Nerve Root Injections & Radiofrequency Ablation
Book Your ConsultationImage-guided nerve root injection and radiofrequency ablation is used to treat pain resulting from inflammation or direct pressure on a specific nerve root, whether caused by a herniated disc or spinal canal narrowing.
This technique is distinguished by its high precision, being performed entirely under interventional radiology guidance to ensure the treatment reaches the targeted spot with extreme accuracy and high safety compared to general, unguided injections.
This procedure is a fundamental part of the interventional pain management system, used alone in some cases or as a complementary step within a broader treatment plan for various spinal conditions.
Precise coordination between the treating physician and the interventional radiology team is an essential element in this procedure’s success, ensuring the correct nerve root is identified and the most suitable needle path chosen with minimal discomfort for the patient. Each case’s results are carefully reviewed after the procedure to determine whether the treatment plan needs adjusting or a complementary procedure added at a later stage.
Common Causes
- Inflammation of spinal nerve roots from direct mechanical pressure on them
- Spinal canal narrowing that reduces the space available for nerves to pass through
- A chronic herniated disc pressing on a specific nerve root
- Inflammatory changes accompanying vertebral wear with age
- Residual inflammation after previous spinal injuries or surgeries
- Accumulated repeated minor injuries at a certain vertebral level over time
Symptoms
- Localized pain precisely following the path of the affected nerve
- Clear numbness or weakness in the limb associated with the affected nerve
- Increased pain with standing or walking for long periods
- Relative improvement in pain when sitting or bending forward in some cases
- Difficulty precisely identifying the source of pain without a specialized assessment
- Pain intensity varying day to day depending on physical activity level
- Accompanying, noticeable muscle tension in the area directly surrounding the affected nerve root

How Is It Diagnosed?
Diagnosis relies on precisely identifying the affected nerve root through a neurological exam and matching the distribution of pain with the nerve’s anatomically known path.
An MRI is used to clarify the cause of pressure on the root, whether a herniation, narrowing, or inflammatory change, which precisely determines the targeted nerve root during the procedure.
Treatment Steps
After precisely identifying the targeted nerve root, the procedure is performed entirely under direct imaging guidance to ensure the needle reaches exactly the correct spot.
Local anti-inflammatory injections are used around the nerve root to quickly and effectively reduce swelling and pressure on it during the same session.
When a longer-lasting effect is needed, radiofrequency ablation is used to reduce the sensitivity of the affected nerve root for a period extending several months.
All of this is performed under local anesthesia only, with the patient going home the same day without needing a hospital stay.
A follow-up is scheduled afterward to assess how well the nerve responded to treatment and determine the need for any additional session if necessary.
Is This Treatment Right for You?
This procedure suits patients where a clear nerve root has been identified as the main source of pain through exam and imaging, and who are looking for precise, targeted treatment rather than general solutions.
It also benefits those who’ve had limited response to general medication and need a more precise intervention that directly targets the source of pain.
The doctor determines suitability after a comprehensive review of imaging and neurological exam results, to ensure the correct nerve root is actually targeted.
Aftercare Tips
- Avoid strenuous physical effort during the first few days immediately after the procedure
- Follow up with the doctor to assess symptom improvement over the following weeks
- Adhere to any complementary physical therapy program recommended by the treating doctor
- Report any new or unusual symptoms immediately after the procedure
- Avoid driving yourself immediately after the session and bring a companion for the day of the procedure

Frequently Asked Questions
What’s the difference between this procedure and regular injections?
It’s distinguished by its high precision in targeting a specific nerve root under direct imaging guidance, unlike general, unguided injections.
Does the procedure need general anesthesia?
No, it’s performed entirely under local anesthesia only with careful medical supervision throughout the procedure.
When does the procedure’s result appear?
Some patients may feel improvement within a few days, while others need two weeks to notice the full difference.
Is the procedure completely safe?
It’s a relatively safe procedure when performed with precise imaging guidance by a physician specialized in interventional pain management.
Could a patient need more than one nerve root in the same session?
In some cases, yes, if the assessment shows more than one nerve root affected by the same underlying problem.
Can injections be given for more than one nerve root in separate sessions?
Yes, separate sessions can be planned for each nerve root based on the doctor’s assessment and how well each area responds to treatment.
