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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares a new traction method that avoids using a perineal post during hip arthroscopy to the standard method. The goal is to see if it reduces nerve injuries, pain, and other complications. 270 people with femoroacetabular impingement syndrome will be randomly assigned to one of the two traction techniques.

What this could mean

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

Active substance
Perineal Post-Free Traction (procedure)
What this could lead to
If successful, this could offer a safer traction method for hip arthroscopy, reducing nerve injuries and improving recovery.
What could go wrong
This is an early-stage trial with 270 participants, so results may not apply to all patients. The new technique might not reduce complications or could have unforeseen issues.

Participants

About 270 people

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