Largest branches of the lumbar plexus
What are the two largest branches of the lumbar plexus?
• Obturator nerve (L2, L3, L4) . It leaves the pelvis through the obturator foramen and supplies the adductors of the thigh.
• Femoral nerve (L2, L3, L4) . It exits the pelvis with the femoral artery and supplies the hip flexors and knee extensors. Distally, it continues as the saphenous nerve to supply sensation to the medial anterior knee and medial distal leg, including the medial malleolus
