Abstract

The purpose of this study was to explore the clinical efficacy and safety of posterior pedicle screw fixation in the treatment of thoracolumbar burst fracture. A total of 120 patients with thoracolumbar burst fractures were selected from January 2014 to December 2016. 60 patients were divided into the study group, and 60 patients were as the control group. The patients in the study group were treated with posterior pedicle screw fixation. The control group was treated with posterior non-traumatic pedicle screw fixation. After treatment, there were six months follow up. The clinical indexes, complications, and the anterior aspect height ratio, the Cobb angle, and the numeric rating scales (NRS) score were compared between the two groups at one month, six months after the operation. Results were I incisions healed into two groups, and no infection occurred after the operation. The operation time of the study group was higher than that of the control group (p<0.05), and there was no statistical difference in the amount of bleeding and the length of stay between the two groups (p>0.05). At one month and six months after the operation, the anterior vertebral height of the two groups was significantly higher than before, and the Cobb angle and NRS score were substantially lower than those before surgery, the difference was statistically significant (p<0.05). The height of the leading edge of the injured vertebra was higher than that of the control group at six months after the operation. However, the difference was not statistically significant (p>0.05). Moreover, the angle of Cobb and the NRS score were lower than those of the control group (p<0.05). The occurrence of postoperative low back pain and biomechanical fixation failure in the study group were significantly lower than those in the control group (p<0.05). To conclude, through the posterior approach, the pedicle screw fixation can efficiently prevent kyphosis, correct the loss and reduce the postoperative complications. It is a useful method for the treatment of thoracolumbar burst fractures.
