TREATMENT OVERVIEW

Selective Nerve Root Block (SNRB)

A Selective Nerve Root Block is a precision injection technique that serves dual purposes: diagnosing which specific nerve root is causing your pain and providing therapeutic relief. By delivering medication directly to an individual nerve root where it exits the spine, we can pinpoint the source of radiating pain and provide targeted treatment for conditions affecting the nerve roots.

Quick Facts

  • • Procedure Duration: 20-30 minutes
  • • Recovery Time: 30 minutes observation, then home
  • • Pain Relief Onset: Within hours to days
  • • Success Rate: 85-90% for appropriate candidates

PROCEDURE DETAILS

What is the Procedure?

A Selective Nerve Root Block involves injecting a small amount of anesthetic and anti-inflammatory medication around a specific nerve root as it exits the spinal column. This targeted approach allows us to identify exactly which nerve is responsible for your pain while simultaneously providing therapeutic relief.

The procedure is performed using fluoroscopy (live X-ray) or CT guidance to ensure precise needle placement. After numbing the skin with local anesthetic, a thin needle is carefully guided to the targeted nerve root. Contrast dye may be injected first to confirm proper needle position and medication spread pattern.

Once positioned correctly, a combination of local anesthetic and corticosteroid is injected around the nerve root. The anesthetic provides immediate diagnostic information and pain relief, while the steroid reduces inflammation for longer-lasting therapeutic benefit, often lasting weeks to months.

TREATMENT ADVANTAGES

What are the Benefits?

Selective Nerve Root Blocks offer both diagnostic clarity and therapeutic relief, making them invaluable for managing nerve-related pain conditions.

Precise Diagnosis

Identifies the exact nerve root causing your pain, essential for planning effective treatment strategies including potential surgery.

Targeted Treatment

Delivers medication directly to the affected nerve root, maximizing therapeutic effect while minimizing systemic side effects.

Extended Relief

While diagnostic effects are temporary, the anti-inflammatory medication can provide pain relief lasting weeks to several months.

Avoids Surgery

May help patients avoid or delay surgery by providing significant pain relief and improved function through conservative treatment.

Improved Mobility

Reduces nerve pain and inflammation, allowing better participation in physical therapy and daily activities.

Repeatable Procedure

Can be safely repeated if needed, providing ongoing management option for chronic nerve pain conditions.

IMPORTANT INFORMATION

What are the Risks and Side Effects?

Selective Nerve Root Blocks are generally very safe when performed by experienced practitioners. However, as with any injection procedure, there are potential risks to consider.

Common Side Effects

  • Temporary increase in pain for 24-48 hours
  • Numbness or weakness in the affected limb
  • Soreness at the injection site
  • Temporary headache or dizziness

Rare Complications

  • Nerve damage or irritation
  • Infection at the injection site
  • Allergic reaction to medications
  • Bleeding or hematoma formation

Important: The use of image guidance and sterile technique significantly minimizes these risks. Dr. Fura will review your medical history and current medications to ensure this procedure is safe for you.

PREPARATION GUIDE

How to Prepare for the Procedure?

Proper preparation helps ensure a safe, comfortable procedure and optimal results. Follow these guidelines carefully.

1

Medical Review

Inform us of all medications, allergies, and medical conditions. Bring recent MRI or CT scan results to your appointment.

2

Medication Instructions

Stop blood thinners 5-7 days before if instructed. Continue other medications unless specifically told to stop.

3

Day of Procedure

Eat a light meal 2 hours before. Arrange for someone to drive you home. Wear comfortable, loose clothing.

4

What to Bring

Insurance cards, photo ID, list of current medications, and any relevant imaging studies or reports.

RECOVERY GUIDE

What is the Post-Procedure Care?

Recovery from a Selective Nerve Root Block is typically quick and straightforward. Following these guidelines will help ensure the best possible outcome.

Immediate Post-Procedure

You'll be monitored for 20-30 minutes after the injection. Temporary numbness or weakness in the affected limb is normal and expected. Keep a pain diary to track your response to the injection.

First 24 Hours

Rest and avoid strenuous activities. Apply ice to the injection site if sore. Do not drive or operate machinery if experiencing numbness or weakness. Take pain medications as prescribed if needed.

Days 2-7

Gradually resume normal activities as tolerated. The steroid medication begins working within 2-3 days, with maximum effect typically seen at 7-10 days. Continue documenting your pain levels and functional improvements.

Follow-up Visit

Your follow-up appointment typically occurs 2-4 weeks after the procedure. We'll review your pain diary, assess the effectiveness of the injection, and determine next steps in your treatment plan.

When to Contact Your Doctor

  • Severe or worsening pain
  • Signs of infection (fever, redness, drainage)
  • Persistent numbness or weakness beyond 24 hours
  • Severe headache or neck stiffness
  • Difficulty with bladder or bowel control
  • Signs of allergic reaction

CONDITIONS TREATED

When is SNRB Recommended?

Selective Nerve Root Blocks are particularly effective for specific conditions affecting individual nerve roots.

Herniated Disc

When disc material compresses a specific nerve root causing radiating pain down the arm or leg.

Spinal Stenosis

Narrowing of the spinal canal causing nerve compression and radiating symptoms.

Radiculopathy

Nerve root irritation causing pain, numbness, or weakness along the nerve pathway.

Failed Back Surgery

Persistent nerve pain following spinal surgery requiring targeted diagnostic evaluation.

Spondylolisthesis

Slippage of one vertebra over another causing nerve root compression.

Pre-Surgical Planning

To identify the specific nerve root requiring surgical intervention.

Diagnostic Value

The diagnostic information from SNRB is particularly valuable when:

  • MRI shows multiple levels of nerve compression
  • Symptoms don't match imaging findings
  • Planning minimally invasive or surgical treatment
  • Confirming the pain source before more invasive procedures

Find the Source of Your Nerve Pain

If you're experiencing radiating pain, numbness, or weakness, a Selective Nerve Root Block can provide both answers and relief. Schedule a consultation with Dr. Fura to determine if this targeted treatment is right for you.
