Overview
A cervical facet joint block is a targeted procedure used to diagnose and treat pain arising from the small joints at the back of the neck. The facet joints help guide movement and stabilise the cervical spine. When these joints become irritated due to arthritis, repetitive strain, posture related stress, or injury, they may cause localised neck pain and stiffness.
Pain from the facet joints may also spread into the shoulders or upper back. A cervical facet joint block delivers medication directly to the affected joint or to the nerves that carry pain signals from the joint. The aim is to reduce irritation, calm pain signals, and support improved neck movement.
This procedure can also help confirm whether the facet joints are the main source of symptoms before considering longer term treatment options.
Who this treatment helps
A cervical facet joint block may be considered for people with:
- Localised neck pain made worse by turning or bending
- Stiffness or aching at the back of the neck
- Pain following whiplash injury or repetitive strain
- Discomfort spreading into the shoulders or upper back
- Symptoms linked to facet joint irritation on examination or imaging
- Persistent pain despite physiotherapy or medication
A specialist consultation is required to confirm suitability and rule out other causes of neck pain.
What is a cervical facet joint block
A cervical facet joint block involves placing a small amount of local anaesthetic, sometimes combined with steroid medication, into or around the facet joints. In many cases the medication is placed near the medial branch nerves. These tiny nerves carry pain signals from the facet joints to the brain.
Imaging guidance such as fluoroscopy using X ray, or ultrasound in some cases, may be used to support accurate placement of the needle.
The procedure can serve two purposes:
- Diagnostic: helps determine whether the facet joints are the main source of pain
- Therapeutic: may reduce inflammation and improve symptoms
If the block provides clear short term relief, your consultant may discuss radiofrequency treatment as a longer lasting option for controlling facet joint pain.
What to expect during the procedure
Your consultant will review the treatment plan and answer any final questions before the procedure begins.
- You lie comfortably on the procedure table
- The skin over the neck is cleaned and numbed with local anaesthetic
- A fine needle is guided to the facet joint or medial branch nerve using imaging guidance where appropriate
- A small amount of medication is injected
- You rest briefly before going home
The procedure usually takes around 10 to 20 minutes.
After the procedure
After a cervical facet joint block, mild soreness at the injection site is common and usually settles within a short time.
- Temporary numbness or warmth in the neck may occur
- Some people notice improvement within hours
- Others may take a few days to experience relief
- Normal activities can usually be resumed the same day
- Strenuous exercise should be avoided for about 24 hours
Your consultant may also recommend physiotherapy, posture advice, or follow up treatments depending on your response.
Benefits
- May reduce neck pain linked to facet joint irritation
- Helps confirm whether the facet joints are the source of symptoms
- Can improve movement and daily comfort
- May reduce reliance on medication
- Minimally invasive with a short recovery period
- Can guide future treatment planning including radiofrequency procedures
Possible risks and side effects
Cervical facet joint blocks are generally safe when performed by experienced clinicians, but all procedures carry some risk.
- Temporary numbness or mild weakness
- Local soreness or bruising
- Light headedness
- Temporary increase in pain
- Infection which is rare
- Bleeding which is uncommon
Your consultant will discuss the potential risks and expected benefits during your assessment.
When to consider other options
If symptoms persist or the block provides limited benefit, your consultant may discuss other treatments such as cervical epidural steroid injection or trigger point injection. Physiotherapy, rehabilitation programmes, medication review, or combined treatment approaches may also be recommended depending on the diagnosis.
Safety note
Please inform your consultant if you take blood thinners, have allergies, diabetes, active infection, are pregnant, or have had previous reactions to local anaesthetic. Depending on the medication used, you may also need someone to drive you home after the procedure.
Arrange a consultation to discuss whether a cervical facet joint block may be appropriate for your symptoms.
