Description[edit | edit source]
The ilioinguinal nerve is a mixed nerve that originates from the lumbar plexus. It emerges near the outer edge of the psoas major muscle and travels downward through the front of the abdominal wall. It stays beneath the peritoneum and passes in front of the quadratus lumborum muscle, continues downwards and obliquely across its surface, then it passes over the anterior surface of the iliacus muscle until it reaches the iliac crest. From there, it traverses through the transversus abdominis and the internal oblique muscles. As it continues, it becomes visible near the groin area, passing through the superficial inguinal ring just in front of the spermatic cord in males[1].
Root[edit | edit source]
Originate from the anterior rami from L1 nerve roots in the lower back, in some cases it receives contribution from T12 or l2 in other cases upon its origin.
Branches[edit | edit source]
Ilioinguinal nerve gives motor branches to the transversus abdominis and the internal oblique muscles when it passes through the posterior abdominal wall.
After existing though superficial inguinal ring it gives sensor branches; anterior labial nerve in females and anterior scrotal nerve in male
Function[edit | edit source]
Motor[edit | edit source]
The motor innervation to transversus abdominis and the internal oblique muscles
Sensory[edit | edit source]
Anterior labial nerve in females gives cutaneous innervation to anterior one-third of the labium majora, mons pubis, and root of clitoris.
Anterior scrotal nerve in males gives sensory innervation to skin of the anterior 1/3 of the scrotum and the root of the penis
In addition cutaneous innervation to the superior medial thigh.
Clinical relevance[edit | edit source]
Ilioinguinal nerve injuries/ neuropathy frequently occur following abdominal surgery, abdominal wall trauma, accidently during surgery because of traumatic trochar from laparoscopic surgeries, post hysterectomy or during inguinal hernia repairs. However, when the motor branches of the nerve are affected, it can result in weakened transversus abdominis and internal oblique muscles, potentially leading to the development of inguinal hernias[3].
Furthermore, ilioinguinal nerve entrapment may also occur due to the presence of sutures in close proximity, leading to sensory disturbances along the nerve's path, a condition known as nerve entrapment[4].
Ilioinguinal neuralgia one of the common causes for chronic lower abdominal and anterior pelvic pain.
Inguinodynia that is a chronic or persistent groin pain
Assessment[edit | edit source]
Physical Examination
The ilioinguinal nerve usually its manifestation will cause cutaneous manifestation in the nerve distribution without weakness like; sharp or burning sensation that worsening with lifting or bending. Tenderness point may be observed near the ASIS (anterior superior iliac spine), but it's not a definitive diagnostic sign. In addition the patient may adopt a flexed posture while walking or sit with one leg extended to minimize nerve compression in the groin, and activities or movement that involve hip extension may aggravate the symptoms. For confirmation some diagnostic procedures ma be carried out:
Diagnostic ultrasound we can track the nerve when it becomes superficial down to the superficial inguinal ring[5].
Electrodiagnostic study to exclude other causes like; radiculopathy from lumbar or lumbar plexus injury[6].
Treatment[edit | edit source]
Medical Treatment[edit | edit source]
Nerve block: nerve block guided b imaging ultrasound proved to be effective for treatment of ilioinguinal neuralgia and approximately 55–70% showed a beneficial analgesic post-inguinal hernia surgery[7].
NSAIDs, anti-inflammatory, antidepressants, opioids, and antiepileptics[8] for inguinal neuralgia and inguinodynia.
Radiofrequency ablation is effective for long-term pain relief and poses a low risk of neuroma formation.
Physical Therapy Intervention[edit | edit source]
- Transcutaneous electric nerve stimulation, myofascial release, and acupuncture can control symptoms of the ilioinguinal neuralgia.
