The purpose of this study was to map the course of the ilioinguinal and iliohypogastric nerves.
The courses of iliohypogastric and ilioinguinal nerves from 11 fresh frozen cadavers were mapped from their lateral emergence on the anterior abdominal wall to their midline termination in reference to fixed bony landmarks. Bivariate fit ellipses were generated for each nerve and compared with sites of standard abdominal surgical incisions.
Thirteen iliohypogastric and 16 ilioinguinal nerves were identified and mapped. On average, the proximal end of the ilioinguinal nerve entered the abdominal wall 3.1 cm medial and 3.7 cm inferior to the anterior superior iliac spine, then followed a linear course to terminate 2.7 cm lateral to the midline and 1.7 cm superior to pubic symphysis. The iliohypogastric nerve entered the abdominal wall on average 2.1 cm medial and 0.9 cm inferior to the anterior superior iliac spine, which followed a linear course to terminate 3.7 cm lateral to the midline and 5.2 cm superior to pubic symphysis.
Abdominal wall surgical sites below the level of the anterior superior iliac spine have the potential for ilioinguinal or iliohypogastric injury.
本研究旨在描绘髂腹股沟神经和髂腹下神经的走行。
以固定的骨性标志为参照，描绘11具新鲜冷冻尸体的髂腹下神经和髂腹股沟神经从腹壁外侧发出至中线终末的走行。为每条神经生成双变量拟合椭圆，并与标准腹部手术切口部位进行比较。
共识别并描绘了13条髂腹下神经和16条髂腹股沟神经。平均而言，髂腹股沟神经近端在髂前上棘内侧3.1 cm、下方3.7 cm处进入腹壁，然后呈直线走行，在中线外侧2.7 cm、耻骨联合上方1.7 cm处终末。髂腹下神经平均在髂前上棘内侧2.1 cm、下方0.9 cm处进入腹壁，呈直线走行，在中线外侧3.7 cm、耻骨联合上方5.2 cm处终末。
髂前上棘水平以下的腹壁手术部位有损伤髂腹股沟神经或髂腹下神经的可能。
