Methods: forty patients with thoracolumbar burst fractures admitted to our hospital from April 2018 to December 2020 were randomly divided into study group and control group with 20 cases in each group. The control group was treated with short-segment minimally invasive internal fixation combined with injured vertebral bone graft, and the study group was treated with posterior approach anterior spinal canal decompression combined with injured vertebral internal fixation. The perioperative conditions, postoperative vertebral height, endplate angle and bony fusion of the two groups were evaluated and compared. Results: the operation time of the study group was shorter than that of the control group, and the amount of hemorrhage was less than that of the control group. At the stage of 12 months after operation, the height of the vertebral body in the study group was higher than that of the control group, and the endplate angle was smaller than that of the control group. The difference was statistically significant (P < 0.05). There was no significant difference in the osseous fusion between the two groups (P > 0.05). Conclusion: posterior anterolateral spinal canal decompression combined with internal fixation for thoracolumbar burst fractures has less intraoperative bleeding, which can reduce the risk of vertebral height loss and vertebral deformity on the basis of ensuring the effect of bony fusion.展开更多
