Abstract

The knowledge of anatomic variation in the division of the femoral nerve is important for the anesthetists as well as the surgeons to ensure a complete femoral nerve block and conduct a successful surgery. We report a rare case of higher division of femoral nerve 3.5 cm proximal to the inguinal ligament intervened by an accessory iliacus muscle. Aberrant slips of iliacus either by splitting or covering the femoral nerve may act as potential factor in femoral nerve compression, as in this case. The anterior and posterior divisions of femoral nerve continued deep to the inguinal ligament, separated by accessory iliacus, and presented an unusual communication in between them in the upper thigh. To our knowledge, the present case of higher branching pattern of femoral nerve well above the inguinal ligament is rather rare and clinically significant.
