Facet Block

What is a Facet Joint Block?

A Facet Joint Block is a minimally invasive, image-guided injection used to diagnose and treat pain arising from the small joints of the spine known as facet joints. These joints connect the vertebrae and help provide stability while allowing controlled movement of the neck and back.

With ageing, arthritis, injury, or repetitive stress, the facet joints can become inflamed and painful. This may result in persistent neck pain, back pain, stiffness, and difficulty performing daily activities. A Facet Joint Block involves injecting a local anaesthetic, often combined with a corticosteroid, directly into or around the affected joint to reduce inflammation and relieve pain.

The procedure can serve both diagnostic and therapeutic purposes. If pain improves significantly after the injection, it confirms that the facet joint is the primary source of symptoms. This information also helps determine whether additional treatments, such as radiofrequency ablation, may be beneficial.

Dr. Yadhu K Lokanath, Consultant Neurosurgeon and Spine Surgeon in Bangalore, carefully evaluates each patient before recommending a Facet Joint Block as part of a comprehensive spine care plan.

What Conditions Can Facet Joint Blocks Treat?

Facet Joint Blocks may be recommended for:

• Cervical facet joint arthritis
• Lumbar facet joint arthritis
• Thoracic facet joint pain
• Degenerative spine disease
• Chronic neck pain
• Chronic lower back pain
• Whiplash-related neck pain
• Pain after spinal injury
• Pain following previous spine surgery
• Mechanical back pain
• Persistent spinal pain that has not improved with conservative treatment

The procedure is most effective when pain originates from the facet joints rather than a compressed spinal nerve.

What is the Anatomy Involved?

Facet joints are paired joints located at the back of each vertebra. They guide spinal movement while helping maintain stability.

Important structures involved include:

• Cervical, thoracic, and lumbar facet joints
• Vertebrae
• Joint capsule
• Cartilage
• Medial branch nerves
• Ligaments
• Paraspinal muscles

Inflammation or degeneration of these joints may lead to localized pain and stiffness. A Facet Joint Block delivers medication directly to the affected joint or its surrounding tissues under imaging guidance.

What are the Symptoms?

Patients with facet joint pain commonly experience:

• Neck pain or lower back pain
• Pain that worsens with standing or walking
• Pain during twisting or bending
• Morning stiffness
• Pain after prolonged sitting
• Tenderness over the affected spinal joints
• Reduced spinal flexibility
• Muscle tightness
• Pain extending to the shoulder, buttock, or thigh without significant numbness
• Difficulty performing routine activities

Unlike nerve-root compression, facet joint pain usually does not cause severe radiating pain below the knee or into the hand.

When Should I See a Spine Surgeon?

Consult a spine surgeon if spinal pain persists despite medication, physiotherapy, exercise, or lifestyle modification.

Seek immediate medical evaluation if pain is associated with:

• Progressive arm or leg weakness
• Loss of bladder or bowel control
• Numbness around the genital area
• Severe pain after trauma
• Fever with back pain
• Unexplained weight loss
• Difficulty walking because of neurological symptoms

These signs may indicate a condition that requires further investigation rather than a facet injection alone.

How is the Condition Diagnosed?

Diagnosis begins with a detailed assessment of symptoms and physical examination.

Investigations may include:

• Medical history
• Physical examination
• Neurological examination
• MRI of the spine
• CT scan
• X-rays
• Dynamic flexion-extension X-rays
• Diagnostic Facet Joint Block

Because imaging findings do not always correlate with pain, a diagnostic injection is often the most reliable method to confirm the facet joint as the pain source.

Can It Be Managed Without Injection?

Many patients improve with conservative treatment, including:

• Activity modification
• Physiotherapy
• Core-strengthening exercises
• Posture correction
• Weight management
• Heat or ice therapy
• Ergonomic improvements
• Regular stretching

These measures may reduce symptoms but may not adequately control chronic facet joint inflammation.

What are the Non-Surgical Treatment Options?

Before or alongside a Facet Joint Block, treatment may include:

Medications

Anti-inflammatory medicines, pain relievers, and muscle relaxants may help reduce pain and stiffness.

Physiotherapy

Targeted exercises improve spinal mobility, flexibility, posture, and muscle strength.

Lifestyle Modification

Maintaining a healthy weight, avoiding repetitive strain, and practicing proper lifting techniques help reduce stress on the facet joints.

Rehabilitation

A structured rehabilitation programme supports long-term spinal function and helps prevent recurrence.

All medications should be used only under medical supervision.

When is a Facet Joint Block Recommended?

A Facet Joint Block may be considered when:

• Neck or back pain persists despite conservative treatment
• Clinical examination suggests facet joint pain
• MRI or X-rays show facet joint degeneration
• Pain limits daily activities
• The doctor needs to confirm the source of pain
• Radiofrequency ablation is being considered after a successful diagnostic block

How is the Procedure Performed?

The procedure is performed under sterile conditions using fluoroscopic (X-ray) or CT guidance.

After cleaning and numbing the skin, a fine needle is guided into the affected facet joint or around the medial branch nerves. A small amount of local anaesthetic and corticosteroid is then injected.

The procedure usually takes 15 to 30 minutes, and most patients return home the same day.

Recovery and Possible Risks

Most patients resume light activities within 24 hours. Mild soreness at the injection site is common and usually settles within a day or two.

Possible risks include:

• Temporary soreness
• Infection
• Bleeding
• Allergic reaction
• Temporary numbness
• Increased pain for a short period
• Steroid-related side effects
• Rare nerve injury

Pain relief varies between patients. Some experience relief lasting several weeks or months, while others may require additional treatment or rehabilitation.

Frequently Asked Questions

Is a Facet Joint Block painful?

Most patients experience only mild discomfort because the skin is numbed before the injection.

Is the procedure a permanent cure?

No. It helps reduce inflammation and confirm the pain source but does not reverse arthritis or spinal degeneration.

How long does pain relief last?

Relief may last from several weeks to several months, depending on the underlying condition.

Can I walk after the injection?

Yes. Most patients are able to walk shortly after the procedure.

How many Facet Joint Blocks can I receive?

The number depends on your diagnosis, response to treatment, and your doctor’s recommendations.

What if the injection works only temporarily?

If a diagnostic block provides good but temporary relief, procedures such as Radiofrequency Ablation (RFA) may be considered for longer-lasting pain control.

Book an Appointment

Persistent neck pain or lower back pain caused by facet joint arthritis can significantly affect your mobility and quality of life. When medication, physiotherapy, and lifestyle changes are not enough, a Facet Joint Block may help identify the source of pain and provide meaningful relief.
