Selective Nerve Root Blocks

Selective Nerve Root Blocks (SNRBs) are both a diagnostic and therapeutic procedure used to identify and treat the source of nerve pain in the spine. By precisely targeting an individual nerve root with a small injection of anesthetic and steroid medication, our specialists can confirm whether that nerve is the cause of your symptoms while also reducing pain and inflammation.

Why Are They Performed?

SNRBs are commonly recommended for patients who experience:

 

  • Chronic neck or lower back pain

  • Pain radiating into the arms or legs (radiculopathy)

  • Numbness, tingling, or weakness related to nerve irritation

  • Conditions such as herniated discs, spinal stenosis, or degenerative disc disease

These injections are especially useful when imaging alone does not provide clear answers. By temporarily numbing a specific nerve, physicians can identify the exact source of discomfort and tailor treatment more effectively.

How the Procedure Works

At Covenant Spine and Neurology, selective nerve root blocks are performed using advanced image guidance (fluoroscopy or ultrasound) to ensure accuracy and safety. The procedure typically involves:

 

  1. Preparation: The patient is positioned comfortably, and the skin is sterilized.

  2. Local Anesthetic: A numbing agent is applied to minimize discomfort.

  3. Precise Needle Placement: Using imaging, the physician carefully positions a needle near the targeted nerve root.

  4. Injection: A small amount of anesthetic (for immediate relief) and corticosteroid (to reduce inflammation) is delivered.

The process usually takes less than 30 minutes, and patients can go home the same day.

Benefits of Selective Nerve Root Blocks

Patients often experience significant advantages from SNRBs, including:

 

  • Accurate diagnosis of the exact nerve responsible for pain

  • Reduced inflammation and relief from radiating arm or leg pain

  • Improved mobility and function for daily activities

  • Enhanced participation in physical therapy and rehabilitation programs

  • Avoidance or delay of surgery when conservative treatments are effective

What to Expect After the Procedure

Some patients feel immediate relief from the anesthetic, while others notice gradual improvement as the steroid medication takes effect over several days. Relief may last weeks or months depending on the underlying condition. Your physician will review results and discuss whether additional injections or other treatments may be beneficial.
