il·i·o·in·gui·nal nerve

[TA]
terminal branch, with the iliohypogastric nerve, the first lumbar nerve, passes through the inguinal canal and superficial inguinal ring to supply the skin of the upper medial thigh, mons pubis, and scrotum or labia majora.
Synonym(s): nervus ilioinguinalis [TA]

ilioinguinal nerve

a nerve that provides cutaneous innervation to the upper medial thigh, the root of the penis and the anterior surface of the scrotum in men, or the mons pubis and labia majora in women. Through its course, it also supplies branches to the abdominal musculature.

(il'ē-ō-ing'gwi-năl nĕrv) [TA]
Arises from the first lumbar nerve, passes through the inguinal canal and superficial inguinal ring to supply the skin of the upper medial thigh, mons pubis, and scrotum or labium majus.
Synonym(s): nervus ilioinguinalis [TA] .

ilioinguinal nerve

A sensory nerve originating in the lumbar plexus and composed of axons from spinal cord segment L1. It runs with the spermatic cord (in males) or the round ligament (in females) through the internal inguinal ring to the skin of the scrotum or labium majus. It innervates the skin of the proximal and medial thigh and of the scrotum or labium majus.

These include the intercostal nerves (T7-T11), the subcostal nerve (T12), and the iliohypogastric and ilioinguinal nerves (L1).
The ilioinguinal nerve (L1) communicates with the iliohypogastric nerve between the internal oblique and transversus abdominis near the anterior part of the iliac crest.
The iliohypogastric and ilioinguinal nerves are also at risk for injury with laterally placed trocars through direct trauma or nerve entrapment.
Nerves that respond well to freezing include the ilioinguinal nerves, intercostal nerves and superficial femoral nerves.
The goal of orchiectomy is to relieve orchialgia by releasing the entrapped ipsilateral genitofemoral and/or ilioinguinal nerves.
The nerve supply to these muscles is derived from the lower thoracic nerves, via the lower intercostal, subcostal, iliohypogastric and ilioinguinal nerves (2).
It is possible to selectively block the subcostal, iliohypogastric and ilioinguinal nerves where they lie between the tranversus abdominus and internal oblique muscles, by performing a transversus abdominus plane (TAP) block (3).
Knowledge of the variations in the course of the iliohypogastric and ilioinguinal nerves is of practical clinical importance.

They proposed and showed that a higher approach (1 cm cephalad to the ligament), aiming to block femoral, obturator, lateral femoral cutaneous as well as the higher iliohypogastric and ilioinguinal nerves, gave better analgesia, as evidenced by reduced morphine consumption at 12 and 24 hours, compared with femoral nerve block.
