What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a special MRI technique, called diffusion MRI with tractography, can clearly map the nerves of the brachial plexus—the network that controls arm movement—in people who had a birth-related injury to these nerves. The goal is to see if this imaging can reveal the exact location and extent of nerve damage compared to the healthy side. If it works, it could lead to a better, non-invasive way to diagnose and manage these injuries.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Advanced diffusion MRI and tractography imaging technique
What this could lead to
If successful, this imaging technique could provide a non-invasive way to pinpoint nerve damage in brachial plexus injuries, potentially guiding better treatment decisions.
What could go wrong
This is a very small feasibility study, so the technique may not prove reliable or generalizable. It is exploratory and does not yet offer a proven diagnostic tool.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 8 people

The number the study aims to enrol. It can still change while the study runs.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Inclusion Criteria: * Patients aged 14 to 30 years * Consulted by the Orthopedics Department at Armand Trousseau Hospital * Diagnosed and monitored by Armand Trousseau Hospital for obstetrical brachial plexus palsy (OBBP) * Having a single, unoperated lesion (lesions are very different and only exceptionally affect all the roots bilaterally). * Not suffering from bone or neurological pathology unrelated to OBP * Patients affiliated with or entitled to a social security scheme * Patients who have received informed information and have signed, with the investigator, a consent form to participate in the study * Parents/legal guardians who have received informed information and have co-signed, with the investigator, a consent form to participate in the study, for minor patients Exclusion Criteria: * History of rheumatoid pathologies, constitutional bone diseases, past or current pathologies affecting the arm or neck unrelated to the obstetric brachial plexus, any history of neoplasia or radiographic appearance consistent with a neoplastic fracture * Current pregnancy * Inability to perform the MRI examination (presence of a contraindication, incapacitating pain, or claustrophobia) * Large tattoo present in the area of interest (artifacts) * Patients deprived of liberty, or under guardianship/curatorship * Patients receiving medical assistance (AME)
