Pulsed Radiofrequency Ablation and Steroid Injections for the Treatment of Meralgia Paresthetica

The area where the lateral femoral cutaneous nerve is seen with US will be anesthetized with 1 ml of 1% lidocaine and a 22 Gauge, 10 cm-5 mm RF cannula will be inserted. Sensory fibers will be stimulated with 0.3-0.5 V. Then, motor fibers will be stimulated up to 1.5 V. If no motor contraction is seen, LFCN will be ablated at 42 degrees Celsius for 240 seconds. The procedure will be completed with the injection of 2 ml of 2% lidocaine and 2 ml (8 mg) dexamethasone through the RF cannula.
