摘要
目的:为骨盆手术防止股外侧皮神经盆内段损伤提供解剖学基础。方法:在25具成人防腐标本上解剖观察股外侧皮神经的起源、行程及分支,测量神经出盆点与髂前上棘中心点的距离。结果:①股外侧皮神经出盆点位置的解剖变异较大,根据神经出盆点与髂前上棘的关系可分为四种类型。②股外侧皮神经72％从腹股沟韧带深面穿出,28％穿行于腹股沟韧带中。穿出点距髂前上棘的距离为(1.02±0.88)cm。③股外侧皮神经穿过腹股沟韧带并被阔筋膜包裹,形成了股外侧皮神经的远侧固定点。结论:(1)腹股沟韧带及阔筋膜对股外侧皮神经的固定作用是骨盆手术损伤股外侧皮神经的解剖学因素。(2)术中神经预防性松解是避免医源性神经损伤的关键。
Objectives: To provide applied anatomic data for preventing lateral femoral cutaneous nerve (LFCN) injury in pelvic operation and to develope the protocol to diminish the possibility of this kind of iat-rogenic injury. Methods: The pelvic segments of LFCN were dissected in 25 embalmed adult cadaveric specimens. The sources, courses and branches of the nerve were observed and more attention was focused on the site where the nerve leaving the pelvis to the thigh. The distance between the point of its exit and the center of the anterior superior iliac spine was measured. Results: ①The exact point where the LFCN exited the pelvis was subject to more variation. LFCN could be defined as four types according to the relationship between its site of exit and the anterior superior lilac spine. ②LFCN exited the pelvis to the thigh under or through the inguinal ligament and the distance between the point of its exit and the anterior superior iliac spine was 1. 02±0. 88 cm.③LFCN passed within the substance of the inguinal ligament and en-sheathed in the fascia lata, thus a distal fixed area of LFCN was formed. Conclusion: LFCN immobilization by the inguinal ligament and fascia lata is the anatomic basis of the nerve injury. Avoidance of the iatrogenic injury to LFCN should focus on the general understanding of the nerve anatomy and the neurolysis in operation.
