Abstract：BACKGROUND:Traditional treatment of thoracolumbar fractures through posterior central approach may induce trauma. Wiltseet al have proposed the paraspinal approach of vertebrae pedicle screw in the treatment of thoracolumbar fractures. However, this treatment is restricted due to deficient exposure and high surgical technique. It’s widely concerned to reduce surgical trauma and achieve better restoration effect.
<br> OBJECTIVE:To analyze the surgical indications and advantages of vertebrae pedicle screws in the treatment of thoracolumbar fractures through the modified transmultifidus approach.
<br> METHODS:From September 2011 to September 2013, 30 patients with thoracolumbar fractures were treated with vertebrae pedicle screw in Chengdu University Affiliated Hospital. The involved patients were divided into two groups, receiving pedicle screw fixation through the normal approach and the improved paraspinal approach, respectively.
<br> RESULTS AND CONCLUSION:The improved paraspinal approach obviously shortened the screw placement time and the surgical time, reduced blood loss, and improved visual analogue scale scores, compared with traditional posterior central approach of vertebrae pedicle screws in the treatment of thoracolumbar fractures. There was no significant difference in the postoperative improvement of vertebral height and Cobb angles. The modified transmultifidus approach is better than posterior central approach in the improvement of postoperative pain, but shows no difference in the screw placement time, surgical time and blood loss, in treatment of thoracolumbar fractures.
