髂腰韧带在脊柱外伤CT定位诊断中的价值

The value of iliac ligament in CT localization diagnosis of spinal trauma

目的 :探讨髂腰韧带在脊柱外伤CT定位诊断中的价值。方法 :分析我院因脊柱外伤行CT检查的530例患者的影像资料,观察髂腰韧带的形态、位置及走行,对比脊柱正常序列与移行椎髂腰韧带起源的关系;并分别采用髂腰韧带定位法、腰大肌起点定位法、髂嵴定位法、第12肋定位法等6种方法进行对比定位分析。结果:脊椎序列变异对髂腰韧带的起始位置影响很小,髂腰韧带定位法对脊柱节段判定的准确率高达99.25%,明显高于其他5种定位法(P<0.05)。结论:髂腰韧带位置相对恒定,在脊柱外伤CT定位诊断中具有重要的临床价值,尤其对于椎体及肋骨变异者能够快速、准确定位。

Objective：To study the value of iliac ligament in CT localization diagnosis of spinal trauma. Methods：To analyze the images of 530 patients with CT examination due to spinal trauma in our hospital,to observe the sacroiliac ligament shape, position and direction,to compare the lumbar ligament origin of transitional vertebra and normal spine sequence. Iliac lumbar ligament were used respectively to positioning method,comparing with psoas major starting point positioning method,the orienta-tion of the crest method,the 12th rib positioning method and other six kinds of positioning methods. Results：Spinal sequence variations had little impact on the original position of the ILL,ILL for spinal segment to determine the accuracy of as high as 99.23%,significantly higher than the other five positioning method （P〈0.05）. Conclusion：Iliac waist position is relatively con-stant,ligament in the spinal trauma CT positioning has important clinical value in diagnosis,which can rapid,accurate position-ing,especially for the vertebral body and frame mutation.
