Abstract：Objective To investigate and compare the efficacy of percutaneous pedicle screw fixation and convention-al open reduction and internal fixation in the treatment of AO-A type thoracolumbar fractures without nerve injuries. Methods Seventy-two cases of AO-A type thoracolumbar fractures without nerve injuries were treated in our hospital from December 2014 to December 2016. The patients were randomly divided into two groups, the observation group (36 cases) treated with minimally invasive percutaneous pedicle screw fixation, the control group (36 cases) treated with open reduction and pedicle nail internal fixation. The perioperative indexes, imaging parameters, postoperative VAS score and ODI index were compared between the two groups. Results The bleeding volume in the observation group was (100. 82 ± 23. 53) ml, the incision length was (61. 92 ± 8. 93) mm, the hospitalization time was (9. 12 ± 2. 03) d, which were significantly lower than that in the control group (309. 28 ± 35. 67) ml, (128. 83 ± 13. 02)mm, (14. 83 ± 3. 18)d (t=8. 238,P<0. 05) respectively. The postoperative vertebral height, kyphosis, cobb angle, and sagittal index were better than those of before surgery in both of the two groups. The therapeutic effect in both group were significantly improved than before (P<0. 05); postoperative VAS score and ODI index were significantly lower than before surgery, and the observation group was significantly lower than the control group (t=7. 254, P<0. 05). Conclusion It demonstrated that the minimally invasive percutaneous pedicle screw internal fixation can effectively treat AO-A non-neurogenic thoracolumbar fractures, and is superior to traditional open reduc-tion in controlling intraoperative trauma, postoperative pain and postoperative recovery internal fixation.
