ABSTRACT
ObjectiveTo evaluate the efficacy of short-segment transpedicular fixation combined with augmentation vertebroplasty in treatment of thoracolumbar burst fractures. MethodsFrom November 2006 to September 2009, 37 patients with thoracolumbar burst fracture were admitted and received transpedicular fixation combined with calcium sulfate cement augmentation vertebroplasty, and the clinical data including fracture types, complications and following-up results were collected for analysis. The multimethod evaluation strategies involved the anterior vertebral body height, the sagittal Cobb's angle, the restoration of nervous function, internal fixation failure, visual analogue scale (VAS) and Oswestry disability index (ODI) were retrospective analyzed. Results All patients were followed up for average 19 months (range, 14-37). There were no internal fixation failure, loss of reduction, neurological complications in all the patients. In 16 patients with partial neurologic deficits, 14 initially improved at the final follow-up, with no deterioration of neurologic functions. The mean time of calcium sulfate cement obvious absorption and union was 3 months and 5 months postoperatively, respectively. The anterior vertebral body height was 55.40%before surgery and 85.46% after surgery on average, ended up with 82.35%. The sagittai Cobb's angle was improved from 22.45° to 6.86°, ended up with 9.66° on average. The mean VAS and ODI at the final followup were respectively 1.2 and 20.4 on average. ConclusionShort-segment transpedicular fixation combined with augmentation vertebroplasty appears to be effective in achieving stable biomechanics with high security,which seems to be a feasible option in the management of thoracolumbar burst fractures.
