At Vertex Pain Physicians, we are dedicated to providing compassionate care for patients dealing with chronic pain. One of our specialized treatments, Radiofrequency Ablation (RFA) of Medial Branch Nerves, is a minimally invasive procedure that offers long-lasting pain relief by targeting the source of your discomfort. This innovative treatment can help you regain comfort, and mobility, and improve your quality of life.
What Is Radiofrequency Ablation (RFA) of Medial Branch Nerves?
Radiofrequency Ablation (RFA) is a minimally invasive procedure that treats chronic pain caused by the facet joints of the spine by disrupting nerve function. This technique uses heat generated by radiofrequency energy to target specific nerves responsible for transmitting pain signals to the brain. By applying heat to these nerves and interrupting their ability to transmit pain signals to the brain, this therapy provides significant and often long-term relief.
How Does RFA Work?
During Radiofrequency Ablation (RFA), a specialized needle is guided to the targeted nerve using X-Ray or fluoroscopic imaging to ensure precise placement. After placement of the RFA needles are complete, sensory and motor testing is initiated for confirmation of the patient’s pain symptoms. Once the correct nerves are identified, radiofrequency energy is delivered through the needle for one to two minutes. The heat from the energy creates a small lesion on the nerve, disrupting its ability to send pain signals to the brain, and resulting in improved pain relief. While the nerve is not permanently destroyed, it takes time to regenerate, allowing patients to experience relief for an extended period. Most patients will have pain relief that lasts between six months to two years before requiring a repeat ablation procedure.
What Conditions Can Be Treated with RFA?
RFA can be used to treat various conditions associated with chronic pain, including:
Facet Joint Pain
Chronic neck, mid-back, or lower back pain due to arthritis or degeneration of the facet joints in the spine.
Sacroiliac Joint Pain
Pain originating from the sacroiliac joints, which connect the spine to the pelvis.
Arthritis-related Pain
Pain in the spine or peripheral joints, particularly when conservative treatments have been ineffective.
Spinal Osteoarthritis (Spondylosis)
Degenerative changes in the spine leading to chronic pain.
Chronic Back Pain
Persistent lower back pain from conditions like degenerative disc disease.
Whiplash Injuries
Post-traumatic pain in the cervical spine from accidents or injuries.
Neuropathic Pain
Pain caused by damaged or irritated nerves in specific, localized areas.
Post-Surgical Pain Syndrome
Persistent pain after spinal or orthopedic surgeries.
Coccydynia
Tailbone pain that has not responded to other treatments.
RFA is often recommended when other non-invasive treatments, such as medications or physical therapy, have failed to provide relief.
Benefits of RFA for Medial Branch Nerves
Here are some key benefits of Radiofrequency Ablation:
Reduced Dependence on Medications
By directly targeting the source of pain, RFA can reduce the need for pain-relief medications.
Long-Lasting Pain Relief
RFA provides relief that can last anywhere from 6 months to 2 years, depending on individual factors.
Quick Recovery
Most patients can return to normal activities within a few days.
Minimally Invasive
This procedure is performed on an outpatient basis, meaning no need for hospitalization.
Procedure Details
1
Pre-Procedure Preparation
Before the procedure, your doctor will review your current medications. You may need to stop taking certain medications, such as blood thinners, temporarily for safety. Additionally, you may be instructed to avoid eating or drinking for a few hours before the procedure.
2
On the Day of the Procedure
The RFA procedure typically lasts 30 to 60 minutes. Here’s how it works:
- Patient Positioning: You will lie down on an exam table, and the area to be treated. Your back will be cleaned with a disinfectant.
- Localization: Fluoroscopy (X-ray guidance) is used to identify the joints that will be treated with local anesthesia.
- Anesthesia: Local anesthesia is administered at the insertion site to reduce discomfort when placing the needle.
- Needle Placement: A specialized RFA needle is advanced toward the medial or lateral branch nerves near the joint.
- Sensory and Motor Testing: Electrical stimulation confirms accurate nerve targeting while minimizing the risk of affecting motor nerves. This confirms the nerve responsible for transmitting your pain signals. You may feel a slight tingling or pressure during this step.
- Lesion Formation: Once the correct nerve is identified, the doctor will deliver radiofrequency energy through the needle. The heat generated creates a lesion on the nerve, interrupting its ability to transmit pain signals. This takes about 60–120 seconds.
- Post-Procedure Monitoring: After the procedure, the needle is removed, and a small bandage is applied to the injection site. We observe you for 5-10 minutes to make sure you are recovering well before being discharged home.

Post-Procedure Care
After your procedure, you will rest briefly before going home. Most patients can walk out of the clinic on their own. It is normal to experience mild soreness or tenderness at the injection site for a few days. Applying ice packs and using over-the-counter pain relievers (as advised by your doctor) can help manage discomfort.
You should avoid strenuous activities for 24 to 48 hours but can return to light daily activities as you feel comfortable. Follow-up visits may be scheduled to monitor your progress and assess the effectiveness of the procedure.
Most patients begin to notice significant pain relief within 1 to 3 weeks after the procedure, as the treated nerve stops transmitting pain signals.

Risks and Side Effects
Although RFA is generally safe, potential risks and side effects may include:
- Temporary numbness or weakness
- Mild swelling or bruising at the injection site
- Rare complications such as infection, allergic reaction, or nerve damage
Your doctor will discuss these risks with you and ensure that you are a good candidate for the procedure.

Frequently Asked Questions
Is the RFA procedure painful?
Most patients experience only mild discomfort during the procedure due to the local anesthetic used to numb the area.
Can nerves grow back after ablation?
Yes, nerves can regenerate over time, which may result in the return of pain. However, the procedure can be repeated if necessary.
How long does it take for a nerve to stop transmitting pain signals after ablation?
The nerve immediately stops transmitting pain signals, though the full effect may take a few days to weeks.
How long does it take to see results?
Pain relief typically begins within a few weeks, as the treated nerve stops transmitting pain signals.
What is the success rate of medial branch ablation?
The success rate varies, with 70-80% of patients experiencing significant pain relief that can last 6 months to 2 years.
How long does it take to feel better after radiofrequency ablation?
Most patients begin to experience significant pain relief within 1 to 3 weeks after the procedure.
