement has been developed extensively,but its accuracy,safety and effectiveness have not yet been confirmed by evidence-based medicine.OBJECTIVE:To compare the curative efficacy of photoelectric navigation-aided percutaneous pedicle screw placement and traditional open posterior pedicle screw fixation for thoracolumbar fractures.METHODS:Sixty patients with thoracolumbar fractures were equivalently randomized to treatment and control groups and then underwent photoelectric navigation-aided percutaneous pedicle screw placement and traditional open posterior pedicle screw fixation,respectively.The perioperative indexes,imaging indexes,function recovery and incidence of complications were compared between two groups.RESULTS AND CONCLUSION:(1) The Visual Analogue Scale scores,intraoperative blood loss,radiant times,and hospitalization time in the treatment group were significantly less than those in the control group (P ＜ 0.05).(2) The operation time did not differ significantly between two groups (P ＞ 0.05).(3) The postoperative sagittal Cobb angle,and percentage of anterior height in the vertebral body in the two groups were significantly improved compared with those before surgery (P ＜ 0.05),but all above imaging indexes showed no significant differences between two groups (P ＞ 0.05).The endplate-screw angle in the treatment group was significantly less than that in the control group (P ＜ 0.05).(5) The excellent and good rate of placement in the treatment group was significantly higher than that in the control group (P ＜ 0.05).(6) These results suggest that compared with the traditional open posterior pedicle screw fixation,the photoelectric navigation-aided percutaneous pedicle screw placement exhibits high placement accuracy,less radiant times,less trauma,less blood loss and rapid functional recovery.
