The Lateral Femoral Cutaneous Nerve Block

What is the lateral femoral cutaneous nerve? And why are lateral femoral cutaneous nerve blocks helpful? The lateral femoral cutaneous nerve, in general, provides sensation to the outer and frontal side of the thigh just above the greater trochanter to the knee. The pain is made worse when sitting or squatting for long periods. This pain may occur secondary to compression of the nerve by wide belts or tool pouches. The lateral femoral cutaneous nerve block is useful in the evaluation and management of lateral thigh pain. Lateral femoral cutaneous nerve block with local anesthetic and steroids is useful in the treatment of persistent pain thought to be secondary to inflammation or entrapment of the lateral femoral cutaneous nerve.
