Abstract：Objective To analyze the effect of different internal fixation methods in the treatment of thoracolumbar spinal fractures,and to provide a reference for the selection of specific surgical methods in clinical practice.Methods The clinical data of 61 patients with thoracolumbar spinal fractures treated in our hospital from January 2014 to January 2017 were retrospectively analyzed,and all patients were treated with single segment fixation,bone graft and fusion.According to the different methods of internal fixation,61 patients were divided into the control group(30 cases)and the observation group (31 cases).The control group was treated with pedicle screw fixation,and the observation group was treated with general spinal internal fixation.The curative effect and the incidence rate of complication between the two groups were compared,and the amount of bleeding and the operation time of the patients were compared.Results There was no significant difference in the height of the Cobb angle,the posterior edge and the front edge of the vertebral body between the two groups of patients(P＞0.05).The amount of bleeding in the observation group was less than that of the control group,and the operation time in the observation group was shorter than that in the control group,with significant difference (P＜0.05).The incidence rate of complications in the observation group was 0.00%,which was lower than that in the control group(13.33%),with significant difference(P＜0.05).Conclusion Compared with pedicle screw fixation,the use of general spinal fixation for pedicle screw fixation can significantly reduce the amount of intraoperative blood loss and shorten the operation time,and less complications and adverse reactions,high safety,therefore,in clinical practice,the general spinal internal fixation is the first choice for the treatment of thoracolumbar spine fracture with single segmental fixation and bone graft fusion.
