Radiofrequency Nerve Ablation

What is Radiofrequency Ablation?

Radiofrequency nerve ablation (also known as radiofrequency lesioning, or neurotomy) is an emerging therapy in pain medicine that uses a specialized device to disrupt nerve conduction on a semi-permanent basis.

Radiofrequency nerve ablation is a minimally invasive procedure used to alleviate chronic pain caused by certain conditions such as arthritis, facet joint dysfunction, or nerve irritation. It involves using heat generated by radiofrequency waves to disrupt the function of specific nerves that transmit pain signals.

With radiofrequency treatment, the nerves are usually blocked for 6-9 months, but relief can be as short as 3 months or as long as 18 months for some patients. This nerve ablation pain relief technique can be used successfully for those with back pain, neck pain, muscle pain, or other discomforts. A probe is inserted through a needle and controlled delivery of heat is placed along a painful nerve. Radiofrequency uses heat to disrupt the nerves' conductivity.

Radiofrequency Nerve Ablation Benefits

  • Pain relief for up to 18 months
  • Minimally invasive
  • Short recovery
  • High success rates
  • Local anesthesia
  • Minimal or no blood loss
  • Same-day, outpatient procedure

Who is a Candidate for a Radiofrequency Nerve Ablation?

Radiofrequency nerve ablation is typically considered as a treatment option for individuals who experience chronic pain originating from specific nerves or areas of the body. The procedure is commonly used to address pain caused by conditions such as arthritis, facet joint dysfunction, or nerve irritation. While the suitability for a nerve ablation procedure can vary based on individual circumstances, here are some factors that may make a person a potential candidate for radiofrequency nerve ablation:

  • Spinal arthritis
  • Spinal stenosis
  • Facet arthritis
  • Whiplash
  • Sprains & Strains

Before considering RFA, it's common for healthcare providers to perform diagnostic nerve blocks. These blocks involve temporarily numbing the suspected nerves using a local anesthetic. If a diagnostic nerve block provides significant pain relief, it suggests that the targeted nerves are indeed the source of the pain, making the person a potential candidate for RFA.

Imaging studies such as X-rays, magnetic resonance imaging (MRI), or computed tomography (CT) scans may reveal abnormalities or conditions that can be effectively treated with back ablation. For example, if facet joint arthritis or a nerve impingement is identified as the cause of pain, spinal ablation may be considered a viable option.

Candidates for RFA should have tried conservative treatments without achieving satisfactory pain relief. This could include options like physical therapy, medications (such as anti-inflammatories or analgesics), rest, or other non-invasive or minimally invasive interventions. Ablation for back pain is generally considered when these conservative measures have not provided adequate long-term pain control.

A thorough evaluation of a person's overall health and medical history is crucial when considering RFA. Factors such as allergies, bleeding disorders, infections, or pregnancy can affect the suitability of the procedure. It's essential to discuss any underlying medical conditions or concerns with your healthcare provider to ensure RFA is safe and appropriate for you.

Radiofrequency Nerve Ablation Risks

Nerve ablation of facet joints is performed in an operative setting using mild sedation and local anesthetics. Fluoroscopic x-ray guidance allows the physician to accurately position the radiofrequency ablation probe adjacent to the medial branch nerves to be treated. The nerve is then heated to 80 degrees C using a radiofrequency generator. Radiofrequency ablation treatment is a safe and well-tolerated method selected to treat chronic pain caused by a variety of conditions. If your pain responds well to an initial treatment, a follow-up treatment may be helpful.

Radiofrequency Nerve Ablation Recovery

After undergoing radiofrequency nerve ablation, proper recovery is crucial to maximizing the benefits of the procedure.

After the radiofrequency nerve ablation, you will likely be monitored in a recovery area for a short period. This allows healthcare professionals to observe your initial response to the procedure and ensure there are no immediate complications. You may experience some discomfort or soreness at the site of the procedure, but this is typically mild and temporary.

Following the procedure, it's important to give your body time to heal. Your healthcare provider will provide specific instructions regarding activity limitations and restrictions. Generally, you may be advised to avoid strenuous activities, heavy lifting, or excessive bending and twisting for a certain period. Engaging in light activities and gentle movements, such as walking, is usually encouraged to prevent stiffness and promote circulation.

While radiofrequency nerve ablation is intended to reduce pain, it's common to experience some temporary discomfort or soreness in the treated area during the recovery phase. Your healthcare provider may prescribe pain medications or recommend over-the-counter pain relievers to manage any discomfort. It's essential to follow the prescribed pain management regimen and report any severe or prolonged pain to your healthcare provider.

The full benefits of radiofrequency nerve ablation may not be immediately apparent after the procedure. It can take several weeks for the treated nerves to fully lose their function and for pain relief to be realized. During this time, you may notice a gradual improvement in your symptoms as the nerves heal and inflammation subsides. It's important to be patient and realistic in your expectations, as individual responses to the procedure can vary.

Your healthcare provider will schedule follow-up appointments to monitor your progress and assess the effectiveness of the radiofrequency nerve ablation. These appointments allow them to evaluate your pain levels, address any concerns or complications, and make any necessary adjustments to your ongoing pain management plan.

In some cases, your healthcare provider may recommend a rehabilitation program or physical therapy to complement the effects of radiofrequency nerve ablation. These therapies can help improve flexibility, strength, and overall function while promoting a faster and more complete recovery. Your healthcare provider will guide you on when it is appropriate to start these activities and what exercises or treatments are suitable for your condition.

It's important to note that individual recovery experiences can vary, and it's crucial to follow your healthcare provider's specific instructions regarding post-procedure care and activity restrictions. If you have any questions, concerns, or unexpected symptoms during your recovery, it's important to reach out to your healthcare provider for guidance and clarification. By actively participating in your recovery and following the recommended guidelines, you can optimize the outcomes of radiofrequency nerve ablation and achieve long-lasting pain relief.
