Selective Nerve Root Block (SNRB): A Precise Diagnostic and Therapeutic Procedure for Sciatica
Sciatica and nerve-related leg pain can significantly affect daily activities and quality of life. One of the most accurate methods to identify the exact nerve causing pain is a Selective Nerve Root Block (SNRB). This minimally invasive procedure involves injecting a local anesthetic around a specific spinal nerve root under imaging guidance. If the patient's pain is temporarily relieved after the injection, it confirms that the targeted nerve is the source of the symptoms. This information helps orthopedic surgeons and spine specialists plan the most effective treatment, whether conservative management or surgery.
How is a Selective Nerve Root Block Performed?
The procedure is usually performed as a day-care treatment under fluoroscopic (X-ray) guidance. After cleaning and sterilizing the skin, a local anesthetic is used to numb the area. A thin needle is then carefully advanced near the suspected nerve root using real-time imaging. Contrast dye may be injected to verify accurate needle placement. Once confirmed, a combination of local anesthetic and, in some cases, a corticosteroid medication is administered around the nerve. The procedure generally takes 20–30 minutes, and most patients can return home shortly afterward. Besides helping identify the painful nerve, the injection may also provide temporary or even prolonged relief from symptoms.
