Lateral Femoral Cutaneous Nerve

The lateral femoral cutaneous nerve (LFCN) is a purely sensory nerve that originates from the L2 and L3 nerve roots of the lumbar plexus. The LFCN can be compressed along its course, leading to symptoms of paresthesia and neuropathic pain along the anterolateral aspect of the upper thigh, known clinically as meralgia paresthetica. Therapeutic injections can provide temporary relief of these symptoms. Peripheral nerve stimulation (PNS) is a relatively safe and well-tolerated treatment option for management of peripheral neuropathic conditions, with the most common complication relating to lead migration. PNS of the LFCN can provide long-lasting relief of meralgia paresthetica symptoms.
