Abstract: Objective To investigate the clinical long-term effect of posterolateral laminar bone grafting combined with posterolateral bone grafting in the treatment of thoracolumbar burst fractures. Methods From January 2014 to November 2016, 25 cases of posterior short segment pedicle screw fixation combined with posterolateral laminar bone graft fusion were performed in our department(group A). 19 cases were treated with transpedicular bone grafting combined with posterolateral laminar fusion(group B). All patients were underwent thoracolumbar X-ray and CT examination before surgery, 1 week after surgery, before and 1 year after internal fixation. Results There was no significant difference in anterior compression ratio and Cobb angle between the two groups before operation, 1 week after operation and before internal fixation(P>0.05). 1 year after internal fixation, there were significant differences in anterior vertebral compression ratio and Cobb angle between the two groups(P<0.05). Conclusion Posterior short segment pedicle screw fixation combined with transpedicular bone grafting combined with posterolateral laminar bone grafting is an effective method for the treatment of thoracolumbar burst fractures and is worthy of clinical application.
