What Is a Lumbar Facet Block?

A Lumbar Facet Block is an image-guided injection procedure used when one or more facet joints in the lower spine are suspected to be contributing to persistent low back pain.

Facet joints are small paired joints located at the back of the lumbar vertebrae. They help stabilise the spine and guide its movement. Degenerative changes, inflammation, injury or mechanical stress can sometimes make these joints painful.

During a lumbar facet block, your pain specialist uses fluoroscopy, a real-time X-ray imaging technique, to identify the targeted facet joint and guide a fine needle into the appropriate position.

A small amount of medication, which may include a local anaesthetic and corticosteroid depending on the clinical situation, can then be delivered into or around the joint. The procedure may provide temporary pain relief and can also help assess whether the targeted facet joint is a significant source of your symptoms.

The Procedure

How Does a Lumbar Facet Block Work?

01
Clinical Assessment

Your specialist reviews your symptoms, medical history, examination findings and relevant investigations to assess whether the lumbar facet joints may be contributing to your pain.

02
Positioning

You are positioned on the procedure table in a way that allows safe access to the selected lumbar facet joint.

03
Fluoroscopy Guidance

Real-time X-ray imaging is used to identify the relevant spinal anatomy and guide the needle toward the targeted facet joint.

04
Targeted Injection

Once the needle position is confirmed, the selected medication is delivered into or around the targeted lumbar facet joint.

Potential Benefits of Lumbar Facet Block
Targeted Treatment

Medication is delivered directly to the suspected painful facet joint rather than treating the entire body.

Potential Pain Relief

The local anaesthetic may provide short-term pain relief, while an appropriate steroid may help reduce inflammation in selected patients.

Image-Guided Precision

Fluoroscopy provides real-time visualization to help guide the needle toward the intended facet joint.

Diagnostic Information

The response to the injection may provide useful information about whether the targeted facet joint is contributing to your pain.

Minimally Invasive

The procedure is performed through a fine needle and does not require open surgery.

May Support Rehabilitation

When pain is reduced, some patients may be better able to participate in prescribed physical therapy and rehabilitation.

The degree and duration of pain relief vary between patients. A lumbar facet block does not guarantee permanent pain relief.
You May Be a Candidate If:

A lumbar facet block may be considered when your clinical assessment suggests that one or more lumbar facet joints could be contributing to your lower back pain.

Your doctor may consider the procedure if:

  • You have persistent or chronic lower back pain.
  • Your symptoms and examination suggest possible facet joint involvement.
  • Conservative treatments have not provided adequate improvement.
  • Relevant imaging or other investigations have been reviewed when clinically required.
  • Your doctor believes a targeted facet injection may provide useful diagnostic or therapeutic information.
  • Your overall health allows the procedure to be performed safely.
Not all lower back pain comes from the facet joints. Your specialist will evaluate other possible pain sources before recommending a lumbar facet block.

Conditions Where Lumbar Facet Block May Be Considered

Lumbar facet blocks are considered in selected patients when clinical findings suggest that the facet joints may be contributing to lower back pain.

Lumbar Facet Joint Pain

A facet block may be considered when one or more lumbar facet joints are suspected to be a source of localized lower back pain.

Lumbar Spondylosis

Degenerative changes in the lumbar spine can affect the facet joints and may contribute to mechanical lower back pain.

Lumbar Facet Syndrome

In selected cases, facet blocks may be used to assess and manage pain believed to originate from the lumbar facet joints.

Chronic Axial Low Back Pain

A lumbar facet block may be considered as part of the assessment of persistent axial low back pain when facet involvement is suspected.

Degenerative Facet Changes

Age-related or degenerative changes affecting the lumbar facet joints may contribute to mechanical spinal pain in some patients.

Mechanical Low Back Pain

In carefully selected cases, facet joint involvement may be evaluated when back pain changes with certain spinal movements or loading.

Before Lumbar Facet Block

Before your procedure, your pain specialist may:

  • Review your symptoms, medical history and previous treatments.
  • Perform a focused physical and neurological examination.
  • Assess whether your symptoms may be related to the lumbar facet joints.
  • Review relevant X-rays, MRI, CT or other investigations when clinically required.
  • Review your current medications and allergies.
  • Discuss the expected benefits, limitations, alternatives and potential risks.
  • Explain any specific preparation instructions before the procedure.

Your doctor will determine whether a lumbar facet block is appropriate based on your individual condition.

After Lumbar Facet Block

After the procedure, you may be monitored for a short period before discharge. Your post-procedure instructions will depend on your individual condition and the medications used.

You may be advised to:

  • Follow the activity instructions provided by your doctor.
  • Avoid strenuous activity for the period recommended by your specialist.
  • Monitor your pain and other symptoms after the injection.
  • Record your response to the treatment if your doctor has asked you to monitor pain relief.
  • Continue prescribed exercises or rehabilitation when recommended.
  • Attend follow-up appointments as advised.

Some patients may experience relief relatively soon because of the local anaesthetic, while the response to any corticosteroid used may take longer. The amount and duration of relief vary from person to person.

Risks & Considerations

Lumbar Facet Block is a minimally invasive procedure, but it can still have potential risks and side effects.

Possible complications include temporary pain or soreness at the injection site, bruising, bleeding, infection, temporary numbness or weakness and reactions to the injected medication.

If corticosteroids are used, temporary changes in blood glucose, flushing or other steroid-related effects may occur in some patients.

Fluoroscopy uses ionizing radiation. The amount used during a procedure is kept as low as reasonably achievable while obtaining the imaging needed for safe needle placement.

A lumbar facet block does not guarantee permanent pain relief. It may be used for diagnostic information, temporary symptom relief, or both, depending on the clinical situation.

Seek medical attention promptly if you develop severe or worsening pain, significant weakness, persistent numbness, fever, spreading redness or swelling, difficulty breathing, or other concerning symptoms following the procedure.

Frequently Asked Questions

What is a Lumbar Facet Block?
A Lumbar Facet Block is an image-guided injection procedure that delivers medication into or around a selected facet joint in the lower spine to assess or manage facet-related pain.
Why is a Lumbar Facet Block performed?
It may be performed when a lumbar facet joint is suspected to be contributing to lower back pain. The procedure can provide temporary relief and may also provide diagnostic information.
Is a Lumbar Facet Block the same as a Medial Branch Block?
No. A lumbar facet block targets the facet joint itself or its immediate vicinity, whereas a medial branch block targets the medial branch nerves that carry sensory signals from the facet joint.
Is a Lumbar Facet Block performed under fluoroscopy?
Yes. Fluoroscopy is commonly used to provide real-time X-ray guidance and help the specialist accurately position the needle at the targeted lumbar facet joint.
