A guide to cervical and lumbar facet-related pain, diagnostic uncertainty, CT-guided treatment and PRP evidence.
Key message: Facet degeneration is common on scans and does not automatically mean the facet joint is causing pain. The strongest pathway combines advanced imaging with clinical pattern and, when needed, diagnostic blocks.
What are facet joints?
Facet joints are small paired joints at the back of the spine. They can develop osteoarthritis, capsular irritation and mechanical pain. Lumbar facet pain may be felt across the low back and buttocks; cervical facet pain may contribute to neck pain and some headache patterns.
Why scans alone are not enough
Facet arthritis is common in people with no pain. MRI and CT can show degeneration, inflammation and other spinal pathology, but the image must be interpreted with symptoms and examination. A diagnostic medial branch or intra-articular local-anaesthetic block may sometimes be used to test the suspected pain source.
Can PRP help facet pain?
Facet-joint PRP evidence is developing but not settled and like most PRP data not based on a standardised PRP composition and dose. The 2026 facet/SIJ meta-analysis found better pooled pain outcomes with PRP at 3 and 6 months, yet a separate 2026 double-blind randomised lumbar facet trial found PRP was not superior to corticosteroid for its primary 6-month pain outcome. A systematic review of regenerative treatments for facet-origin axial pain graded PRP evidence as moderate/Level II overall, with low certainty. This is exactly why a facet procedure should follow a careful diagnostic pathway rather than being offered simply because degeneration is visible on imaging. [18-20]
Why CT guidance may be selected
Facet joints are small and deep. CT provides high-confidence bony localisation and can be useful when millimetres matter, particularly in the spine. The procedural record can document the side, level and final needle position.
What should I expect after?
Temporary local soreness is common. The injected joint may take days to weeks before any benefit becomes clear. Rehabilitation, posture, strength and treatment of other pain generators remain important.
What if the procedure does not help?
A technically accurate injection that does not improve symptoms is still clinically informative. It may indicate that the facet was not the main driver, that several pain generators are present, or that the biologic treatment did not produce the desired response.
Frequently Asked Questions
Is facet arthritis the same as facet pain?
No. Arthritis is common and may not cause pain. MRI with contrast is required to show inflammation of facet joints as synovitis.
Is PRP used in the neck as well as the lower back?
Selected cervical targets may be considered, but the anatomy is more complex and therefore fewer providers perform this injection regularly. Treatment should be individualised.
Why save an image of needle position?
A final procedural image improves traceability by documenting which level and structure were treated. It does not prove that the treatment will work.
Important: Progressive weakness, bowel or bladder dysfunction, fever, severe trauma or other neurological red flags require urgent assessment rather than elective facet treatment.
