Radiofrequency Ablation for Back Pain: Does It Help?

What does recent research show about radiofrequency ablation?

A systematic review published in BMJ Open in July 2026 examined 55 randomized trials involving 4,394 participants. It covered radiofrequency treatments for several sources of chronic low back pain, including facet joints, sacroiliac joints and discs. The authors reported small improvements in pain and function, but judged the effects below their predefined thresholds for clinical importance. These totals cover different procedures and diagnoses, rather than one uniform treatment. [BMJ Open review](https://bmjopen.bmj.com/content/16/7/e105106)

The evidence ranged from very low to moderate certainty. Small studies and differences in patient selection and treatment technique limited confidence. The findings leave uncertainty about which patients might benefit enough to justify treatment. The authors called for larger, more rigorous trials and longer follow-up.

Who might be considered for radiofrequency ablation?

For suspected facet joint pain, radiofrequency denervation uses heat to interrupt signaling through small nerves supplying joints at the back of the spine. A clinician places a needle near the target nerve and delivers radiofrequency energy. The procedure changes nerve signaling without repairing the joint itself. Nerves can regenerate, allowing pain to return. Facet nerve treatment is also distinct from procedures targeting discs or other spinal structures.

NICE recommends considering referral when nonsurgical treatment has failed, localized back pain is moderate or severe, and the suspected source is supplied by medial branch nerves. Its guidance requires a positive response to a diagnostic medial branch block before denervation. This injection temporarily numbs the relevant nerves to help assess whether they contribute to the pain. [NICE recommendations](https://www.nice.org.uk/guidance/ng59/chapter/Recommendations)

Why do guidelines disagree about back pain ablation?

A clinical practice guideline published in The BMJ in February 2025 issued a strong recommendation against joint radiofrequency ablation for chronic axial spine pain, meaning pain centered around the spine. Its scope excluded pain associated with cancer or inflammatory arthropathy. The panel weighed uncertain benefits against complications, repeated procedures and treatment burdens. Its recommendation differs from NICE's selective pathway, making the applicable diagnosis and guideline important parts of a treatment discussion.

Patients should also understand the range of possible outcomes. Mayo Clinic describes conflicting evidence: some people experience temporary relief, while others gain no improvement in pain or function. Temporary soreness and numbness can occur; uncommon serious complications include bleeding, infection and nerve injury. A consultation should address these possibilities alongside the expected benefit.

Regardless of whether a procedure is considered, NICE recommends support for remaining active and exercise adapted to the person's needs. For persistent pain, combined physical and psychological approaches may also be appropriate. A treatment plan should specify practical goals, such as easier walking or improved daily activity, and how progress will be assessed.
