Objective: To evaluate the clinical curative effect of thoracolumbar fracture surgery with the pedicle screw system and posterior lumbar interbody fusion. Method: Sixty-seven cases of thoracolumbar fractures were received the posterior internal fixation operation, and divided into two groups, thirty-seven cases with fusion for thoracolumbar burst fractures, thirty cases without fusion for thoracolumbar burst fractures. Results: (1)Compared with the mean anterior body compression preoperative and Cobb's angle, the surgery results were satisfactory(P<0.01). The review results of with fusion for thoracolumbar burst fractures group were significantly better than the control group (100. 65±3. 57) vs. (94. 58±3. 74), (7. 92±2. 53) vs. (10. 10±4. 39), P<0.05. (2)The postoperative VAS score of with fusion for thoracolumbar burst fractures group were better than then other group (6. 7±1. 5) vs. (5. 6±1. 2), P<0.05. Conclusion: The results of treatment of thoracolumbar fracture with the pedicle screw system and posterior lumbar interbody fusion. This procedure can make fracture with satisfactory restoration, prevent the loss of Cobb's angle and promote osseous healing.%目的:评价后路内固定融合术治疗脊柱胸腰段骨折的临床疗效.方法:67例胸腰段骨折患者均行后路内固定手术,分为植骨融合组37例和非植骨融合组30例.结果:①两组患者术后椎体前缘压缩率、Cobb角较术前显著改善(P＜0.01),植骨融合组复查结果显著优于非植骨融合组(100.65±3.57)vs.(94.58±3.74),(7.92±2.53)vs.(10.10±4.39),P＜0.05;②植骨融合组术后腰背疼痛VAS评分改善幅度明显优于非植骨融合组(6.7±1.5)vs.(5.6±1.2),P＜0.05.结论:后路内固定融合术可实现骨折满意复位,恢复椎体高度,减少Cobb角丢失,促进骨性愈合,是治疗胸腰椎骨折的有效方法.
