Abstract

Abstract:

Objective　To evaluate the clinical effect of the Short-segment pedicle screw fixation with bone grafting and non-fusion in treatment of thoracolumbar burst fractures.　Method　51 patients with thoracolumbar burst fractures between January 2011 and August 2013 included for treatment by hort-segment pedicle screw fixation with bone grafting and non-fusion of fractured vertebra.　Result　The 51 patients were followed up for 3~26 months (mean 18 months). The vertebral height and kyphosis angle in all patients showed no significant loss; There was no no loosening of fixations or breakage of screws and rods. Postoperative CT scan demonstrated further improvement of the spinal canal narrowing, there was an average improvement of 2-3 grade in the degree of recovery of spinal cord injury according to Frankel assessment criteria.　Conclusion　Adopting of the injured vertebra fixation for thoracolumbar burst fractures can increase postoperative spinal stability, facilitate kyphosis correction, retain the thoracic and lumbar motion segment, which can effectively prevent the occurrence of traumatic disc degeneration and help restoration of spinal cord function.
