Ilioinguinal neuralgia is one of the most common causes of lower abdominal and pelvic pain. VA Service Connection for Nerve Damage Mummenthaleret al. The ilioinguinal nerve originates from the L1 nerve root along with the iliohypogastric nerve. Aetiology. Thoracic Paravertebral Block: 5. Ilioinguinal Approach! The ilioinguinal nerve, in general, provides sensation to the upper portion of the skin of the inner thigh, and in men, the root of the penis and upper scrotum, and in women, portions of the pubic area. ilioinguinal nerve entrapment syndrome is an abdominal muscular pain syndrome, characterized by the clinical triad of muscular . The ilioinguinal nerve is comprised of fibers from the L1 nerve root with a contribution of fibers from the T12 nerve root in approximately 25% of patients [4]. 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. It is normally encountered during open repair of inguinal hernia. Selective Nerve Root Blocks. Impingement of a nerve between the L5 and S1 vertebrae indicates the structure is placing pressure on the nerve root. A selective nerve root block can be used for diagnostic or therapeutic treatment of low back or leg pain. 1 Penetrates the transversus abdominis at the anterior superior iliac spine and terminates in the ilium. In this case, the median nerve (i.e., the nerve that originates in the lower back and travels down the back of the thigh finally ending in the foot) is damaged thereby causing pain, tingling sensations, and potentially foot drop (i.e., difficulty lifting the front part of the foot). . Generally, the entire procedure takes just 15 minutes, and we often use a local anesthetic, which removes any sensation you may feel from our inserting a needle. Selective nerve root blocks have been described in a case series as an effective method to alleviate pain from ilioinguinal neuralgia. If the nerve is affected it can cause pain or numbness in these areas. According to the Laser Spine Institute, this is one of the most common of all pinched nerves. References Bradshaw, C., P. McCrory, et al. The genitofemoral nerve originates from the upper L1-2 segments of the lumbar plexus.It passes downwards, pierces the psoas major and emerges from its anterior surface. Abstract Ilioinguinal nerve entrapment is a common cause of groin or inguinal area pain. Branch of the L1 nerve root with a contribution from T12 in some patients. It is a mixed nerve providing motor supply to the Internal Oblique and Transversus Abdominis muscles, and sensory supply to the anterior one third of the scrotum/labia and root of the penis/clitoris, as well as to the superior medial thigh. The ilioinguinal nerve is composed of L1-L2 nerve roots and passes though the psoas muscle while innervating abdominal musculature, the groin, medial thigh, and out to the iliac crest. The ilioinguinal nerve block is used to treat groin pain, often after hernia surgery or trauma to the groin. Its main symptoms include burning pain and numbness over the lower abdomen that radiates to the genitalia and into the inner thigh. It comes through the psoas major's (a spine stabilising muscle) lateral border, just under the iliohypogastric, and passes across the quadratus lumborum and iliacus in the hip rotator muscles. The condition is frequently underdiagnosed leading to controversies regarding its epidemiology and to an intense debate in the literature. When combined with iliohypogastric and genitofemoral nerve block, ilioinguinal nerve block . The ilioinguinal nerve is a continuation of the anterior ramus of spinal nerve L1.

Ilioinguinal nerve block has shown great utility as a diagnostic, prognostic, and therapeutic maneuver in the evaluation and treatment of groin and genital pain that is thought to be mediated via the ilioinguinal nerve. Transversus Abdominis Plane (TAP) Block: 11. In a study of 100 embalmed cadavers, the ilioinguinal nerve originated from L1 in 130 specimens (65%), from T12 and L1 in 28 (14%), from L1 and L2 in 22 (11%), and from L2 and L3 in 20 (10%). 24.1) also originates from the L1 nerve root and is found inferior to the iliohypogastric nerve, perforating the transversus abdominis muscle at the level of the iliac crest running medially in a deeper plane than the iliohypogastric nerve. Both the iliohypogastric and ilioinguinal nerves emanate from the first lumbar spinal root. The main complaints in obturator nerve entrapment include difficulty with ambulation and the development of an unstable leg. using code 64640, Destruction by neurolytic agent; other peripheral nerve or branch. .
