椎弓根螺钉内固定系统治疗胸腰椎骨折

目的探讨新型椎弓根螺钉内固定系统（钉．棒内固定系统）治疗胸腰椎骨折的临床疗效。方法选取胸腰椎骨折患者68例，应用新型短节段椎弓根螺钉内固定系统治疗，观察其临床疗效。结果经6-18个月的随访，平均12个月，椎体前缘术前平均高度为47％，术后平均高度为94％；后缘术前平均高度为76％，术后为97％，手术前后差异有统计学意义（P〈0．01）。68例经短节段椎弓根螺钉内固定系统内固定后效果较好，18例早期手术效果尤为满意，41例神经功能障碍中除4例无恢复外，其余均有不同程度的恢复。结论胸腰椎骨折应早期手术治疗，钉一棒固定系统治疗效果显著，规范的手术操作至关重要，还要注意其禁忌证。

Clinical effect of new type of short section pedicle of vertebral arch nail system on patients with thoracolumbar fracture

Objective To explore the clinical effect of one new type of short section pedicle of vertebral arch nail system(internal fixation system by nail-stick) on patients with thoracolumbar fracture.Methods 68 patients with thoracolumbar fracture were selected.Internal fixation system by nail-stick was used on the patients with thoracolumbar fracture,the clinical effect was observed.Results After following up for six to eighteen months,the vertebral height was measured by X-ray.The anterior edge height of the vertebral was 47% before operation and 94% after operation,the posterior edge height of the vertebral was 76% before operation and 97% after operation,there was significant difference between preoperation and post operation(P<0.01).All the cases with AF intemal fixation system had better clinical effect,18 cases had satisfactory effect.Except that the neurological deficits of 4 cases had not been improved,those of the other cases all had been impreved at some degree.Conclusion Thoracolumbar fracture should be treated early,AF imtermal fixation system has significant effect on the thoracolumbar fracture,the skilled performance is important during the operation,and contraindications of internal fixation system by nail-stick should be noticed.
