[J] (31): doi: /j.issn Three-dimensional imaging guided vertebral pedicle screw placement: accuracy analysis Shao He-yang, Meng Li-juan (Department of Orthopedics, Luohe Hospital of Traditional Chinese Medicine, Luohe , Henan Province, China) Abstract BACKGROUND: Pedicle screw implantation is a common method to repair various spinal diseases, but there is a big difficulty in the safety and accuracy of screw placement. OBJECTIVE: To explore the effects of spinal pedicle screw implantation in the implementation of image guidance. METHODS: A retrospective analysis was performed on clinical data of 118 cases of pedicle screw implantation in the Luohe Hospital of Traditional Chinese Medicine from December 2010 to December They received internal fixation with pedicle screws. They were equally divided into two groups according to guidance method. Observation group underwent three-dimensional imaging of spinal navigation. Control group received conventional X-ray fluoroscopy. Screw placement and repair-related indexes were observed in the two groups. After implantation, they were followed up for 1 12 months. Postoperative complications were compared in both groups.

2 . RESULTS AND CONCLUSION: 59 patients in the observation group were implanted with 325 screws, and 59 patients in the control group were implanted with 319 screws. In the observation group, the excellent and good rate was 95% (319 screws). In the control group, the excellent and good rate was 78% (250 screws). There were significant differences in the excellent and good rate between the two groups (P < 0.05). The time required in screw placement was significantly shorter in the observation group than that in the control group (P < 0.05). Operation time and the intraoperative bleeding were significantly better in the observation group than in the control group (P < 0.05). The incidence rate of postoperative complications was lower in the observation group than in the control group (P < 0.05). These data suggest that under the guidance of three-dimensional imaging of spinal navigation, spine pedicle screw fixation can effectively shorten the time required for screw placement, improve the accuracy of implantation, and reduce the occurrence of postoperative complications.
