Abstract
Objective: To evaluate the long-term outcomes of short segment pedicle screw fixation with transforaminal interbody fusion. Subject and method: A prospective study was performed the patients with isolated unstable thoracolumbar burst fractures treated by posterior short segment pedicle screw fixation and transforaminal thoracolumbar interbody fusion at 108 Military Central Hospital between January 2013 and January 2017. All patients were followed up for a minimum of 1 year. Demographic data, neurologic status, loss of anterior vertebral body heights, vertebral sagittal and regional sagittal angle were analysed at preoperative, after surgery, and at last follow up. Treatment-related complications were recorded. Result: There were 36/40 patients who met the inclusion and exclusion criteria with a mean follow-up duration of 53.3 months (range, from 17 to 73 months). The mean operative time was 117.6 minutes (range, from 90 to 165). The post-operative radiographs demonstrated a good reduction of kyphotic deformity and it was well maintained until last follow-up. There were 9/36 patients with incomplete neurological deficit was improved one to two ASIA grades. 27 patients without paraplegia on admission remained neurological intact after surgery. Conclusion: Short segment pedicle screw fixation with transforaminal interbody fusion is a surgical method had good long-term outcomes for treatment of thoracolumbar burst fractures, Denis IIB. The good bone union was 91.7% and the hardware failure was 16.7%.
