Facet joint syndrome means pain attributed to the small joints connecting vertebrae at the back of the spine, also called facet arthropathy or facet joint arthritis.[1] It describes a suspected pain source, not a treatment plan: Mayfield Brain & Spine (2018) describes confirming it with a history, an exam and often a diagnostic injection, and two Framingham CT studies show a scan alone does not settle it.[3][4]

Key takeaways
- Mayfield Brain & Spine (2018) describes facet joint syndrome as most common between ages 40 and 70, usually a dull ache over the spine that worsens with bending backward or twisting.[1]
- Kalichman and colleagues (2008) found no significant adjusted association between CT facet arthritis and low back pain, while Suri and colleagues (2013) reported an adjusted odds ratio of 2.15 for severe facet osteoarthritis and frequent pain.[3][4]
- A facet joint injection places medication into the joint, a medial branch block numbs the nerves that serve it, and radiofrequency ablation uses current on those nerves.[1][2]
- NICE guideline NG59 advises against spinal injections for managing low back pain and allows radiofrequency denervation only after a positive diagnostic medial branch block.[5]
- PRP for facet joint pain is off label, usually cash pay and thinly studied, and a PRP directory listing does not establish spine expertise.
Where are the facet joints, and what is facet arthropathy?
Facet joints sit behind the spinal discs, linking neighboring vertebrae.[1] Their surfaces have cartilage, fluid and a surrounding capsule.[1] Mayfield Brain & Spine uses facet arthropathy alongside facet joint syndrome in its September 2018 patient guide.[1]
Facet joints are paired and occur in the cervical, thoracic and lumbar spine. Mayfield describes wear that thins the capsule, roughens the cartilage and can form bone spurs, with pain carried by small capsule nerves called medial branch sensory nerves.[1]
That guide describes pain in the back or neck and notes overlap with other spinal conditions.[1] Its evaluation description includes medical history, examination and possible imaging.[1] These terms are not a self-diagnosis checklist.
What are the symptoms of facet joint syndrome?
Facet joint pain is typically a dull, diffuse ache directly over the spine, according to Mayfield Brain & Spine (2018).[1] Low back pain can spread to the buttocks, and neck pain to the shoulders and back of the skull; bending backward, twisting or standing tends to worsen it, while sitting or leaning forward eases it.[1] Because it can mimic a disc herniation, clinicians also weigh sacroiliac joint pain and nerve root pain such as sciatica.[1]
How is facet joint syndrome diagnosed?
Facet joint syndrome is diagnosed by combining a medical history, a physical exam and, in many cases, a diagnostic injection, according to Mayfield (2018).[1] X-ray, CT or MRI may be ordered to check for other spine and hip problems, and Mayfield states that no change in pain after a diagnostic injection makes the facet joint an unlikely source.[1]
NICE guideline NG59 advises against routine imaging for low back pain outside specialist settings, and suggests it in specialist care only when the result is likely to change management.[5] Clinicians involved often include primary care physicians, physiatrists, pain medicine specialists, interventional radiologists, physical therapists and spine surgeons.
Does facet arthritis on a scan explain back pain?
The 2008 and 2013 Framingham-based observational studies reported different findings.[3][4] Neither tested a treatment.[3][4]
Kalichman and colleagues' November 2008 cross-sectional study included 188 community participants.[3] CT assessments covered lumbar levels L2-S1, using at least moderate osteoarthritis as the threshold.[3] The pain questionnaire asked about low back pain on most days of at least one month during the preceding year.[3]
The study recorded qualifying facet osteoarthritis in 62 of 104 men and 56 of 84 women.[3] Its adjusted analyses found no statistically significant association between the imaging finding and the reported low back pain outcome.[3] That is the finding in this sample, not proof that facet joints never cause pain.
Suri and colleagues' September 2013 study examined 252 older adults, with a mean age of 67.4 years.[4] It specifically assessed severe facet osteoarthritis and back pain on most or all days during the previous year.[4] The pain interview occurred an average of 20 months after the CT scan.[4]
Severe facet osteoarthritis appeared in 63.2 percent of participants with frequent pain and 46.7 percent without frequent pain.[4] The adjusted odds ratio was 2.15, with a 95 percent confidence interval of 1.13 to 4.08.[4] The comparison group included people with pain on a few or some days, not only pain-free people.[4]
The populations, arthritis thresholds and pain definitions differ.[3][4] These observational results should not be flattened into either 'scans prove the pain source' or 'arthritis on scans never matters.' No causal or individual diagnostic conclusion is drawn here.
How do facet injections, medial branch blocks and ablation differ?
The procedure name identifies a target and method, not a promised result. This table describes terminology, not a sequence to follow or an endorsement.
| Procedure | What the name describes | Question for the clinician |
|---|---|---|
| Facet joint injection | Medication placed into the joint with fluoroscopy or CT guidance.[2] | Which joint, side and spinal level are named? |
| Medial branch block | Anesthetic placed near the small nerves associated with the joint.[1] | What question is the block intended to answer? |
| Radiofrequency ablation | An electrode delivers radiofrequency current to selected medial branch nerve fibers.[1] | How does this differ from the proposed injection? |
| Spinal fusion surgery | Surgery that joins vertebrae, described for cases with nerve root compression from enlarged facet joints, degenerative disc disease or spinal instability.[1] | What problem would fusion address that the less invasive options would not? |
Radiofrequency ablation (RFA) is also called facet rhizotomy or, in NICE terms, radiofrequency denervation.[1][5] Mayfield notes that the nerve can regrow through the lesion, and NICE NG59 recommends radiofrequency denervation for chronic low back pain only after a positive response to a diagnostic medial branch block.[1][5]
What happens during a facet joint injection appointment?
RadiologyInfo, the ACR and RSNA patient resource reviewed May 12, 2025, describes an image-guided outpatient procedure, commonly performed by an interventional radiologist.[2] Its account includes local anesthetic and sometimes contrast to confirm placement.[2]
The resource distinguishes the clinician's confirmation that the procedure was completed from the patient's subsequent experience.[2] Ask the treating team how it will record and interpret your response. This page supplies no response threshold, preparation schedule, medication changes or recovery instructions.
Before agreeing to a plan, ask: What diagnosis is being investigated? Which anatomical structure is targeted? What information would change the plan? Who will review the result? Request the proposed procedure's exact written name rather than relying on 'back injection.'
What treatments are used for facet joint syndrome?
Facet joint syndrome is usually managed first with exercise and physical therapy, posture and weight changes, and anti-inflammatory medication, according to Mayfield (2018).[1] Mayfield states that injections and ablation do not change the underlying degeneration.[1]
NICE guideline NG59 tells clinicians not to offer spinal injections for managing low back pain.[5] It supports considering radiofrequency denervation when non-surgical treatment has not worked, the medial branch nerve is the suspected source, and localized pain is rated 5 or more on a visual analogue scale.[5] The low back pain treatment guide and the chronic pain condition page cover the wider options.
Is PRP used for facet joint pain?
Platelet-rich plasma (PRP) facet injections are offered by some regenerative and pain clinics, but published studies are small and none of the clinical sources cited here discusses them.[1][2][5] PRP for spinal pain is generally off label and cash pay. See the PRP therapy treatment guide, how PRP and cortisone injections differ, and the limited evidence for prolotherapy.
Where can you compare PRP Therapy clinic records?
If PRP is already part of a discussion with your clinician, the PRP Therapy clinic directory is a separate listing resource. It is not a facet-joint diagnosis service or a recommendation to substitute PRP for a block, ablation or another treatment.
In Regenerated.com's September 2026 export of 9,042 published clinic records, 2,082 list PRP Therapy across 48 states plus the District of Columbia. This is our directory's recorded coverage, not a count of facet-joint specialists or evidence of treatment outcomes. Source: Regenerated.com directory dataset and methodology.
Compare recorded services through Colorado PRP Therapy clinics, Indiana PRP Therapy clinics or Minnesota PRP Therapy clinics. Individual records include Regenexx Des Moines and Portland Clinic of Holistic Health. Their PRP listing does not establish spine-specific expertise, availability or suitability.

Frequently asked questions
What does lumbar facet joint syndrome mean?
Lumbar facet joint syndrome means pain attributed to the facet joints of the lower back.[1] Lumbar refers to the lower-back region in the studies discussed here, and Kalichman and colleagues assessed CT levels from L2 to S1.[3][4] The phrase names a suspected pain source, not a procedure, and overlaps with facet arthropathy and lumbar facet osteoarthritis.
Does a CT finding mean I need an injection?
A CT finding of facet arthritis does not by itself call for an injection. The 2008 Kalichman and 2013 Suri studies reached different conclusions about scans and pain, and neither evaluated individual injection decisions.[3][4] NICE NG59 also says imaging should not be a prerequisite for radiofrequency denervation.[5] Discuss your own findings with the clinician.
Is a medial branch block the same as radiofrequency ablation?
No. Mayfield describes anesthetic injection near the nerve for a block and an electrode delivering radiofrequency current for ablation.[1] The block is usually a test of whether those nerves carry the pain, and NICE NG59 recommends radiofrequency denervation only after a positive response to a diagnostic medial branch block.[5] These are different methods with different purposes, not interchangeable names.
Who performs image-guided facet joint injections?
RadiologyInfo describes these outpatient procedures as most often performed by an interventional radiologist, using fluoroscopy or CT to guide the needle.[2] Pain medicine specialists, physiatrists and some spine surgeons also perform spinal injections. Ask the proposed provider who will perform yours, what imaging method will be used, and who will review your response afterward.
What does facet joint pain feel like?
Facet joint pain usually feels like a dull, diffuse ache directly over the spine, according to Mayfield Brain & Spine (2018).[1] Low back facet pain can spread to the buttocks and is often worse with bending backward or twisting, and easier when sitting or leaning forward. These patterns overlap with disc and sacroiliac joint problems, so they do not confirm the diagnosis.
Can PRP injections help facet joint syndrome?
Evidence for PRP in facet joint syndrome is limited to small studies, and the Mayfield, RadiologyInfo and NICE sources cited here do not discuss it.[1][2][5] PRP for spinal pain is generally off label and cash pay. If a clinic proposes it, ask which joint and level will be injected, what imaging guidance is used, and what evidence the clinic relies on.
