A medial branch block helps identify if the small nerves near your facet joints—called medial branches—are causing your back pain. This quick, targeted procedure can confirm whether inflamed or arthritic joints are the problem.
Medial branch blocks are used to determine whether the small nerves connected to the facet joints of the spine are the source of your pain. These nerves, known as the medial branches, can transmit pain signals from inflamed or arthritic joints.
A medial branch block involves injecting a local anesthetic near these nerves. If your pain is relieved, it confirms that the facet joints are likely responsible. This information can guide further treatment such as radiofrequency ablation for longer-lasting relief.
The procedure is quick, performed in an outpatient setting, and requires only local anesthesia. Fluoroscopic (X-ray) guidance ensures that the anesthetic is accurately placed near the targeted nerves.
