What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers compare two ways to numb the arm for realigning a broken wrist without surgery. Adults with a distal radius fracture receive either an ultrasound-guided brachial plexus nerve block or a haematoma block, the standard method in Danish emergency departments. The trial measures how many participants later need wrist surgery and tracks complications from each approach.

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 brachial plexus nerve block
What this could lead to
If the nerve block works better, it could become the preferred way to numb the arm for realigning wrist fractures, potentially reducing the need for later surgery.
What could go wrong
Nerve blocks can cause nerve irritation or bleeding, and the trial may find no difference between the two methods. Results may not apply outside Denmark.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults (age ≥ 18 years) with a distal radius fracture in need of closed reduction Exclusion Criteria: * Patients who would never qualify for surgery according to local guidelines * Lack of informed consent * No Danish Central Person Register (CPR) number * Allergies to the trial medication * Distal radius fracture initially deemed to require surgery regardless of the outcome of the closed reduction * Open fractures (fracture-related wound requiring sutures) * Other fractures on the same extremity ((NOT including distal ulna fracture(s)) * Bilateral distal radius fractures both requiring closed reduction * Concomitant medical or surgical condition taking priority over the closed reduction of the distal radius fracture.
