目的分析椎弓根螺钉在胸腰椎骨折中的临床应用及疗效。方法采用3种椎弓根螺钉系统治疗35例，随访6个月～4年，平均2年。结果伤椎前缘平均高度由术前42%提高到术后93.5%，后缘由术前94%提高到术后98%，后凸角由术前27.6°降低到术后5.2°，椎管面积从术前69%提高到术后95%；神经功能按Frankel分级标准，较术前改善Ⅱ级以上。结论椎弓根螺钉系统内固定是治疗胸腰段脊柱损伤的有效方法之一。

Objective　To analyze curative effect and surgical treatment for pedicle screw in thoracolumbar fracture. Methods　35 patients were treated by 3 types of pedicle screw system. The patients were followed up for 2 years on average,ranging from 6 months to 4 years. Results　Average height of front vertebra was corrected from 42% before operation to 93.5% after operation. The average height of back vertebra was restored to 98% after operation(94% before operation). The angle of kyphosis was corrected from 27.6° before operation to 5.2° after operation. The area of spinal canal was restored to 95% after operation(69% before operation).Nerve injuries were improved more than Ⅱ levels with Frankel's standard. Conclusion　The internal fixation of pedicle screw is an effective treatment of the thoracolumbar fracture and spinal cord injuries.
