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 This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

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 Results may not be published yet.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.

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.

Summary

This study compares a minimally invasive ultrasound-guided injection to standard open surgery for carpal tunnel syndrome. 72 adults who have not improved with conservative treatments will be randomly assigned to receive either the injection or surgery. The main goal is to see if the injection is as good as surgery at relieving symptoms after 3 months, with potential benefits like faster recovery.

What this could mean

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

Active substance
saline and dextrose solution with local anesthetic and betamethasone
What this could lead to
If it works, this could offer a less invasive alternative to surgery for carpal tunnel syndrome, with faster recovery and fewer complications.
What could go wrong
This is a small early-stage trial with only 72 participants, and the injection may not be as effective as surgery in the long run. There is also a risk of nerve damage or infection from the injection.
