To investigate the safety and feasibility of a fluoroscopy-guided, high-intensity focused ultrasound system for zygapophyseal joint denervation as a treatment for chronic low back pain. ⋯ The first clinical pilot study using a noninvasive, fluoroscopy-guided, high-intensity focused ultrasound lumbar zygapophyseal neurotomy resulted in no significant device- or procedure-related adverse events and achieved clinical success comparable with that of routine radiofrequency ablation.

Observational Study
The Immediate Adverse Events of Lumbar Interventional Pain Procedures in 4209 Patients; an Observational Clinical Study.
Lumbar interventional pain procedures (LIPPs) are frequently used in low back pain and have shown an increasing trend in recent years. LIPPs are highly effective when performed by properly trained physicians. However, some adverse events are seen during interventional procedures. Our aim in this study is to determine the immediate adverse event rates of LIPPs and to inform our colleagues about possible adverse events. ⋯ No major adverse events were seen in 4,209 patients. The rate of minor adverse events was 1.4%, with no sequelae in any of the events. When evidence-based guidelines are followed, interventional pain procedures can be performed safely.
