In this preliminary study, we aimed to investigate the relationship between the lateral femoral cutaneous nerve (LFCN) and certain bony landmarks in 25 formalin-fixed cadavers. We measured the distances between the point where the LFCN emerges from the lateral side of the psoas major (PM) and: (a) the crossing point of the iliac crest (IC) and the PM; (b) the anterior superior iliac spine (ASIS); and (c) the pubic tubercle (PT). We also measured the distances between: the ASIS and the PT (AB distance), the ASIS and the point where LFCN crossed the inguinal ligament (IL) (AC distance); and we calculated the ratio of AC/AB for each side. We found that on 19 sides, the LFCN was distal to the IC, on 13 sides it was at the same level with the IC, and on 12 sides it was proximal to the IC. The (a) was -0.98±5.57 cm; (b) was 12.39±2.67 cm; (c) was 17.76±3.33 cm; AC was 2.95±2.01 cm; and the AC/AB was 0.22±0.16. We suppose that, especially our AC/AB ratio, will be of help in finding the LFCN during surgical procedures at the inguinal region.
