I am planning for a LFC nerve block, but have heard it’s better to block where the compression occurs. Do you have have any literature as to where the best location to block would be? Thank you

Ultrasound-Guided Lateral Femoral Cutaneous Nerve Block - NYSORA

The lateral femoral cutaneous nerve (LFCN) divides into several branches innervating the lateral and anterior aspects of the thigh.Indications are postoperative analgesia for hip surgery, meralgia paresthetica, and muscle biopsy of the proximal lateral thigh.

I love NYSORA but if you're trying to find the compression, you'll want to start your scan higher at the ASIS and slide down as it's most at risk at the inguinal ligament level was the old teaching.

Sonographic features of the lateral femoral cutaneous nerve in meralgia paresthetica - PMC

The diagnosis of meralgia paresthetica (MP) is usually based on clinical symptoms and physical examination. Therefore, the present study aimed to investigate the lateral femoral cutaneous nerve (LFCN) sonographic features in MP patients. A total of ...

Ultrasound-Guided Diagnosis and Treatment of Meralgia Paresthetica - PubMed

Meralgia paresthetica refers to the entrapment of the lateral femoral cutaneous nerve at the level of the inguinal ligament. The lateral femoral cutaneous nerve - a purely sensory nerve - arises from the L2 and L3 spinal nerve roots, travels downward lateral to the psoas muscle, and then crosses...

It's an easy PNS case if you're into that.

it's easier to find at the fat filled tunnel between TFL and sartorious and track it up than start high and trace down.

spoke to a lady today who I did this block/hydrodissection on 2 months ago, after experiencing the issue for 6 months (she gained a bunch of weight but wore the same clothes...) about 10 ml injected once i found the nerve and tracked it up under the inguinal ligament.

she hasn't experienced the pain since the block.
