SELECTIVE EPIDURAL INJECTIONS
Chronic spinal pain can significantly impair one’s quality of life. For patients experiencing severe discomfort, a Selective Nerve Root Block (SNRB)—also referred to as a transforaminal epidural steroid injection—offers a sophisticated approach to pain management. Originally utilized as a diagnostic tool, this procedure has been refined to provide targeted therapeutic relief for chronic inflammatory conditions.
Unlike standard corticosteroid injections, a selective epidural is precisely administered near specific spinal nerve roots. The spinal column functions as a complex neural pathway where individual nerves exit the vertebrae through small bony openings known as foramen. By delivering medication directly into these foraminal spaces, clinicians can address the exact source of neural irritation, making this a more specialized and delicate procedure than a systemic injection.

WHAT WILL A SELECTIVE EPIDURAL OR SNRB TREAT?
A selective epidural is an effective intervention for various musculoskeletal and neurological conditions, including:
spinal nerve pain relief
Treatment Procedure for SNBR
The process begins with a comprehensive clinical evaluation, including a review of your medical history and current pharmacological regimen. To ensure patient comfort, a local anesthetic or mild sedation may be administered. During the procedure, the patient is typically positioned on a specialized X-ray table to facilitate real-time imaging.
Utilizing fluoroscopic guidance (live X-ray) or computed tomography, the physician precisely directs a needle toward the symptomatic nerve root within the foramen. A contrast agent is injected to verify exact placement. Once confirmed, a solution containing a local anesthetic (lidocaine) and a long-acting corticosteroid is administered to suppress inflammation and interrupt pain signaling.
The procedure generally concludes within 60 minutes. While individual results vary, patients often experience significant pain reduction within three to seven days. The therapeutic effects typically persist for several months, though the duration of relief is dependent on the patient's unique pathology.
Note: Due to potential temporary numbness or localized weakness following the injection, patients are required to arrange for a companion or professional transport service for their return home.

SELECTIVE EPIDURAL SIDE EFFECTS
While selective epidural injections are generally considered safe, it is important to be aware of potential risks and adverse reactions. These may include:
Selective epidurals are primarily intended for acute or sub-acute relief rather than indefinite use. Because repeated corticosteroid exposure can potentially impact tissue integrity or endocrine function, treatments are generally limited to three injections within a six-month period.
For many patients, the potential for restored mobility and relief from debilitating pain far outweighs these clinical risks. If chronic pain is limiting your daily function, an SNRB may be a vital component of your recovery plan.
