摘要
目的 :探索胸腰段椎管内骨折块对脊髓损伤的影响程度 ,确定脊髓受压的临界椎管狭窄率 ,为临床治疗的选择提供参考标准。方法 :对 12 1例不稳定性胸腰椎骨折进行改良Frankel分级法脊髓功能评估和CT椎管面积测量 ,作统计学分析。结果 :5 6例有不同程度的脊髓功能损伤 ,其截瘫程度与椎管内骨块占位显著相关 ,相关程度以T12最高 ,L2最低。脊髓受压的椎管占位临界值为T12 30 % ,T1135 % ,L140 % ,L2 5 5 %。结论 :胸腰段椎管内骨块占位程度与脊髓损伤有显著相关性。
Objective:To study the relationship between bone displacement and the seriousness of spinal cord of thoracolumbar fractures.Method:121 cases were studied and the improved Frankel evaluation way was employed to determine the spinal cord function. The intra spinal canal fractured bone chip was measured on CT images.Result:56 of 121 cases were paraplegia from uncomplete to complete and the degree of paraplegia were positive relationship between displacement in vertebral canal and SCI seriousness.The sequence followed as: T12>T11>L1>L2.According to statistic calculations, the critical value of displacement were: T12 30%,T11 35%, L1 40%, L2 55%.Conclusion:There was a positive relationship between displacement in vertebral canal and SCI seriousness.
