Clinical Effect And Influencing Factors Analysis For Transpedicular Self-bone Grafting And Posterior Fixation In The Treatment Of Thoracolumbar Burst Fractures

Objective To evaluate the clinical effect and influence factors for posterior fixation and transpedicular self-bone grafting in the treatment of thoracolumbar burst fractures. Discussion of thoracolumbar burst fractures in patients after open reduction and bone volume of the vertebral injury, after the loss of cobb angles, fracture healing time. Provide a reference for clinical treatment.Method Thirty-five cases were treated by transpedicular self-bone grafting and posterior fixation.Measure the bone-grafting volume.The neuropathic function were analysed. Cobb angel, anterior and posterior vertebral wall compressed ratios and dural sac were shown preoperatively and postoperatively by using X-ray radiograph and CT . Result All cases were followed-up 4-28 months(average 13 months). The bone-grafting volume was 4.25(3-7.5) cm3. The neuropathic function improved obviously. Cobb angel, anterior and posterior vertebral wall compressed ratios and dural sac postoperatively were improved than those preoperation. The losing of the vertebrae′s heigh preoperatively and postoperatively are considered statistically significant (P<0.05). Conclusion Inner vertebral self-bone grafting and posterior fixation can increase the stability of the anterior and medial column of the spine. There is a good clinical effect for posterior fixation and transpedicular self-bone grafting in the treatment of thoracolumbar burst fractures. Effect of the impact of those factors and bone graft surgery, the experience associated with reduction.
