Genitofemoral Nerve Block
Genitofemoral Nerve Block
A genitofemoral nerve block is a targeted injection used when the clinical history, examination, and pain distribution suggest genitofemoral neuralgia or another focal neuropathic groin pain syndrome. Common contexts include selected postsurgical or post-traumatic groin pain.
The block usually contains local anesthetic, with corticosteroid used selectively. Ultrasound or fluoroscopic guidance may be used depending on the target and anatomy. The procedure can provide temporary therapeutic relief and diagnostic information, but published evidence is more limited than for many spine interventions.
Risks and Expectations
Response varies. Potential risks include bruising, bleeding, infection, medication reaction, temporary numbness, nerve irritation or injury, and injury to nearby vessels or structures.
Clinical Evidence, Limitations & Patient Selection
Genitofemoral block is a diagnosis-specific diagnostic/therapeutic procedure for selected genitofemoral neuralgia and postsurgical/post-traumatic neuropathic groin pain.
Important limitation: Evidence is modest and relief is often temporary; broad promises of immediate or durable relief are not appropriate.
Every procedure has potential risks, and individual benefit cannot be guaranteed. Recommendations at Solutions in Pain are based on the diagnosis, examination, relevant imaging, prior treatment, medical history, medications, patient goals, current evidence, and applicable payer requirements.
