Variation in Formation of Lateral Femoral Cutaneous Nerve – A Case Study

Abstract

Aims and Objectives: The lateral femoral cutaneous nerve is a purely sensory nerve and originates from the upper lumbar roots (L2, L3).The aim of this study is to identify the variation in formation of lateral femoral cutaneous nerve. Materials and Methods:The study was performed on 25 cadavers (50 body-sides) and the variation in formation of lateral femoral cutaneous nerve was observed. Results: In 20 specimens out of 50 specimens, the lateral femoral cutaneous nerve was formed by L2 & L3 (40%). The lateral femoral cutaneous nerve was formed by L1 & L2 in 16 specimens out of 50 specimens (32%). In 14 specimens out of 50 specimens, the lateral femoral cutaneous nerve was absent (28%). Conclusion:The lateral femoral cutaneous nerve and its variations are important to consider especially during inguinal hernia repair, abdominoplasty, and iliac bone grafting.
