Abstract: 【Abstract】〓Objective〓To compare the short term efficacy of pedicle screw fixation with intra-sacrospinal muscular approach and conventional approach for treating thoracolumbar fractures without nerve injury..Methods〓Fifty cases with thoracolumbar fractures without nerve injury undergoing fractured vertebral pedicle screw fixation and bone grafting from April 2009 to April 2013 were randomized into the observation group (paraspinal muscle approach) and the control group (conventional approach) with 25 cases in each group..Blood loss,.operative time,.postoperative drainage and hospitalization time were recorded in two groups,.and preoperative VAS scores and postoperative VAS scores after one year,.vertebral compression ratio and Cobb angle were compared in two groups. Results〓Blood loss, operative time, postoperative drainage, and hospital stay in the observation group were significantly less than those in the control group (P<0.05). There were no significant difference in preoperative VAS score, vertebral compression ratio and Cobb angle between two groups (P>0.05), and these were decreased one year after operation in two groups..VAS score in observation group was significantly decreased than that in control group,.but the difference of vertebral compression ratio and Cobb angle between the two groups was no statistically significant(P>0.05). Conclusion〓In treating thoracolumbar fractures without injured nerve,.the paraspinal muscle pedicle screw fixation plus vertebral bone grafting was less injury, faster postoperative recovery and better short term efficacy.
