Lateral Femoral Cutaneous Nerve
The lateral femoral cutaneous nerve is a pure sensory nerve that arises from the L2 and L3 spinal nerve roots. It is susceptible to compression as it courses along the abdominal wall deep to the inguinal ligament and into the subcutaneous tissue of the thigh. Meralgia paresthetica is used to describe the clinical syndrome of pain, burning, numbness, and paresthesia in the anterolateral thigh associated with compression of this nerve. Most of the patients respond to conservative management including nerve block. Ultrasound-guided technique to inject local anesthetic and steroids has been described with high accuracy and efficacy to provide pain relief.
