FAQ’s on Medial Branch Block

What is a Medial Branch Block?

Medial Branch Block DenverThe medial nerve branches are small extensions of a regular nerve that ‘branch’ off from the main nerve root. These branches provide sensation to the spinal joints and the joint capsule. They have no motor function at all.

Facet joints are small bones – normally only the size of a thumbnail –that are located on each side of the spine and assist in providing mobility. These small joints are what allow the vertebrae to flex and bend in a functional manner, with the medial nerve branches serving to provide a nervous connection to them.

How is a Medial Branch Block performed?

There are two separate reasons the MBB procedure is performed. The first is as a diagnostic test to see if the facet joint is the actual cause for the pain. The second is as a therapeutic block for providing relief. The procedure is performed the same way for either reason, and usually the procedure serves both purposes.

To perform either of the blocks, the patient will be placed in the prone position to provide the Denver pain management doctor ready access to the spine. The area to be used as an injection site will be sterilized and numbed, with the injection of the needle guided by fluoroscopy.

Fluoroscopy is an imaging technique involving the use of repeated X-rays to create a current image of the needle within the patient, and through this the physician is able to ensure accuracy. Once the needle has been seated into the area around the medial branches, contrast dye is injected to ensure accuracy.
