Clinical Study Of Posterior Vertebral Fixation Combined With Vertebral And Posterolateral Bone Grafting For The Treatment Of Thoracolumbar Burst Fracture

Objective In this paper,the safety and clinical efficacy of the treatment of thoracolumbar vertebral burst fractures were treated by spinal biomechanics and clinical research.Methods 60 patients with unilateral or bilateral pedicle of thoracolumbar vertebral burst fractures were divided into observation group and control group.The observation group (posterior vertebral fixation combined with injured vertebral pedicle and posterior lateral bone graft),and the control group (cases of posterior vertebral fixation plus bone graft),30 cases.The changes of vertebral body height and Cobb angle were observed before operation and 1 week,3 months and 12 months post-operation.Results 60 patients were followed up for 12 months.There were no significant statistical differences in the Cobb and R value,before operation、1 week post-operation and 3 months post-operation between the observation group and the control group (P>0.05). The Cobb and R values have significant statistical differences between the observation group and the control group (P<0.05) at 12 months post-operation.Conclusion Experimental results further confirm that Posterior Vertebral Fixation Combined with Vertebral and Posterolateral Bone Grafting can be a safe and effective method in the treatment of thoracolumbar burst fracture.
