摘　　要：目的探讨髂嵴间线作为腰椎水平定位标志的可靠性。方法择期在全身麻醉下行脊柱手术患者123名,健康志愿者28名,分别在屈髋俯卧位、侧卧位触诊确定两髂嵴最高点,用顿头金属细针标记,在C型臂下评估并比较其连线及两髂嵴最高点连线所经腰椎水平的位置。结果触诊确定的髂嵴间线位于L3椎体上缘至L5椎体下缘,C型臂下髂嵴间线位于L3-4椎间隙至L5-S1椎间隙水平,触诊确定的髂嵴间线比C型臂下髂嵴间线高1/3椎体至1个椎体1个椎间隙(P<0.05)。结论髂嵴间线分布范围较广,不能准确辨认其位置,作为确定腰椎水平的定位标志具有一定局限性。[Objective] To investigate reliability of intercristal line as landmark for assessing lumbar vertebral level. [Methods] 123 patients, scheduled for spine operation under general anesthesia and 28 healthy volunteers were enrolled, the uppermost point of iliac crests were identified by palpation and marked with metal needles in prone position with hip flexed and in lateral position respectively, then the position of the line connecting its and that connecting the uppermost point of iliae crests were assessed by mobile X-ray system and compared. [ Results ] The palpated intercristal line lay between the level of L3 upper and L5 lower, the imaged intercristal line between the level of L3-4 and L5-S1 inter-space, and the former was higher than the latter from one third of vertebral body to one vertebral body and inter-space（P 〈0.05 ）. [ Conclusions] The position of intercristal line varied too widely to be identified accurately, so the line was insufficient to use as landmark for assessing lumbar vertebral level.
