They pass together laterally through the psoas muscle, extend diagonally along the ventral surface of the quadratus lumborum muscle above the iliac crest. Prognostic nerve blocks: These are used to help your physician predict the effectiveness and outcome of a given treatment. The ilioinguinal nerve is a division of the LI nerve root with a support via T12 in some patients. The ilioinguinal nerve block is performed by placing the patient in the supine position with a pillow under the knees, if lying with the legs extended increases the patient's pain due to traction on the nerve. Then it travels with other structures in the inguinal canal to supply the skin at the inner groin and the base of the penis or labia. Abstract Ilioinguinal nerve entrapment is a common cause of groin or inguinal area pain. The ilioinguinal nerve originates at the L1 and T12 nerve roots and extends through the lateral psoas muscle. The disorder is characterized by sharp, shooting pain originating at the anterior superior iliac spine and radiating to the groin. The nerve divides into two branches, the genital branch and the lumboinguinal nerve also known as the femoral branch, both of which then continue downwards and medially to the inguinal and femoral canal respectively.
