【摘要】：目的提供高效、准确的股外侧皮神经超声探测的方法,并评估其解剖变异。方法以阔筋膜张肌和缝匠肌之间的间隙作为股外侧皮神经声像图定位标志,18 MHz超声探测150例志愿者的股外侧皮神经。测量神经与髂前上棘之间的距离,观察腹股沟韧带水平的神经分支数目和神经与腹股沟韧带之间的关系,并记录探查时间。结果所有受检者的股外侧皮神经在阔筋膜张肌和缝匠肌之间的肌间隙均清晰显示。股外侧皮神经与髂前上棘之间的平均距离为(15.4±4.1)mm。其中252条神经走行于腹股沟韧带的深面,此水平的神经由1~4根分支组成。鉴别一条神经的平均时间为7s。结论以阔筋膜张肌和缝匠肌的间隙作为声像图定位标志,有助于超声高效,准确地显示股外侧皮神经,超声可观察其解剖学变异。
[Abstract]:Objective to provide an effective and accurate method for ultrasonic detection of lateral femoral cutaneous nerve and to evaluate its anatomic variation. Methods the gap between the tensor lata muscle and the sartorius muscle was used as the location marker of the lateral femoral cutaneous nerve. 18 MHz ultrasound was used to detect the lateral femoral cutaneous nerve in 150 volunteers. The distance between the nerve and the anterior superior iliac spine was measured. The number of nerve branches at inguinal ligament level and the relationship between nerve and inguinal ligament were observed. Results the space of lateral femoral cutaneous nerve between tensor lata muscle and sartorius muscle was clearly displayed. The average distance between the lateral femoral cutaneous nerve and the anterior superior iliac spine was (. Among them, 252 nerves were located on the deep surface of the inguinal ligament. The nerve at this level is composed of 1 or 4 branches. The average time for distinguishing a nerve is 7 s.Conclusion the gap between the tensor lata and the sartorius muscle is used as a sonographic localization marker, which is helpful to the high efficiency of ultrasound. The anatomical variation of lateral femoral cutaneous nerve can be observed by ultrasound.

【正文快照】： 股外侧皮神经(lateral femoral cutaneous nerve,LFCN)发自腰丛,于髂前上棘内侧穿腹股沟韧带的外侧部的深面至股部。LFCN损伤是引起大腿外侧神经功能障碍的常见原因。由于LFCN存在解剖学变异,也常存在医源性损伤[1]。国外文献报道的LFCN的超声显像方法主要用于超声引导下的神
