目的:研究经后路复位内固定并行伤椎植骨对胸、腰椎骨折的治疗效果.方法:对椎体压缩性骨折和爆裂性骨折使用AF或钉棒系统复位固定后,经伤椎椎弓根向伤椎植入自固化磷酸钙人工骨和同种异体骨的治疗结果进行分析.结果:治疗432例 468椎,手术后椎体高度即刻恢复100%的319椎;95%以上80椎;90%以上60椎;80%以上的9椎.398例获得随访,随访10月～8年,伤椎均获得骨性愈合,脊柱稳定性及运动功能恢复良好.结论:胸、腰椎椎体骨折经AF或钉棒系统复位固定后,伤椎植入自固化磷酸钙人工骨和同种异体骨的疗效确切,效果优良.%Objective:To investigate the effect of two different internal fixation system and bone graft on patients with thoracic or lumbar spinal fracture. Methods: From April,2001 to June,2008, 468 body of vertebral in 432 patients suffered from compression fracture or blowout fracture were randomly selected to be treated with AF fixation system and screw - baculum fixation system, then artificial bone of calcium acid phosphate and homogeneity bone were transplanted into the vertebral body of fracture through neck of vertebra. Postoperatively, radiographic finding and clinical results were observed. Results: Instantly after operation, the height of 319 vertebral body were recovered completely ( 100％ ), 80 recovered 95％, 60 recovered 90％ and 9 recovered 80％. A total of 398 patients were followed - up after surgery, ranging from 10 months to 8 years. Radiographs showed all patients have got the bone union, the movement function of spine was significantly relieved and none suffered from low back pain or radicular pain. Neither complications nor instrumentation failure were observed. Conclusion:Internal fixation system and transplantation of bone graft through neck of vertebra could be recommended for treatment of thoracic or lumbar spinal fracture.
