Lumbar medial branch radiofrequency ablation is an effective and durable intervention for z-joint lower back pain.
Why this matters ?
Lumbar medial branch radiofrequency ablation (RFA) is increasingly used to treat lower back pain at the lumbar zygapophyseal joint (z-joint); the procedure is associated with significant pain relief and functional improvement.
However, when diagnosis or procedural techniques are suboptimal, outcomes are disappointing. Clear diagnostic thresholds and improved procedures will ensure that patients most likely to benefit from treatment will be identified.
