A cluneal nerve block is a minimally invasive procedure used to treat people with lower lumbar pain that radiates to the upper portion of the buttocks.
Prior to the procedure, you will be asked to lie face down on the table. The patient’s skin is cleaned and prepped for the injection.
A long-lasting steroid medication is then injected into the affected cluneal nerve area. During the injection, the doctor uses a special real-time x-ray, known as a fluoroscope, to guide the needle. This helps deliver the steroid medication as closely as possible to the aggravated and inflamed nerve root. The procedure takes approximately fifteen minutes.
