RFA Using Multi-Tined Electrodes vs.Traditional Electrodes for Lumbar Spondylosis
NCT06477094 · View on ClinicalTrials.gov ↗
Study Summary
Spondylosis is an anatomical defect of the small facet joints between the spinal vertebrae often due to load bearing and mechanical wear. It is a major contributor to lower back pain. The current standard of care in patients diagnosed with spondylosis in the lower back is to perform a radiofrequency ablation (RFA) of the lumbar medial branch nerves which carry the pain signals from that region to the brain. RFA accomplishes this by using radio waves transmitted through inserted electrodes. This leads to a temporary lesion or "burn"; stopping the pain signals from being transmitted as as well as changing the pain signals themselves. The electrodes themselves do not heat up but instead cause ions in the surrounding tissue to vibrate and heat up. When performing the procedure at the UAMS pain clinic, one can use the Stryker system with a single electrode end which protrudes out of the cannula or the Stratus Nimbus electrode with two prongs which expand in a "V"; formation along the sides of the cannula. While testing in chicken tissue shows that the latter electrode type produces a larger lesion size, anecdotal evidence suggests that it may lead to longer term pain relief. As such, the choice is currently left up to physician preference as both are FDA approved for use in this condition. This study is trying to assess if the larger lesion size results in a reduction in impairment of activities of daily living due to pain measured by the patient-reported PROMIS (Patient Reported Measurement Information System)-29 questionnaire. The PROMIS-29 is given to all patients who are seen in the UAMS Pain Clinic at initial and follow-up visits. In this study we would like to randomize what electrode and cannula set is used in RFA for patient's who are already going to be receiving the procedure for treatment for their spondylosis. The study team would then compare the PROMIS outcomes between cases that used the Stryker and Stratus Nimbus electrodes at 1,3,6,9 and 12 months. It is

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06477094
The ClinicalTrials.gov registry entry for NCT06477094 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 25 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Arkansas, which has 194 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Lumbar Spondylosis appearing as the primary indexed condition, and to 2 interventions — of which Stratus Nimbus Electrosurgical RF Multi-Tined Expandable Electrode is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06477094 reports 1 study location spanning 1 distinct geographic area — top geographies include Arkansas. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
