Longer-Lasting Treatment for Lumbar Facet Joint Pain and Back Arthritis
Chronic lower back pain can originate from several different structures. For some patients, the source is the small joints along the back of the lumbar spine known as the facet joints.
When diagnostic lumbar medial branch blocks confirm that the facet joints are contributing to pain, lumbar radiofrequency ablation (RFA) may be considered to provide longer-lasting relief.
Lumbar radiofrequency ablation is a minimally invasive procedure that uses controlled radiofrequency energy to disrupt selected medial branch nerves responsible for transmitting pain signals from the lumbar facet joints.
At TOPS Institute, we provide image-guided lumbar radiofrequency ablation in Los Angeles and Beverly Hills as part of a diagnosis-driven approach to chronic low back pain. By confirming the pain source before treatment, we can determine whether lumbar RFA is appropriate for each patient.

What Is Lumbar Radiofrequency Ablation?
Lumbar radiofrequency ablation is a minimally invasive procedure that uses controlled radiofrequency energy to reduce pain signals transmitted by selected medial branch nerves associated with the facet joints of the lower spine.
The lumbar facet joints are paired joints located along the back of the spine. They help provide stability while allowing controlled movement.
Small nerves known as medial branch nerves transmit pain signals from these joints.
During lumbar RFA, a specialized needle is positioned near the appropriate medial branch nerve. Controlled radiofrequency energy creates a targeted thermal lesion that reduces the nerve’s ability to transmit pain.
The procedure is also sometimes referred to as:
- Lumbar radiofrequency neurotomy
- Lumbar facet radiofrequency ablation
- Medial branch radiofrequency ablation
- Radiofrequency denervation
Lumbar RFA does not remove the facet joint or reverse arthritis. Its purpose is to reduce pain transmission from a confirmed facet pain source.
What Does Lumbar Radiofrequency Ablation Treat?
Lumbar RFA is primarily used for chronic facet-mediated lower back pain.
It may be considered for selected patients with:
- Lumbar facet joint pain
- Lumbar spondylosis
- Lumbar facet arthritis
- Chronic axial low back pain
- Degenerative lumbar spine changes
- Persistent mechanical back pain
Patients may experience symptoms such as:
- Aching lower back pain
- Back stiffness
- Pain with standing
- Pain with lumbar extension
- Pain with twisting or rotation
- Referred pain into the buttocks
- Pain extending toward the hips or upper thighs
- Reduced ability to perform normal activities
Lumbar RFA is not a universal treatment for lower back pain. Determining whether the facet joints are responsible is an important part of patient selection.
Lumbar Radiofrequency Ablation for Back Arthritis
Lumbar spondylosis, commonly referred to as back arthritis, involves degenerative changes within the lumbar spine.
These changes may affect the:
- Facet joints
- Intervertebral discs
- Vertebrae
- Surrounding ligaments
When degeneration affects the facet joints and those joints become painful, patients may develop persistent axial lower back pain.
Lumbar radiofrequency ablation does not repair arthritis, regenerate cartilage, or reverse structural degeneration.
Instead, it targets the medial branch nerves responsible for carrying pain signals from the affected facet joints.
For appropriately selected patients, reducing these pain signals may improve comfort, mobility, and function.

How Do Lumbar Medial Branch Blocks Lead to Radiofrequency Ablation?
Diagnostic lumbar medial branch blocks are an important part of determining whether a patient may benefit from lumbar RFA.
A typical pathway is:
Suspected Lumbar Facet Joint Pain
↓
Diagnostic Lumbar Medial Branch Block
↓
Meaningful Temporary Relief of Typical Pain
↓
Evidence Supporting Facet-Mediated Pain
↓
Lumbar Radiofrequency Ablation for an Appropriate Candidate
During a medial branch block, local anesthetic is placed near the nerves carrying pain signals from the suspected facet joints.
If temporarily numbing these nerves produces the expected improvement in the patient’s typical pain, the response provides evidence that the corresponding facet joints may be significant pain generators.
Specific criteria for proceeding to RFA can vary according to clinical guidelines and insurance requirements.

How Does Lumbar Radiofrequency Ablation Work?
Radiofrequency ablation uses electrical energy to generate controlled heat at the tip of a specialized needle.
The physician positions the needle near a selected medial branch nerve.
Radiofrequency energy is then delivered to create a controlled lesion in the targeted nerve.
This interrupts the nerve’s ability to transmit pain signals from the facet joint toward the central nervous system.
Importantly, RFA does not permanently remove the nerve.
Medial branch nerves can regenerate over time, which is one reason pain may eventually return after a period of improvement.
How Is Lumbar Radiofrequency Ablation Performed?
Lumbar RFA is generally performed as an outpatient procedure using image guidance.
The procedure typically involves:
- The patient is positioned to allow access to the lumbar spine.
- The treatment area is cleaned and prepared.
- Local anesthetic may be used to numb the skin and surrounding tissues.
- Using image guidance, specialized needles are carefully positioned near the targeted medial branch nerves.
- Testing may be performed to help confirm appropriate positioning.
- Radiofrequency energy is delivered through the needle to create a controlled lesion at the targeted nerve.
- Additional nerves may be treated when clinically appropriate.
- The needles are removed, and the patient is monitored after the procedure.
The specific levels treated depend on which facet joints have been identified as contributing to the patient’s pain.
Why Is Image Guidance Used for Lumbar RFA?
The medial branch nerves are small and follow predictable anatomical pathways near the vertebrae.
Image guidance allows the physician to accurately identify relevant spinal anatomy and position the radiofrequency needles near the intended nerve targets.
Because the goal is to treat selected medial branch nerves rather than surrounding tissues, accurate needle positioning is an important part of the procedure.
Lumbar Radiofrequency Ablation vs. Medial Branch Block
A lumbar medial branch block and lumbar radiofrequency ablation target the same general nerves but serve different purposes.
Lumbar Medial Branch Block
A medial branch block uses local anesthetic to temporarily numb the nerve.
Its primary purpose is diagnostic—to determine whether the corresponding facet joints are contributing to the patient’s pain.
Lumbar Radiofrequency Ablation
RFA uses controlled radiofrequency energy to create a lesion in the targeted nerve and provide a longer-lasting interruption of pain transmission.
In many patients, the medial branch block comes first and RFA is considered only if the diagnostic response supports facet-mediated pain.

Lumbar Radiofrequency Ablation vs. Facet Joint Injection
These procedures are also different.
Lumbar Facet Joint Injection
A facet joint injection places medication directly into the joint.
Lumbar Radiofrequency Ablation
RFA targets the medial branch nerves that carry pain signals from the joint.
Facet joint injections may be considered in selected circumstances, while medial branch blocks and RFA form a separate diagnostic and therapeutic pathway for confirmed facet-mediated pain.

Lumbar Radiofrequency Ablation vs. Epidural Steroid Injection
One of the most important distinctions for patients is the difference between facet-mediated back pain and sciatica.
Lumbar Radiofrequency Ablation
Lumbar RFA targets medial branch nerves associated with the facet joints.
It is primarily used for chronic axial low back pain arising from these joints.
Lumbar Epidural Steroid Injection
An epidural steroid injection delivers anti-inflammatory medication into the epidural space around spinal nerve roots.
It may be used for conditions such as lumbar radiculopathy and sciatica.
If a patient has shooting or burning pain traveling down the leg because of an irritated spinal nerve, RFA of the lumbar medial branches generally does not address that nerve-root pain.

Does Lumbar Radiofrequency Ablation Help Sciatica?
Lumbar medial branch radiofrequency ablation is not generally used to treat classic sciatica.
Sciatica commonly results from irritation or compression of a lumbar spinal nerve root.
Possible causes include:
- Lumbar disc herniation
- Foraminal stenosis
- Lumbar spinal stenosis
- Other conditions affecting a spinal nerve
Lumbar facet RFA instead targets the medial branch nerves associated with facet-mediated back pain.
Patients with sciatica may require a different treatment approach, such as an epidural steroid injection, depending on the underlying diagnosis.
Learn More About Lumbar Radiculopathy (Sciatica)
Who Is a Candidate for Lumbar Radiofrequency Ablation?
Lumbar RFA may be considered for patients with chronic lower back pain when diagnostic evaluation supports a facet joint source.
Potential candidates may include patients who:
- Have chronic axial lower back pain
- Have lumbar facet-mediated pain
- Have lumbar spondylosis or facet arthritis
- Experience pain with back extension or rotation
- Have persistent pain despite appropriate conservative treatment
- Experience meaningful temporary relief after diagnostic medial branch blocks
- Are medically appropriate for the procedure
The presence of facet arthritis on imaging alone does not establish that a patient should undergo RFA.
The patient’s symptoms, examination, and response to diagnostic blocks are important parts of treatment selection.
How Long Does Lumbar Radiofrequency Ablation Last?
The duration of pain relief varies from patient to patient.
For appropriately selected patients, improvement may last for several months or longer.
Eventually, the targeted medial branch nerves can regenerate and regain their ability to transmit pain signals.
The underlying arthritis or degeneration may also remain present.
For these reasons, lumbar radiofrequency ablation is not considered a permanent cure.
Can Lumbar Radiofrequency Ablation Be Repeated?
Yes, repeat lumbar RFA may be considered for selected patients.
If a patient experiences meaningful relief following the initial procedure and the same facet-mediated pain later returns, reevaluation can help determine whether repeating RFA is appropriate.
Factors considered may include:
- Degree of previous pain relief
- Duration of improvement
- Current symptoms
- Functional improvement
- Changes in medical status
- Clinical guidelines
Repeat RFA should be individualized rather than automatically scheduled.
How Quickly Does Lumbar Radiofrequency Ablation Work?
Pain relief is not always immediate.
Some patients notice improvement relatively soon, while others may require several days or longer before the full benefit becomes apparent.
Temporary soreness or increased discomfort can occur after the procedure.
This does not necessarily indicate that the procedure was unsuccessful.
Patients should follow their physician’s post-procedure instructions and discuss any unexpected or concerning symptoms.
What Is Recovery Like After Lumbar RFA?
Lumbar radiofrequency ablation is generally performed on an outpatient basis.
Patients may experience:
- Localized soreness
- Tenderness
- Temporary muscle discomfort
- Temporary increase in pain
Specific recommendations regarding driving, exercise, work, and other activities vary depending on the patient and procedure.
Once discomfort improves, patients may be able to participate more comfortably in:
- Physical therapy
- Core strengthening
- Mobility exercises
- Appropriate exercise
- Other rehabilitation strategies
Reducing pain can be particularly valuable when it allows a patient to become more active and improve function.
Are Lumbar Radiofrequency Ablations Safe?
Lumbar RFA is a minimally invasive procedure, but all medical procedures have potential risks.
Potential risks and side effects may include:
- Temporary procedure-site soreness
- Temporary increase in pain
- Bleeding
- Infection
- Numbness
- Neuritis or nerve irritation
- Temporary muscle discomfort
- Nerve injury
- Other uncommon complications
Patients taking blood-thinning medications or those with certain medical conditions may require additional procedural planning.
Potential benefits, risks, and alternatives should be reviewed before treatment.
Does Lumbar RFA Damage the Spine?
Lumbar radiofrequency ablation does not remove spinal bones, discs, or facet joints.
The procedure targets selected medial branch nerves responsible for carrying pain signals from the facet joints.
The goal is to reduce pain transmission while preserving the underlying spinal anatomy.
However, as with any interventional procedure, appropriate patient selection and precise technique are important.
When Is Lumbar RFA Not the Right Treatment?
Lumbar RFA is specifically intended for appropriately selected patients with facet-mediated pain.
It may not be the appropriate treatment when the primary source of symptoms is:
- Lumbar radiculopathy
- Sciatica
- Lumbar disc herniation causing nerve-root symptoms
- Sacroiliac joint dysfunction
- Significant spinal stenosis producing nerve symptoms
- Other non-facet sources of back pain
For example, a patient with sacroiliac joint pain may require an SI joint-directed treatment, while a patient with lumbar radiculopathy may require a nerve-root-directed treatment.

What is lumbar radiofrequency ablation?
Lumbar radiofrequency ablation is a minimally invasive procedure that uses controlled radiofrequency energy to reduce pain signals carried by selected medial branch nerves associated with the lumbar facet joints.
What does lumbar RFA treat?
Lumbar RFA is primarily used for confirmed facet-mediated lower back pain, including pain associated with lumbar spondylosis and facet arthritis.
Is lumbar RFA good for back arthritis?
It may help selected patients when arthritis or degeneration of the lumbar facet joints is confirmed as a significant source of pain. RFA does not reverse the arthritis itself.
Do I need a medial branch block before lumbar RFA?
Diagnostic lumbar medial branch blocks are commonly used before RFA to determine whether the facet joints are contributing to the patient’s pain.
Learn More About Lumbar Medial Branch Blocks
How long does lumbar radiofrequency ablation last?
The duration varies. Some patients experience meaningful pain reduction for several months or longer. Pain may eventually return as the targeted nerves regenerate.
Can lumbar radiofrequency ablation be repeated?
Yes. If a patient experienced meaningful benefit and the same facet-mediated pain later returns, repeat RFA may be considered after reevaluation.
Does lumbar RFA help sciatica?
Lumbar medial branch RFA is generally not used to treat classic sciatica because it targets nerves associated with the facet joints rather than the spinal nerve roots responsible for radicular leg pain.
Learn More About Lumbar Radiculopathy (Sciatica)
Is lumbar RFA the same as an epidural steroid injection?
No. RFA targets medial branch nerves carrying pain signals from the facet joints. Epidural steroid injections deliver medication around spinal nerve roots and are commonly used for radicular pain.
Is lumbar RFA the same as a nerve block?
No. A medial branch block temporarily numbs selected nerves for diagnostic purposes. RFA uses controlled radiofrequency energy to produce a longer-lasting interruption of pain transmission.
Does lumbar radiofrequency ablation permanently destroy the nerve?
No. The targeted medial branch nerves can regenerate over time, which is why pain may eventually return.
Is lumbar radiofrequency ablation surgery?
No. Lumbar RFA is a minimally invasive interventional procedure and does not involve removing spinal tissue or making a traditional surgical incision.
