Objective:To investigate the surgical therapeutic result of thoracolumbar fracture without neurological damage by percutaneous pedicle screw fixation with fixation through the pedicle of fractured vertebra.Methods:From October2008to October2009,a total of40thoracolumbar-fracture patients were divided into two groups. Group A:20cases were included in the open pedicle screw fixation,Group B:20cases were in percutaneous pedicle screw fixation with injured vertebra.The perioperative index including the surgical blood loss, surgical draining loss, surgical time, hospital stay and VAS score, the Cobb’s angle, the Oswestry index, and anterior height of the fracture vertebral body were compared.Results:There were5patients failed in follow-up,3patients in A group and2in B group. There were significant differences in the surgical blood loss (A:370.59±52.73, B:68.89±19.97, p<0.05), surgical draining loss(p<0.05), surgical time (A:2.19±0.32, B:1.48±0.18, p<0.05), VAS score (A:2.33±0.47, B:1.11±0.32, p<0.05)and Oswestry index (A:42.36±4.33, B:14.13±3.30.. p<0.05) between the two groups. The Cobb’s angle (A:16.94±3.42, B:15.67±3.53, p>0.05), hospital stay (A:17.17±2.35, B:11.06±2.10, p>0.05) and anterior height of the fracture vertebral body (A:26.78±4.71, B:22.61±4.27, p>0.05) were all significantly different between pre-operation and post-operation in each group.There was no significant difference in postoperative improvement of Cobb’s angle in each group in the follow-up(P>0.05) but there was significant difference in postoperative improvement of anterior height (P<0.05) of fractured vertebral body in the two groups.Conclusion:Achieved with open surgery minimally invasive percutaneous internal fixation in injured vertebral surgery postoperative height improvement and has no obvious difference on the cobb’s Angle improved, and in the operation time, blood loss, postoperative lumbar back pain improved and flow has a larger advantage. For thoracolumbar compression fractures without decompression, percutaneous pedicle screw fixation for choice, trauma small, curative effect affirmation, can yet be regarded as a better clinical treatment method.
