About this study

The aim of this study is to evaluate the correlation between the fat infiltration of the lumbar multifidus muscle and several parameters including the severity of the lumbar foraminal stenosis. The investigators will analyse lumbar MRI of patients previously included in a database of patients suffering from low back pain. Foraminal stenosis, muscle fat infiltration and other imaging lumbar parameters will be studied by 2D and 3D manuel segmentation, semi-automatic segmentation. Correlations between factors influencing the muscle fat infiltration will be studied by univariate and multivariate statistical analysis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of muscle fat infiltration

    Muscle fat infiltration (%) will be evaluated by 2D segmentation analysis of T2 weighted lumbar spine MRIs

    Measured: 1 year

  2. Percentage of muscle fat infiltration

    Muscle fat infiltration (%) will be evaluated by 3D segmentation analysis of T2 weighted lumbar spine MRIs

    Measured: 1 year

Secondary outcomes (1)
  1. Lumbar foraminal stenosis

    Lumbar foraminal stenosis will be evaluated by 2D segmentation analysis of T2 weighted lumbar spine MRIs and expressed as a nerve/foramen surface ratio, and by the Lee et al. Classification

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Low Back Pain and Degenerative Condition, Neurologic, run by Centre Hospitalier Universitaire de Nice at 1 site in France.

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

Who may be eligible to take part?

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 5 Mar 2025. 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 France. 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?

Percentage of muscle fat infiltration (time frame: 1 year). The study lists 2 primary outcomes in all. 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 5 Mar 2025.
