This report reviews the topographical and functional anatomy relevant for assessing whether or not the obturator nerve (ON) can be anesthetized using a fascia iliaca compartment (FIC) block. The ON does not cross the FIC. This means that the ON would only be blocked by an FIC block if the injectate spreads to the ON outside of the FIC. Such a phenomena would require the creation of one or more artificial passageways to the ON in the retro-psoas compartment or the retroperitoneal compartment by disrupting the normal anatomical integrity of the FI. Due to this requirement for an artificial pathway, an FIC block probably does not block the ON.
本报告回顾了与评估闭孔神经（ON）是否可通过股前筋膜间隙（FIC）阻滞来麻醉相关的局部解剖和功能解剖。ON 不穿过 FIC。这意味着只有当注射物扩散到 FIC 外的 ON 时，FIC 阻滞才会阻断 ON。这种现象需要通过破坏 FI 的正常解剖完整性，在腰大肌后间隙或腹膜后间隙中为 ON 创建一个或多个人工通道来实现。由于需要这种人工通道，因此 FIC 阻滞可能无法阻断 ON。
