Cryoneurolysis vs Radiofrequency Ablation for Chronic Sacroiliac Joint Pain

"The iovera° system consists of a reusable, portable Handpiece, along with single-patient use sterile Smart Tips (i.e., cryoprobes) and disposable nitrous oxide (N2O) cartridges. The iovera° system produces the desired effect through initiation of a cooling cycle. Each cooling cycle is initiated by fully inserting the Smart Tip into the selected procedure site and activating the cryogen flow. The Smart Tip needles are made of stainless steel and have a closed tip, fully enclosing the cryogen. The STT21180STIM Smart Tip will be used in this study."

Radiofrequency ablation is a minimally invasive procedure that uses heat at the lumbosacral spine to destroy the target spinal nerves.
