Abstract：Objective To investigate the clinical effect of long screws in injured vertebrae pry reset in the treatment of AO classification type A thoracolumbar fracture. Methods From April 2018 to December 2020, 46 patients with type A thoracolumbar fracture without neurological symptoms treated in Department of Orthopedics, Enshi Hospital of Enshi Tujia and Miao Autonomous Prefecture, Hubei Province were selected as the research objects. According to the random number table method, the patients were divided into two groups: the pry teset group (redution and fixation by prying with long screw of injured vertebra, 25 cases) and the indirect reset group (after the reduction of adjacent vertebrac distraction, the injured vertebral was fixed with short screw, 21 cases). The general operation conditions (wound length, operation time, intraoperative blood loss and related complications) of the two groups were observed and compared. Cobb angle and anterior height ratio of injured vertebrae were measured and compared between the two groups. Results Both groups were followed up 12-18 months (median, 14 months). There were no significant differences in incision length, operation time, and intraoperative blood loss between the two groups (P ＞ 0.05). No postoperative complications were observed in the two groups. Overall analysis showed that there were statistically significant differences in Cobb angle and vertebral height ratio between the two groups at different time points, between groups and interaction (P ＜ 0.05). Intra-group comparison showed that the vertebral height ratio increased and the lateral Cobb angle decreased between the two groups immediately after operation (P ＜ 0.05). In indirect reduction group, there was significant difference between the last follow-up and the immediate postoperative follow-up (P ＜ 0.05). There were statistically significant differences in Cobb angle and vertebral height between the two groups at immediate and last follow-up after operation (P ＜ 0.05). At the last follow-up, no screw loosening, fracture and kyphosis were found in both groups. Conclusion The treatment of type A thoracolumbar fracture with the long screw of injured vertebra is ideal, reliable, and can maintain the reduction. The clinical effect is satisfactory.
