PURPOSE
To evaluate the ability of high-frequency sonography to evaluate the lateral femoral cutaneous nerve (LFCN).
METHODS
A cadaveric study was performed on 5 cadavers to outline the normal course of the LFCN. Next, 37 LFCNs in 21 volunteers were evaluated via sonography with a 5-13-MHz linear-array transducer.
RESULTS
The LFCN was easily identified in our dissections. It always entered the thigh under the inguinal ligament and coursed superficially to the sartorius muscle. In 2/10 (20%) cases, anatomical variants were observed. Sonography revealed the LFCN in 26/37 (70%) cases. The relationships of the nerve with the deep circumflex iliac artery, the anterior superior iliac spine, and the sartorius were visualized. Neuromas were observed bilaterally in 1 volunteer.
CONCLUSION
The LFCN can be seen in the groin with the aid of sonography.
目的
评估高频超声评估股外侧皮神经（LFCN）的能力。
方法
对5具尸体进行尸体研究以勾勒出LFCN的正常走行。接下来，使用5-13MHz线性阵列换能器通过超声对21名志愿者的37条LFCN进行评估。
结果
在我们的解剖中LFCN很容易识别。它总是在腹股沟韧带下方进入大腿，并在缝匠肌表面走行。在2/10（20%）的病例中观察到解剖变异。超声在26/37（70%）的病例中显示出LFCN。神经与旋髂深动脉、髂前上棘和缝匠肌的关系清晰可见。在1名志愿者中双侧观察到神经瘤。
结论
借助超声可在腹股沟区看到LFCN。
