Axial spine pain
Pain is often centered in the neck or low back rather than dominated by a classic nerve-root pattern into an arm or leg.
FACET JOINT PAIN
When the small joints of the spine become a source of pain.
Facet joints help guide and stabilize movement of the spine. Degenerative or arthritic changes in these joints can contribute to axial neck or back pain—but identifying a painful facet joint requires more than seeing arthritis on imaging.
UNDERSTANDING FACET PAIN
Arthritis on an MRI does not automatically mean the facet joint hurts.
Facet joints are paired joints located along the back of the spine. Like other joints, they can develop degenerative changes over time and may become a source of pain in selected patients.
Facet degeneration is common on imaging, including in people without facet-mediated pain. The diagnosis therefore depends on the clinical picture and, when appropriate, carefully performed diagnostic medial branch blocks rather than imaging findings alone.
COMMON FEATURES
How facet-mediated pain may present.
There is no single symptom or examination finding that proves pain is coming from a facet joint. Certain patterns can raise suspicion and help guide a focused evaluation.
Movement-related pain
Extension, rotation, prolonged standing, or other spinal movements may aggravate symptoms in some patients.
Localized tenderness
Some patients have tenderness over the affected region, although tenderness by itself is not diagnostic.
Referred pain
Facet-mediated pain may refer into nearby regions, but the distribution can overlap with other spinal and musculoskeletal conditions.
DIAGNOSTIC MEDIAL BRANCH BLOCKS
Test the nerve supply before treating it.
The medial branch nerves carry pain signals from the facet joints. When facet-mediated pain is suspected, a small amount of local anesthetic can be placed near these nerves using image guidance to assess whether temporarily interrupting that signal meaningfully reduces the patient’s typical pain.
A medial branch block is primarily a diagnostic or prognostic test in this setting. The degree and duration of relief are interpreted alongside the patient’s usual activities, examination, and overall clinical picture when deciding whether radiofrequency ablation may be appropriate.
DIAGNOSIS
Diagnosis is clinical—and confirmation is functional.
No history, physical examination maneuver, or imaging finding can reliably identify a painful facet joint on its own. A focused evaluation helps rule in or rule out competing pain generators, while appropriately selected diagnostic blocks can provide additional information about whether the facet joint nerve supply is contributing meaningfully to the patient’s pain.
Imaging has limitsDegenerative facet changes are common and do not necessarily identify the source of pain.
Blocks add informationResponse to image-guided medial branch blocks can help determine whether facet-directed treatment is appropriate.
Function mattersResponse should be interpreted during the activities that normally provoke the patient’s pain.
TREATMENT
Treatment follows the diagnosis.
Conservative care
Treatment may include activity modification, therapeutic exercise or physical therapy, and appropriate medication strategies based on the individual clinical situation.
Medial branch blocks
For selected patients, image-guided diagnostic medial branch blocks can help determine whether the facet joint nerve supply is contributing to the patient’s typical pain.
Radiofrequency ablation
When diagnostic testing and the overall clinical picture support facet-mediated pain, radiofrequency ablation may be considered to interrupt pain signaling through the targeted medial branch nerves.
FREQUENTLY ASKED QUESTIONS
Common questions about facet joint pain.
Can an MRI tell whether my facet joints are causing pain?
Not by itself. Imaging can show facet degeneration or arthritis, but these findings are common and do not necessarily identify the source of pain. The diagnosis depends on the overall clinical picture and, in selected patients, the response to diagnostic medial branch blocks.
Is a medial branch block the same as a facet joint injection?
No. A medial branch block targets the small nerves that carry pain signals from the facet joints, while an intra-articular facet injection places medication directly into the joint. They are different procedures with different diagnostic and therapeutic roles.
What happens if a medial branch block helps?
A meaningful temporary response can provide evidence that the targeted facet joint nerve supply is contributing to the patient’s typical pain. Depending on the overall clinical picture, response to diagnostic testing, and applicable treatment criteria, radiofrequency ablation may then be considered.
Does radiofrequency ablation permanently destroy the nerve?
Radiofrequency ablation uses controlled thermal energy to interrupt pain signaling through the targeted medial branch nerve. The nerve can regenerate over time, so pain relief is not necessarily permanent and symptoms may eventually return.
Is facet pain the same as a pinched nerve or sciatica?
No. Facet-mediated pain is typically an axial or referred pain problem involving the facet joints and their nerve supply. Radiculopathy or sciatica involves irritation or dysfunction of a spinal nerve root and may produce radiating pain, numbness, tingling, or weakness in an arm or leg.
NEXT STEP
Could the facet joints be contributing to your pain?
A focused evaluation can help determine whether facet-mediated pain fits your clinical picture and whether diagnostic medial branch blocks, radiofrequency treatment, or other treatment options may be appropriate.
