Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It might be best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment Cryoneurolysis for low back pain?

Research shows that cryoneurolysis has been reported to induce favorable outcomes in lumbar facet joint pain, which is a common cause of low back pain. Clinical studies have reported promising results, focusing on improvements in pain scores and patient satisfaction.12345

How does cryoneurolysis differ from other treatments for low back pain?

Cryoneurolysis is unique because it uses extreme cold to temporarily disable nerves that cause pain, offering an alternative to traditional methods like radiofrequency ablation, which uses heat. This approach can be effective for chronic pain conditions and may provide temporary relief, allowing for repeated treatments if successful.23678

What is the purpose of this trial?

Low back pain (LBP) is the leading cause of disability worldwide. Currently available treatment options for treating low back facet joint pain include acupuncture, pain medications, psychotherapy, anti-inflammatory steroid injections into the joints, exercise, physical therapy, rest, chiropractic treatments, surgery, and radiofrequency ablation (RFA). RFA uses radio waves to target and burn the nerves that send the pain signals to the participant's brain. The purpose of this study is to compare the standard treatment of RFA to a newer therapy called iovera°. The iovera° system is a newer procedure for nerve pain that freezes the targeted nerves leading to a temporary block of the nerve without causing any permanent damage to the nerve. With the nerve blocked, pain is immediately relieved. The nerve reconnects over time and goes back to working exactly as it did before the procedure. The investigators want to see if iovera° therapy is effective in treating people with facet joint-mediated chronic low back pain (CLBP).If the participant decide to participate in the study, the investigators will ask the participant to undergo either an RFA or iovera° procedure to treat the participant's CLBP. After the procedure, the investigators will ask the participant to complete surveys to track the participant's response to the procedure at 15 time points over a 1-year period. These time points consist of phone calls and online surveys.

Treatment Details

Interventions

  • Cryoneurolysis
  • Radiofrequency Ablation
Trial Overview The study compares two procedures: RFA, which uses radio waves to burn nerves transmitting pain signals, and the iovera° system, which temporarily freezes these nerves without causing permanent damage. The effectiveness of both in treating chronic low back pain is being evaluated.
Participant Groups
2Treatment groups
Active Control
Group I: iovera systemActive Control1 Intervention
Uses liquid nitrous oxide contained within the device and a closed-end needle to create a precise zone of cold to denature the target medial branch nerve supplying the facet joint by Wallerian degeneration (second degree axonotmesis) preserving the epineurium, perineurium, and endoneurium.
Group II: Radiofrequency ablationActive Control1 Intervention
Utilizes radiofrequency energy to heat and denature the target medial branch nerve supplying the facet joint.
