Cluneal Nerve Blocks

Overview

Cluneal Nerve Blocks are indeed X-ray or ultrasound-guided injections used to treat pain of the lower back, buttock, and pelvic ring. The cluneal nerves are a set of nerves that overlap the pelvis and buttock and can become trapped in muscular tissue, leading to areas of pain. These nerve blocks can aid in both the diagnosis and treatment of chronic low back, buttock, and leg pain by targeting and alleviating the pain caused by these trapped nerves.

Conditions treated with Cluneal Nerve Blocks include pain that causes difficulty sitting for long periods, pain starting at the top or along the middle of the hip bone, and a burning sensation in the buttock. These symptoms are often indicative of cluneal nerve-related pain, which can be effectively managed through these nerve block procedures.

Procedure

The procedure typically takes about 15 minutes to perform. During a Cluneal Nerve Block Procedure, your healthcare provider will help position you to ensure the procedure can be completed with the least amount of discomfort. The skin is cleansed with a sterilizing solution (chlorhexidine), and a sterile drape is placed. A local anesthetic medication, typically lidocaine, is given to numb the skin. Next, the needle(s) is directed to the desired location, and a local anesthetic for numbing and/or steroids for reducing inflammation is injected. Throughout the entire procedure, you will be constantly monitored by the physician. After the injection, a small bandage is placed on your skin. You will be given time after the procedure to ensure you feel good and are not experiencing any side effects before leaving the clinic.

What are the risks and side effects?

Risks and side effects of Cluneal Nerve Blocks are generally minimal, and serious complications are rare. However, it’s important to note that every precaution is taken to ensure safety during the procedure. Potential risks may include but are not limited to, a vasovagal response (passing out), new or increased pain, infection, bleeding, permanent skin changes, allergic or unexpected drug reactions with minor or major consequences, and unintended nerve injury.
