Treatment of Thoracolumbar Vertebral Fracture by Percutaneous cross Segment Pedicle Screw and Injured Vertebra Bone Graft

Abstract：Objective To investigate the surgical method and clinical effect of thoracolumbar vertebral fractures treated by percutaneous cross segment pedicle screw and injured vertebra bone graft. Methods 20 cases of thoracolumbar vertebral frac-tures without neural injury treated by percutaneous cross segment pedicle screw and injured vertebra bone graft during June 2013 to January 2015. There were 1 cases of T11 fractures,4 cases of T12 fractures,10 cases of L1 fractures,and 5 cases of L2 fractures. Incision length,blood loss volume,time off bed and complications were observed. Anterior vertebral height and Cobb angle were surveyed and analyzed before and after the operation. Results All the patients were followed up for a mean time of 18. 0 months(ranging from 9 to 24 months). Incision length was about 1. 5 cm. Average blood loss volume was 130 mL. Time off bed was two weeks. There was not any complication happened in this group,such as neural injury,infection,disunion,back muscle pain,screw breakage. When anterior vertebral height and Cobb angle were compared between pre - operation and post- operation,there was significant difference(P ﹤ 0. 05),but there was no significant difference between one week after opera-tion and final follow - up(P ﹥ 0. 05). Conclusion The operation of percutaneous cross segment pedicle screw and injured vertebra bone graft is a good method to treat thoracolumbar vertebral fractures,because of its less trauma,less bleeding,better recovery,less correction loss.
