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 Results may not be published yet.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

Summary

This study tests a minimally invasive procedure to release a trapped median nerve at the elbow (lacertus syndrome) using ultrasound guidance. Instead of a large cut, doctors make a tiny incision and cut the tight band pressing on the nerve. The goal is to reduce pain, improve hand strength, and allow patients to return to work within a week. The trial will enroll 107 adults with confirmed lacertus syndrome and normal nerve tests.

What this could mean

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

Active substance
Ultrasound-guided percutaneous release of the lacertus fibrosus
What this could lead to
If successful, this could offer a safer, faster-recovery alternative to open surgery for lacertus syndrome, with less scarring and quicker return to daily activities.
What could go wrong
This is a relatively small, early-stage study (107 participants) with no comparison group, so results may not apply broadly. Risks include bruising, incomplete relief, or rare nerve damage.

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.

About 107 people

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