Abstract：Objective To investigate the clinical effect of paraspinal muscle approach and GSS internal fix-ation system in the treatment of thoracolumbar vertebral fractures .Methods Ninety cases of thoracolumbar frac-tures admitted into our hospital from Mar .2011 to Aug.2013 were randomly divided into the study group and the control group ,with 45 cases in each group .Patients in the study group were treated with paraspinal muscle approach+GSS fixation system and patients in the control group were treated with traditional midline approach +GSS fixation system.The operation information , preoperative and postoperative X-rays at different time ,VAS and Oswestry dys-function index ( ODI) changes were compared between the two groups .Results In the study group ,the operative time was (86.3 ±14.7)min,blood loss was(155.7 ±38.2)mL,surgery incision residual cavity volume was (10.3 ±2.6)mL,postoperative drainage was ( 106.6 ±21.7)mL,which were all significantly lower than those of the con-trol group(P<0.05).There was no significant difference in the postoperative hospitalization time between the two groups(P>0.05).The vertebral height ratio,Cobb angle were significantly improved at 1 week after operation in both groups compared with preoperative values (P<0.05).At the last follow-up,in the study group,the vertebral height loss was (1.67 ±0.21) mm,Cobb angle loss was (1.45 ±0.81)°,which showed no significant difference when compared to the control group ( P>0.05 ) .The VAS scores at the third month and the last follow-up in the study group were significantly lower than those of the control group (P<0.05).At the end of the follow-up,the ex-cellent ratio of ODI in the study group was 75.56%,which was higher than the control group of 53.33%,and the ODI at the last follow-up in study group was also higher than that of the control group (P<0.05).Conclusion Paraspinal approach and GSS internal fixation system in the treatment of thoracolumbar vertebral fracture has advan -tages of shorter operation time ,simpler operation ,firmer fixation and better recovery .
