Variation in the Cutaneous Branch of Femoral Nerve

Understanding the regional anatomy and variations of femoral nerve -as highly essential in daily life activities- is important for surgeons, orthopaedicians, and anesthetists. It helps to prevent iatrogenic femoral nerve palsy in clinical practices. During the dissection of the right lower limb of the cadaver of a 35 years old male, we observed one additional cutaneous branch separated from the posterior division of the femoral nerve. This branch crossed with femoral artery at the beginning and continued to descend into the medial side of the thigh medial to Gracilis muscle. At the end, it pierced through the deep fascia near the knee joint.
