| Objective:Evaluation of pedicle screw system, based on the use of spinal vertebrae by bone grafting to treat thoracolumbar burst fracture of the clinical efficacy and safety and reliability, in order to provide scientific evidence for clinical use.Methods:Patient selection based on the selection of mindong hospital orthopedic patients with thoracolumbar burst fracture, using one-blind and random methods were divided into the non-bone graft group and the bone graft group. Non-bone graft group:posterior spinal decompression and open reduction and pedicle screw system fixation; bone Group:Posterior decompression and open reduction and arch by the intraspinal vertebral body bone graft and pedicle screw system fixation. By observing two groups of patients with preoperative, intraoperative, postoperative and follow-up time:1,operative time and surgical blood loss; 2 injured vertebral height restoration of vertebral body edge; 3,Cobb angle correction; 4, nerve damage repair level.Results:1.The non-bone graft group and the bone graft group operative time and blood loss volume, the difference between the two groups, bone slightly longer operative time, blood loss, a little more, after treatment were statistically significant (P>0.05).2. In the anterior vertebral height restoration aspects. Postoperative and follow-up, compared to the correction of high loss, bone graft group than non-bone graft group, the difference was statistically significant (P<0.05).3.Cobb angle correction in the area. Postoperative and follow-up, compared to the correction of Cobb angle loss, bone graft group than non-bone graft group, the difference was statistically significant (P<0.05).4. In the nerve injury repair situations. Preoperative and follow-up, compared (P=0.245), the difference was not statistically significant (P>0.05).Conclusions:1.The spinal vertebrae body grafting for treatment of thoracolumbar burst fracture which contain vertebral height and Cobb angle, is superior to non-fusion group.2.The spinal vertebrae body grafting for treatment of thoracolumbar burst fracture, can increase the former, the stability in the column, after long-term prevention of the occurrence of vertebral collapse, improving the efficacy. |
