Ilioinguinal Nerve Block

  • Tatsuo NakamotoEmail author


The ilioinguinal/iliohypogastric nerve (II/IH), one of the branches of the lumbar plexus, includes the L1 (partially Th12) root. Ultrasound-guided II/IH block is performed by medial-to-lateral in-plane insertion and interfascial injection while identifying the II/IH between the fascia of the internal oblique muscle (IOM) and transversus abdominis muscle (TAM) in the region medial to the anterior superior iliac spine (ASIS).
