Abstract: [Abstract] Objective To investigate the clinical efficacy of posterior 1/3 injured vertebrae corpectomy reconstruction in treatment of thoracolumbar burst fractures and its influence on spinal nerve function.Methods 82 patients with thoracolumbar burst fractures were randomly divided into observation group and control group，with 41 cases in each group.The observation group underwent posterior 1/3 corpectomy reconstruction，decompression and internal fixation，the control group underwent anterior subtotal corpectomy reconstruction，decompression and internal fixation.The surgical conditions，imaging findings，ASIA spinal cord function grading，pain Visual Analogue Scale（VAS）scores and Japanese Orthopaedic Association（JOA）scores  before and after surgery between the two groups were compared.Results The operative time，intraoperative blood loss and postoperative drainage in the observation group were lower than these in the control group，while the bone graft fusion rate was significantly higher than that in the control group（P<0.05）；At final flowup，the JOA score and ASIA grading in the observation group was significantly higher than the control group，while the VAS score，the veaebral height loss and Cobb angle loss were significantly lower than the control group（P<0.05）.The incidence of complications in the observation group was 2.44%，showed no significant difference with 4.88% in the control group（P>0.05）.Conclusion Posterior 1/3 corpectomy reconstruction for thoracolumbar burst fractures can improve the spinal cord nerve function and reduce vertebral correction loss，improve the quality of functional rehabilitation.
