Abstract：Objective: To analyze the effects of Sextant minimally invasive percutaneous pedicle screw internal fixation and open pedicle screw internal fixation on imaging indicators and recurrent fractures in the treatment of spinal fractures. Methods: A total of 80 patients with spinal fractures treated in our hospital from March 2020 to May 2021 were randomly divided into an observation group (Sextant internal fixation) and a control group (open internal fixation) by simple random number table method, 40 cases in each. The indexes during operation, imaging indexes, VAS, ODI, JOA scores before operation and 3 months after operation, and the incidence of complications were compared between the two groups. Results: During the operation, the incision length, intraoperative blood loss, postoperative drainage volume and operation time of the observation group were significantly lower than those of the control group (all P<0.05). Before surgery, there were no statistical differences in imaging indicators, VAS, ODI and JOA scores between the two groups (all P>0.05). Three months after operation, the imaging indexes (SI, COBB, anterior edge height of injured vertebrae) in both groups showed significant changes compared with those before surgery (all P<0.05),the increased value of SI, decreased value of COBB and increased height of injured vertebral front in the observation group were greater than those in the control group (all P<0.05); VAS, JOA, and ODI in both groups showed significant changes compared with those before surgery (all P<0.05),the decrease of VAS, increase of JOA and decrease of ODI in the observation group were all greater than those in the control group (all P<0.05); Compared with 25.00% of the total incidence of postoperative complications in the control group, the observation group was significantly lower at 7.50% (P<0.05). Conclusion: Compared with open pedicle screw internal fixation, Sextant minimally invasive percutaneous pedicle screw internal fixation in the treatment of spinal fractures can better protect the vertebral body stability and spinal nerve function, and reduce postoperative complications.
