Ultrasound-Guided Pulsed Radiofrequency Treatment for Meralgia Paresthetica

Meralgia paresthetica (MP) is one of the most common mononeuropathies of the lower limb, characterized by injury or compression of the lateral cutaneous femoral nerve at the level of the anterior superior iliac spine and inguinal ligament. Many predisposing factors, such as weight gain, obesity, and restrictive clothing, contribute to the injury of the lateral cutaneous femoral nerve along its course from the pelvis towards the thigh. Although a great number of cases are successfully treated with conservative measures, a subgroup of patients suffer chronic dysesthetic pain with intermittent flare-ups in their lifetime, with a negative impact on quality of life, requiring additional treatment. The purpose of this case report is to describe the successful management of MP with ultrasound-guided pulsed radiofrequency of the lateral cutaneous femoral nerve.
