Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This study compared two heat-based procedures to treat pain from the sacroiliac joint, a common cause of low back pain. One method uses a newer device to create larger burns, while the other uses a standard technique. The trial enrolled 20 adults with long-term pain who had not improved with other treatments. The goal was to see which approach provides better pain relief and function over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
radiofrequency ablation (a procedure using heat to block pain nerves)
What this could lead to
If successful, this could show that a newer, more extensive ablation technique provides longer-lasting pain relief for people with sacroiliac joint pain.
What could go wrong
This was a small, early-phase trial that was terminated, so results are limited. The procedure carries risks like infection, nerve damage, or temporary increased pain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult participants aged 18-90 years old with at least 3 months of low back pain who have not responded to at least 3 months of conservative treatment. * 7-day average NPRS for low back pain of at least 4/10 at baseline * Pain relieved by at least 50% by either a fluoroscopically-guided intraarticular sacroiliac joint injection including a local anesthetic and a fluoroscopically-guided PSN block or dual fluoroscopically-guided PSN blocks. * Participants capable of understanding and providing consent in English and capable of complying with the outcome instruments used. A pain diary with appropriate diagnostic categories of relief (100% relief, 80-99% relief, etc.), will be provided. Duration of pain relief will not be used as it has been shown to only marginally improve diagnostic confidence (17). Exclusion Criteria: * History of SIJ fusion. * Prior SIJ RFA procedure * Symptomatic hip osteoarthritis * Active lumbar radicular pain * Evidence of hardware loosening (in participants with history lumbar or lumbosacral fusion). * Presence of pacemaker or neurostimulator. * Chronic widespread pain or somatoform disorder (e.g., fibromyalgia). * More than 50 mg morphine-equivalent per day opioid use. * Active bacterial infection or treatment of infection with antibiotics within the past 4 weeks. * Medical conditions causing significant functional disability (e.g., stroke, COPD). * Addictive behavior, severe clinical depression, or psychotic features. * History of anaphylactic reaction to any medication used. * Those receiving remuneration for their pain treatment (e.g., disability, worker's compensation). * Those involved in active litigation relevant to their pain. * The participant is incarcerated.
