Targeted Treatment for Facet-Mediated Low Back Pain and Lumbar Arthritis
Persistent aching or stiffness in the lower back does not always originate from a disc or pinched nerve. For some patients, pain develops from the small joints along the back of the lumbar spine known as the facet joints.
These joints can become painful because of arthritis, degeneration, injury, or mechanical stress. When the lumbar facet joints are suspected of contributing to chronic low back pain, a lumbar facet joint injection may be considered as part of a targeted treatment plan.
At TOPS Institute, we provide image-guided lumbar facet joint injections in Los Angeles and Beverly Hills as part of a diagnosis-driven approach to chronic back pain. Our goal is to identify the structure responsible for a patient’s symptoms and select treatment accordingly.

What Are the Lumbar Facet Joints?
Lumbar facet joints are small paired joints located along the back of the lower spine that help provide stability and guide spinal movement.
Each vertebra connects with adjacent vertebrae through facet joints.
These joints allow controlled movement while helping prevent excessive motion.
The lumbar facet joints are involved when the lower back:
- Bends
- Extends
- Rotates
- Moves from side to side
Like other joints in the body, facet joints contain cartilage and are surrounded by a joint capsule.
Over time, the cartilage and other joint structures can undergo degenerative changes. The joints may also become irritated following injury or repetitive mechanical stress.
When a facet joint becomes painful, it can contribute to persistent lower back pain and referred pain into nearby areas.
What Is Lumbar Facet Joint Pain?
Lumbar facet joint pain is pain originating from one or more facet joints in the lower spine.
Symptoms may include:
- Aching low back pain
- Lower back stiffness
- Pain with standing
- Pain with spinal extension
- Pain with twisting or rotation
- Reduced lower back mobility
- Pain extending into the buttocks
- Pain extending toward the hips or upper thighs
- Tenderness around the lower back
Facet-mediated pain is typically different from classic lumbar radiculopathy or sciatica.
Sciatica frequently produces sharp, burning, or electric-like pain traveling farther down the leg along the distribution of an affected nerve.
Facet pain more commonly remains in the lower back or refers into the buttock, hip, or upper thigh.
However, symptoms can overlap, making an appropriate evaluation important.
What Causes Lumbar Facet Joint Pain?
Several conditions and mechanical factors may contribute to painful lumbar facet joints.
Potential causes include:
- Lumbar spondylosis
- Back arthritis
- Age-related degeneration
- Degenerative disc disease
- Previous lower back injury
- Repetitive mechanical stress
- Changes in spinal biomechanics
As the lumbar spine changes with age or degeneration, the forces placed on the facet joints may increase.
For example, loss of intervertebral disc height may alter how forces are distributed through the spine and increase stress on the facet joints.

What Is a Lumbar Facet Joint Injection?
A lumbar facet joint injection is a minimally invasive procedure in which medication is delivered directly into a facet joint in the lower spine.
Depending on the purpose of treatment and individual clinical circumstances, medication may include:
- Local anesthetic
- Corticosteroid medication
The procedure may be used to reduce inflammation and pain associated with a targeted joint.
Facet injections may also provide clinical information about whether a particular joint contributes to the patient’s symptoms.
However, when evaluating whether a patient may be a candidate for radiofrequency ablation, medial branch blocks are commonly used to test the small nerves that transmit pain signals from the facet joints.
How Is a Lumbar Facet Joint Injection Performed?
Lumbar facet injections are generally performed as outpatient procedures 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.
- Using image guidance, the physician carefully advances a needle toward the targeted facet joint.
- Contrast material may be used when appropriate to evaluate needle placement.
- Medication is delivered into the joint.
- The needle is removed, and the patient is monitored after the procedure.
Image guidance allows the physician to accurately identify and access the small facet joints rather than relying on surface anatomy alone.
What Conditions Can Lumbar Facet Joint Injections Treat?
Lumbar facet joint injections may be considered when one or more facet joints are suspected of contributing to persistent lower back pain.
Potential conditions or circumstances include:
- Lumbar facet-mediated pain
- Lumbar spondylosis
- Lumbar facet arthritis
- Degenerative low back pain
- Selected cases of persistent mechanical back pain
The presence of arthritis on an X-ray or MRI does not necessarily mean that a facet joint is causing pain.
Degenerative findings are common, including among people without significant symptoms.
Clinical evaluation is therefore important when determining whether facet-directed treatment is appropriate.
Lumbar Facet Joint Injections for Back Arthritis
Lumbar spondylosis, commonly referred to as back arthritis, describes degenerative changes involving structures within the lower spine.
These changes may affect the:
- Facet joints
- Intervertebral discs
- Vertebrae
- Surrounding ligaments
When the facet joints become painful as part of this degenerative process, facet-directed procedures may be considered.
A lumbar facet joint injection does not reverse arthritis or rebuild damaged cartilage.
Instead, treatment focuses on reducing pain and inflammation associated with the affected joint.

Lumbar Facet Pain vs. Sciatica
Distinguishing facet-mediated back pain from lumbar radiculopathy or sciatica is important because the conditions involve different anatomical structures.
Lumbar Facet Joint Pain
Facet pain commonly causes:
- Aching lower back pain
- Back stiffness
- Pain with extension or rotation
- Referred pain into the buttocks or upper thighs
Sciatica / Lumbar Radiculopathy
Lumbar radiculopathy commonly causes:
- Shooting leg pain
- Burning pain
- Electric-like sensations
- Numbness
- Tingling
- Pain traveling farther down the leg
Lumbar radiculopathy involves irritation or compression of a spinal nerve root, while facet-mediated pain originates from a spinal joint.
An epidural steroid injection may be considered for selected patients with radicular pain, while facet-directed procedures may be more appropriate when the facet joints are identified as the pain source.

Lumbar Facet Joint Injection vs. Lumbar Epidural Steroid Injection
Both are minimally invasive spinal injections, but they target different structures.
Lumbar Facet Joint Injection
A facet injection delivers medication into a facet joint and may be considered for facet-mediated lower back pain.
Lumbar Epidural Steroid Injection
An epidural injection delivers medication into the epidural space surrounding spinal nerves and is generally used for radicular symptoms caused by an irritated or inflamed nerve root.
Choosing between them depends on what is causing the patient’s pain.

Lumbar Facet Joint Injection vs. Lumbar Medial Branch Block
A facet joint injection and medial branch block are closely related procedures, but they target different structures.
A lumbar facet joint injection places medication directly into the facet joint.
A lumbar medial branch block places local anesthetic near the medial branch nerves that transmit pain signals from the facet joints.
Medial branch blocks are commonly used as diagnostic procedures when evaluating whether a patient with suspected facet-mediated pain may be a candidate for radiofrequency ablation.

How Do Medial Branch Blocks Lead to Radiofrequency Ablation?
For selected patients with chronic facet-mediated back pain, the treatment pathway may include:
Suspected Lumbar Facet Pain
↓
Diagnostic Lumbar Medial Branch Block
↓
Evaluate Temporary Pain Relief
↓
Lumbar Radiofrequency Ablation for Appropriately Selected Patients
If temporarily blocking the medial branch nerves produces the required relief of the patient’s typical pain, the response can provide evidence that the corresponding facet joints are contributing to symptoms.
For appropriately selected patients, lumbar radiofrequency ablation (RFA) may then be considered to provide longer-lasting reduction of facet-mediated pain.
Learn More About Lumbar Radiofrequency Ablation
Who Is a Candidate for a Lumbar Facet Joint Injection?
A lumbar facet joint injection may be considered when symptoms and clinical findings suggest facet-mediated low back pain.
Potential candidates may include patients who:
- Have persistent lower back pain
- Have lumbar facet arthritis
- Have lumbar spondylosis
- Experience pain with back extension or rotation
- Have referred pain into the buttock or upper thigh
- Have persistent symptoms despite appropriate conservative care
- Have symptoms consistent with facet-mediated pain
Treatment selection should be based on the patient’s clinical presentation rather than imaging findings alone.
When Is a Lumbar Facet Injection Not the Right Treatment?
Low back pain can originate from many different structures.
If symptoms are caused primarily by lumbar radiculopathy or sciatica, treatment directed toward an irritated spinal nerve may be more appropriate.
Learn More About Lumbar Radiculopathy (Sciatica)
If pain is caused by sacroiliac joint dysfunction, treatment should instead focus on the SI joint.

Other possible sources include discs, muscles, spinal stenosis, and additional musculoskeletal structures.
The goal is to identify the pain generator before selecting an injection.
How Long Do Lumbar Facet Joint Injections Last?
The duration of improvement varies.
Local anesthetic generally provides temporary effects, while corticosteroid medication may provide longer-lasting relief for some patients.
Some patients experience improvement for weeks or longer, while others experience limited or no benefit.
Facet injections do not permanently reverse degenerative changes within the spine.
For patients with confirmed chronic facet-mediated pain, other treatment options may be considered when symptoms recur.
How Quickly Do Lumbar Facet Joint Injections Work?
If local anesthetic is used, some patients may notice temporary improvement relatively soon after the procedure.
The anti-inflammatory effects of corticosteroid medication may take several days to become more noticeable.
Temporary soreness around the injection area may occur.
Patients should follow the post-procedure instructions provided by their physician.
Are Lumbar Facet Joint Injections Safe?
Lumbar facet injections are minimally invasive procedures, but all medical procedures have potential risks.
Potential risks and side effects may include:
- Temporary injection-site soreness
- Temporary increase in pain
- Bleeding
- Infection
- Medication-related effects
- Allergic reaction
- Nerve irritation or injury
- Other uncommon complications
Patients taking blood-thinning medications or those with certain medical conditions may require additional planning before treatment.
Potential risks, benefits, and alternatives should be discussed individually.
What Is Recovery Like?
Lumbar facet joint injections are generally performed on an outpatient basis.
Patients are monitored after treatment and receive individualized instructions regarding activity and recovery.
Temporary soreness may occur around the injection site.
When pain improves, treatment may be combined with:
- Physical therapy
- Core strengthening
- Mobility exercises
- Activity modification
- Appropriate exercise
- Ergonomic adjustments
The goal is to improve pain while supporting long-term mobility and function.
Lumbar Facet Joint Injections at TOPS Institute
Lower back pain can originate from discs, nerves, muscles, the sacroiliac joints, or the facet joints.
At TOPS Institute, we take a diagnosis-driven approach rather than treating all lower back pain the same way.
For suspected facet-mediated pain, we evaluate:
- Location and pattern of symptoms
- Movements that reproduce pain
- Range of motion
- Neurological findings
- Relevant imaging
- Previous treatments
before determining whether a lumbar facet joint injection or another procedure is appropriate.
When radiofrequency ablation is being considered, diagnostic lumbar medial branch blocks may be used to determine whether the facet joints are contributing to the patient’s pain.
For patients seeking lumbar facet joint injections in Los Angeles or Beverly Hills, TOPS Institute provides personalized interventional pain management focused on identifying the pain generator and selecting targeted treatment.

Frequently Asked Questions About Lumbar Facet Joint Injections
What is a lumbar facet joint injection?
A lumbar facet joint injection is a minimally invasive procedure in which medication is delivered directly into one of the facet joints in the lower spine. It may be considered when a facet joint is suspected of contributing to chronic low back pain.
What does lumbar facet joint pain feel like?
Facet-mediated pain often causes aching lower back pain and stiffness. Symptoms may worsen with standing, extension, or rotation and can sometimes refer into the buttocks, hips, or upper thighs.
Can lumbar arthritis cause facet joint pain?
Yes. Lumbar spondylosis can involve degeneration of the facet joints. However, arthritis visible on imaging does not necessarily mean the joint is causing pain, so clinical evaluation remains important.
Learn More About Lumbar Spondylosis (Back Arthritis)
Can facet joint pain cause sciatica?
Facet-mediated pain may refer into the buttock or upper thigh, but classic sciatica typically results from irritation or compression of a lumbar spinal nerve root and may extend farther down the leg.
Learn More About Lumbar Radiculopathy (Sciatica)
What is the difference between a lumbar facet injection and an epidural?
A facet injection targets a spinal joint. A lumbar epidural steroid injection delivers medication into the epidural space surrounding spinal nerves and is more commonly used for nerve-related symptoms such as lumbar radiculopathy.
Learn More About Lumbar Epidural Steroid Injections
What is the difference between a lumbar facet injection and a medial branch block?
A facet injection places medication directly into the joint. A medial branch block temporarily numbs the nerves that carry pain signals from the facet joints and is commonly used diagnostically when radiofrequency ablation is being considered.
Learn More About Lumbar Medial Branch Blocks
How long do lumbar facet joint injections last?
Results vary. Some patients experience improvement for weeks or longer, while others have limited relief. The duration depends on the underlying condition and individual response.
Do lumbar facet injections cure back arthritis?
No. Facet joint injections do not reverse arthritis or restore damaged cartilage. They are intended to help manage pain associated with the affected joint.
What happens if lumbar facet pain keeps returning?
If facet-mediated pain is confirmed and symptoms continue, lumbar medial branch blocks may be used to determine whether radiofrequency ablation is appropriate. For selected patients, lumbar RFA may provide longer-lasting relief by interrupting pain signals from the affected facet joints.
