Abstract: ［Abstract］ Objective To observe the clinical effect of pedicle bone graft and pedicle screw in the treatment of thoracolumbar burst fracture. Methods From January 2014 to January 2017，100 patients with thoracolumbar burst fracture were divided into two groups（50 cases per group）. The patients in the control group were treated with lateral bone grafting plus pedicle screw fixation，and the observation group were treated with pedicle bone graft and pedicle screw internal fixation. The operative time，intraoperative bleeding volume，pain score，kyphosis angle were compared between the two groups. The height of injured vertebrae and the grade of spinal cord nerve injury. Results There was no significant difference in intraoperative bleeding volume between the two groups（P>0.05）. The pain scores of the two groups were significantly lower than those before operation（P<0.05），and the anterior and posterior edge height of injured vertebrae were significantly higher than those before operation（P<0.05），and the kyphosis angle was significantly higher than that before operation（P<0.05）. The pain score of the observation group was lower than that of the control group（P<0.05），and the height of the injured vertebrae was higher than that of the control group（P<0.05），and the kyphotic angle was lower than that of the control group（P<0.05）. Conclusion In the treatment of thoracolumbar burst fracture，the treatment with pedicle bone graft and pedicle screw fixation can effectively reduce the pain and correct the height and kyphosis angle of injured vertebrae. It is beneficial to promote the effective recovery of spinal cord nerve injury.
