Middle cluneal nerve entrapment neuropathy/neuralgia (MCN-EN) is a rare and potentially underdiagnosed etiology for chronic low back pain. Symptoms include pain in the buttock and posterior superior iliac spine area that is increased by activity and direct pressure over the area, and is “neuropathic” in nature. Previous case reports describe successful treatment of MCN-EN with nerve block and/or surgical decompression of the MCN. We present a case report detailing the first successful use of radiofrequency nerve ablation in treating MCN-EN.
