About this study
Official title: Cervicale Facet Joint Denervation With a Trident Electrode, a Retrospective Observational Study
This observational retrospective study evaluates the efficacy of RF with the three-tined expandable electrode needle compared to before treatment in the treatment of chronic cervical facet joint pain.
- Conditions
- Facet Joint Pain
- Being tested
- Radiofrequency denervation of the cervical facet joint
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Radiofrequency denervation of the cervical facet jointProcedure or surgery
Radiofrequency denervation of the medial branch of the dorsal ramus of the cervical facet joint with a three-tined expandable needle.
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain measurement by numeric rating score
The primary outcome of this study is pain measured with the numeric rating score (NRS): 11-point NRS ranging from 0 (no pain at all) to 10 (the worst imaginable pain). A score of zero (0) will indicate that the patient is pain free, while a score of ten (10) will indicate that they are experiencing the worst pain imaginable.
Measured: 2 months after injection in comparison to baseline
Secondary outcomes (5)
Patient Global Impression of Change (PGIC)
The PGIC rating is increasingly being used for determining clinically important change in measures such as ratings of pain. This scale is designed to quantify patient's improvement or deterioration over time, usually either to determine the effect of an intervention or to chart the clinical course of a condition. The scales ask that a person assess his or her current pain, recall that status at a previous time-point, and then calculate the difference between the two.
- very much improved
- much improved
- minimally improved
- no change
- minimally worse
- much worse
- very much worse
Measured: 2 months after injection
Use of analgesics
The quantity of analgesics that the patient assumes for the pain:
- All stopped
- Decreased
- Equal
- Increased
Measured: 2 months after injection
Sleep
Question: 'your sleep quality is:
- Improved
- Equal
- Worsened'
Measured: 2 months after injection
Walking ability
Question: 'after the treatment, you can walk:
- More than before
- Same as before
- Less than before'
Measured: 2 months after injection
Patient satisfaction
Question: are you satisfied with the result: YES/NO
Measured: 2 months after injection

Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain measurement by numeric rating score (time frame: 2 months after injection in comparison to baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2023; AzTrials last refreshed its copy on 27 Oct 2026.
