Trial summary

Pulsed radiofrequency applied to the dorsal root ganglion (DRG) is an interventional treatment alternative in the treatment of lumbar radicular pain that does not respond to conservative methods. Under intermittent fluoroscopic imaging, the location of the ganglion can be determined by administering contrast media. Read more about this study

About this study

Official title: The Role of Radiocontrast Media in Pulsed Radiofrequency Treatment of Lumbar Dorsal Root Ganglion

Pulsed radiofrequency applied to the dorsal root ganglion (DRG) is an interventional treatment alternative in the treatment of lumbar radicular pain that does not respond to conservative methods. Under intermittent fluoroscopic imaging, the location of the ganglion can be determined by administering contrast media. We consider that determining the localization of the ganglion with this method during pulse radiofrequency application can shorten the procedure time. In this way, we believe that it would help the correct application of the procedure.

Read the detailed description

Although there are many reasons that can lead to low back pain, radicular pain, which is mostly secondary to lumbar disc hernia, is one of the most common pathologies. Pulsed radiofrequency applied to the dorsal root ganglion (DRG) is an interventional treatment alternative in the treatment of lumbar radicular pain that does not respond to conservative methods and epidural injection treatments.

The electrical field created by the application of pulsed radiofrequency (PRF) changes the cellular activity in DRG neurons. By polarizing cell membranes, reduces nociceptive transmission and contributes to analgesia. In lumbar dorsal root ganglion PRF applications, when the targeted point is reached, the position is confirmed by giving motor and sensory stimuli, and the PRF application is initiated in the follow-up. However, it is a problem that the DRG is not always in the same location, and therefore, time is often lost or even not found while searching with stimulation. Under intermittent fluoroscopic imaging, the location of the ganglion can be determined by administering contrast material.

We consider that determining the localization of the ganglion with this method during pulse radiofrequency application can shorten the procedure time. In this way, we believe that it would help the correct application of the procedure.

Study groups in NCT04876469
Study groupRoleWhat they receive
Radiocontrast media groupActive comparatorPulsed radiofrequency (PRF) treatment will be applied to the dorsal root ganglion (DRG) by fluoroscopy-guidance at the level of nerve root compression due to disc herniation (L5 level) in both groups. In patients in the Radiocontrast media group, contrast material will be given before the application, and primarily the localization of the DRG will be determined. After this stage, the needle will be directed towards the detected localization. Finally, the localization of the dorsal root ganglion will be confirmed by sensory and motor stimuli.
Receives: Procedure: Pulsed Radiofrequency treatment of the lumbar dorsal root ganglion
Non-radiocontrast media groupActive comparatorPulsed radiofrequency (PRF) treatment will be applied to the dorsal root ganglion (DRG) by fluoroscopy-guidance at the level of nerve root compression due to disc herniation (L5 level). In patients in the Non-radiocontrast media group, the localization of the dorsal root ganglion will be determined just by sensory and motor stimuli.

Questions about this trial

What is this clinical trial studying?

A study testing Pulsed Radiofrequency treatment of the lumbar dorsal root ganglion in people with Lumbar Radiculopathy and Pain, Intractable, run by Sanliurfa Education and Research Hospital at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 6 May 2021. 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 Turkey (Türkiye). 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Procedure time (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04876469, which also lists 4 linked publications.

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 6 May 2021.
