Abstract
Objective To explore the clinical effect of vertebral interbody fusion for the treatment of thoracolumbar burst fracture. Method According to the sequence number of 80 cases of patients with thoracolumbar burst fracture were divided into control group and observation group, 40 cases in each group. The two groups underwent one stage posterior open reduction and short segment ifxation, the observation group with vertebral interbody fusion, control group with posterolateral bone fusion, all patients were followed up for two years, patients were compared between the two groups before and after the operation, and at the last follow-up vertebral Cobb angle and the last follow-up correction loss, preoperative and postoperative Frankel grade, grafting bone and at last follow-up, the degree of the bone fusion. Result There was no signiifcant difference between the two groups in preoperative Cobb angle, immediate postoperative Cobb angle (P > 0.05), but Cobbe angle of immediate postoperative in this group was signiifcantly different with peroprative (P<0.05). At last follow-up before the two groups of patients in this group of patients with Cobb angle difference between the two groups and were signiifcant, and the loss of correction between the two groups was signiifcant difference (P<0.05). The two groups of patients before surgery compared with the preoperative neurological function improved in varying degrees, and observation group was better than control group. Two groups of patients undergoing bone volume difference was not statistically signiifcant (P > 0.05). However, at the last follow-up the rate of bone fusion between the two groups was signiifcant difference (P<0.05). Conclusion Vertebral interbody intervertebral fusion can obtain good stage bony fusion, and is an ideal bone grafting, can be extended and applied;posterolateral bone fusion has a lower bone fusion, and does not accord with human body biomechanical characteristics, clinical should not be used.关键词
