Several anatomical variations of the ilioinguinal nerve branches have been recorded in older studies. Knowledge of these variations is useful for the improvement of peripheral nerve blocks and avoidance of iatrogenic nerve injuries during abdominal surgeries. The purpose of this study is to perform a systematic review of the literature about the anatomical topography and variations of the ilioinguinal nerve.
An extensive search in PubMed, Scopus, and Web of Science electronic databases was conducted by the first author in November 2021, with the use of the PRISMA guidelines. Anatomical or cadaveric studies about the origin, the course, and the distribution of the ilioinguinal nerve were included in this review. Thirty-one cadaveric studies were included for qualitative analysis.
Several anatomical variations of the ilioinguinal nerve were depicted including its general properties, its origin, its branching patterns, its course, its relation to anatomical landmarks, and its termination. Among them, the absence of ilioinguinal nerve ranged from 0% to 35%, its origin from L1 ranged from 65% to 100%, and its isolated emergence from psoas major ranged from 47% to 94.5%. Numerous anatomical variations of the ilioinguinal nerve exist, not commonly cited in classic anatomical textbooks. The branches of the ilioinguinal nerve may be damaged during spinal anesthesia and surgical procedures in the lower abdominal region.
Therefore, a better understanding of the regional anatomy and its variations is of vital importance for the prevention of ilioinguinal nerve injuries.
在早期研究中已记录到髂腹股沟神经分支的几种解剖变异。了解这些变异有助于改进周围神经阻滞，并避免腹部手术期间的医源性神经损伤。本研究的目的是对有关髂腹股沟神经解剖形态和变异的文献进行系统综述。
第一作者于2021年11月依据PRISMA指南，在PubMed、Scopus和科学网电子数据库中进行了广泛检索。本综述纳入了关于髂腹股沟神经起源、走行和分布的解剖学或尸体研究。纳入31项尸体研究进行定性分析。
描述了髂腹股沟神经的几种解剖变异，包括其一般特征、起源、分支模式、走行、与解剖标志的关系及其终末。其中，髂腹股沟神经缺如的比例为0%至35%，起源于L1的比例为65%至100%，单独发自腰大肌的比例为47%至94.5%。髂腹股沟神经存在许多解剖变异，在经典解剖学教科书中未被普遍提及。在下腹部区域的脊髓麻醉和外科手术过程中，髂腹股沟神经的分支可能会受到损伤。
因此，更好地了解区域解剖及其变异对于预防髂腹股沟神经损伤至关重要。
