About this study

Official title: Evaluación de la Analgesia a Corto y Medio Plazo de Las Diferentes Posiciones y Tipos de Las cánulas de Radiofrecuencia, en la denervación Del Ramo Medial Del Nervio Dorsal Lumbar

Prospective study to analyse pain reduction with two types of canulae and two types of placements for lumbar medial branch radiofrequency denervation.

Read the detailed description

Patients who suffer from lumbar zygapophyseal joint pain often receive radiofrequency medial branch denervation as treatment. Many types if canulae exist, and many types of placing them in relation to the Medial Branch nerves (MB). The EARL study tries to compare the analgesic effect of thin canulae (22 gauge) placed perpendicular to MB to thicker canulae (18 gauge) placed parallel to MB.

Questions about this trial

What is this clinical trial studying?

A study testing PAIN REDUCTION ON VAS/NRS in people with Lumbar Facet Joint Pain and Lumbar Medial Branch Neurotomy, run by Instituto de Investigación Hospital Universitario La Paz at 1 site in Spain.

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 7 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 18 Jan 2020. 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 Spain. 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 REDUCTION ON VAS/NRS (time frame: 1-3-6 months). 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 18 Jan 2020.
