Abstract

Background: Lateral femoral cutaneous nerve (LFCN) usually passes along the inner surface of the iliac crest and medial to the anterior superior iliac spine (ASIS), Many orthopaedic procedures that are operated around ASIS may cause injuries to the nerve.

Aim of Investigation: To find out normal variation of the nerve in relationship to the ASIS.

Materials and Methods: The study was carried out as a survey research in preserved 40 Thai cadavers. Dissection was performed on both sides. The AS IS was used as the referent point. The distribution of the nerve was dissected from spinal foramens down to iliac crest, ASIS and at about 5 cm below the spine. Distances between the nerve and the iliac crest and ASIS were measured.

Results: Mean distance between iliac crest and the nerve is 4.52 cm. All nerves ran medial to the iliac crest and inferiorly below the ASIS. In all specimens the nerve passed medial to the ASIS.

Conclusions: Most of the specimens revealed classical nerve distribution while 2.5 % had variation in the course of the nerve so that the nerve might be injured during surgical procedure around the anterior part of iliac crest.
