Medial Branch Block

Targeted Diagnosis and Relief for Facet Joint-Related Spinal Pain

A Medial Branch Block is a minimally invasive, image-guided procedure used to assess and manage pain arising from the facet joints of the spine. Using fluoroscopy for precise needle placement, a small amount of local anaesthetic is delivered near the medial branch nerves that carry pain signals from these joints.

What Is a Medial Branch Block?

A Medial Branch Block is an image-guided injection procedure used when the small facet joints of the spine are suspected to be a source of back or neck pain.

Facet joints are small joints located at the back of the spine. They help provide stability and allow controlled movement between adjacent vertebrae. The medial branch nerves carry sensory pain signals from these joints.

During a medial branch block, a pain specialist uses fluoroscopy, a real-time X-ray imaging technique, to guide a fine needle to the appropriate medial branch nerve. A small amount of local anaesthetic is then injected near the targeted nerve.

The procedure may be used to determine whether the targeted facet joints are contributing to your pain. If significant temporary pain relief occurs after an appropriately performed diagnostic block, your specialist may consider whether a further treatment, such as radiofrequency ablation, could be appropriate.

The Procedure

How Does a Medial Branch Block Work?

01
Clinical Assessment

Your specialist reviews your symptoms, medical history, physical examination and relevant imaging to determine whether facet-mediated pain is a possible contributor.

02
Patient Positioning

You are positioned appropriately on the procedure table so the specialist can safely access the targeted medial branch nerves.

03
Fluoroscopy Guidance

Real-time fluoroscopic imaging is used to identify the relevant spinal anatomy and guide the needle toward the selected medial branch nerve.

04
Targeted Injection

After appropriate needle positioning is confirmed, a small amount of local anaesthetic is delivered near the targeted medial branch nerve.

Potential Benefits of Medial Branch Block
Targeted Pain Assessment

The procedure can help determine whether pain from specific facet joints is contributing to your symptoms.

Potential Temporary Relief

Local anaesthetic may provide temporary reduction in pain from the targeted area.

Image-Guided Precision

Fluoroscopy provides real-time visualization to help guide the needle to the intended anatomical location.

Helps Guide Treatment Planning

The response to a diagnostic block may help your specialist determine whether additional facet-related treatment should be considered.

Minimally Invasive

The procedure uses a fine needle and does not require open surgery.

Usually Short Procedure

Medial branch blocks are generally performed as a minimally invasive outpatient procedure, depending on individual circumstances.

A medial branch block does not guarantee long-term pain relief. Its diagnostic value and duration of symptom relief vary between patients.
You May Be a Candidate If:

A medial branch block may be considered when your symptoms and clinical assessment suggest that the facet joints may be contributing to your spinal pain.

Your doctor may consider the procedure if:

  • You have persistent neck or back pain that may be related to the facet joints.
  • Your pain pattern and physical examination suggest possible facet-mediated pain.
  • Conservative treatments have not provided sufficient improvement.
  • Your symptoms are appropriate for a diagnostic medial branch block.
  • Relevant imaging and clinical findings have been reviewed when necessary.
  • Your overall health permits the procedure to be performed safely.
A medial branch block is not appropriate for every type of back or neck pain. Your specialist will assess the likely pain source before recommending the procedure.

Conditions Where Medial Branch Block May Be Considered

Medial branch blocks are primarily considered when the facet joints are suspected to be a source of spinal pain. The exact treatment level depends on your symptoms, examination and clinical assessment.

Cervical Facet Pain

A medial branch block may be considered when facet joints in the neck are suspected to contribute to persistent neck pain.

Thoracic Facet Pain

In selected patients, medial branch blocks may be used to assess pain suspected to originate from facet joints in the mid-back.

Lumbar Facet Pain

Lumbar medial branch blocks may be considered when facet joints are suspected to contribute to chronic lower back pain.

Spinal Spondylosis

Degenerative changes in the spine can affect the facet joints. A block may be considered when these joints are clinically suspected to be painful.

Facet Joint Syndrome

The procedure can help assess whether selected facet joints are contributing to a patient's spinal pain.

Chronic Axial Spinal Pain

In carefully selected cases, medial branch blocks may help evaluate facet joints as a possible source of persistent axial neck or back pain.

Before Medial Branch Block

Before your procedure, your pain specialist may:

  • Review your symptoms and medical history.
  • Perform a focused spinal and neurological examination.
  • Assess whether your pain pattern may be consistent with facet-mediated pain.
  • Review relevant MRI, CT, X-ray or other investigations when required.
  • Review previous treatments and their response.
  • Review medications, allergies and relevant medical conditions.
  • Discuss the purpose of the block, expected response, limitations and possible risks.
  • Provide instructions regarding medicines, eating, drinking or other preparation when applicable.

Your specialist will determine which medial branch nerves should be targeted based on your clinical assessment.

After Medial Branch Block

After the procedure, you may be monitored briefly before being discharged, depending on your clinical condition and the type of procedure performed.

You may be advised to:

  • Follow the activity instructions provided by your doctor.
  • Avoid strenuous activity immediately after the procedure if advised.
  • Monitor your pain response during the period specified by your specialist.
  • Record the degree and duration of pain relief when instructed, particularly when the block is being used diagnostically.
  • Continue your prescribed treatment or rehabilitation programme as advised.
  • Attend follow-up appointments to discuss your response to the block.

The duration and degree of pain relief can vary. A diagnostic medial branch block is often interpreted based on the amount and timing of pain relief relative to the patient's usual pain pattern.

Risks & Considerations

Medial Branch Block is generally considered a minimally invasive procedure, but like any injection procedure it has potential risks and complications.

Possible effects include temporary soreness or bruising at the injection site, bleeding, infection, temporary numbness or weakness, and discomfort during or after the procedure.

Fluoroscopy uses a small amount of ionizing radiation. The procedure is performed using appropriate imaging techniques to limit radiation exposure while obtaining the necessary views.

Allergic or adverse reactions to medicines or contrast material can occur in some patients. Relevant allergies and medical conditions should therefore be discussed with your doctor before the procedure.

A medial branch block is not a guaranteed source of long-term pain relief. Its primary purpose may be diagnostic, although temporary therapeutic relief can also occur.

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 after the procedure.

Frequently Asked Questions

What is a Medial Branch Block?
A Medial Branch Block is an image-guided procedure in which local anaesthetic is placed near the medial branch nerves that carry pain signals from the spinal facet joints.
Why is a Medial Branch Block performed?
It may be performed to assess whether specific facet joints are contributing to neck or back pain. It can also provide temporary pain relief in some patients.
Is a Medial Branch Block the same as a facet joint injection?
No. A medial branch block targets the small medial branch nerves associated with the facet joints, while a facet joint injection places medication directly into or around the facet joint.
Is the procedure performed under fluoroscopy?
Yes. Fluoroscopy is commonly used to provide real-time X-ray guidance during a medial branch block and to assist with accurate needle placement.
Is a Medial Branch Block painful?
You may feel a brief sting from the local anaesthetic, pressure or temporary discomfort during the procedure. The experience varies between patients.
How long does a Medial Branch Block take?
The injection itself is generally brief, although the total appointment includes preparation, positioning, imaging, the procedure and post-procedure observation.
How soon can I know whether the block worked?
When local anaesthetic is used diagnostically, pain relief may occur relatively soon after the injection. Your doctor may ask you to monitor and record your pain response over a specified period.
How long does pain relief from a Medial Branch Block last?
The duration varies considerably. Because the local anaesthetic is temporary, relief from a diagnostic block may also be temporary. Your specialist will interpret the response in the context of your symptoms and treatment plan.
What happens if the Medial Branch Block provides significant relief?
If the response supports the facet joints as a likely pain source, your specialist may discuss additional treatment options. In appropriately selected patients, radiofrequency ablation of the medial branch nerves may be considered.
Are there risks associated with a Medial Branch Block?
Possible risks include temporary soreness, bruising, bleeding, infection, temporary numbness or weakness, medication reactions and other complications. Your doctor will discuss the risks relevant to your individual circumstances before treatment.

Could Your Facet Joints Be Causing Your Back or Neck Pain?

Persistent spinal pain can have several possible sources. If your clinical assessment suggests that the facet joints may be contributing to your symptoms, a Medial Branch Block may help your specialist evaluate the suspected pain source.
