Abstract：Objective To investigate the therapeutic effect of posterior vertebral pedicle screw and single Shima Shiumine screw reduction fixation on traumatic type B thoracolumbar fracture. Methods The clinical data about 86 patients with traumatic type B thoracolumbar fracture who were admitted into our hospital were retrospectively analyzed. These patients were divided into two groups according to the operation mode:observation group(n = 41)and control group( n = 45). The patients in observation group were treated by posterior vertebral pedicle screw and single Shima Shiumine screw fixation, however,the patients in control group were treated by traditional across the injured vertebra short segment fixation. The pain score in different time points,Cobb angle and centrum anterior border compression ratio,ASIA neural function grading and ODI score before and after treatment were observed and compared between the two groups. Results The operation time,hemorrhage volume during operation and one month after operation and the last fouow-up in observation group were significantly lower than those in control group( P < 0. 05). However there were no significant differences in hospitalization time,follow-up time and centrum anterior border compression ratio there were no significant differences in VAS score,Cobb angle and ODI score before operation and one month after operation between two groups( P > 0. 05),but VAS score,Cobb angle and ODI score in the last follow-up in observation group were significantly lower than those in control group( P < 0. 05). There was no significant difference in ASIA distribution before operation and one year after treatment between two groups( P > 0. 05),however,the ASIA distribution before treatment was superior to that after treatment for both groups(P < 0. 05). Conclusion The posterior vertebral pedicle screw and single Shima Shiumine screw reduction fixation in treatment of traumatic type B thoracolumbar frac-ture has the advantages of decreasing postoperative VAS score,Cobb angle loss and degeneration of intervertebral disc,with shorter operation time and less hemorrhage volume during operation.
