Abstract

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.
