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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Carpal tunnel syndrome happens when a nerve in the wrist gets squeezed, causing pain, numbness, and weakness in the hand. Open surgery has long been the standard fix, but a newer minimally invasive method uses ultrasound to guide the release through a much smaller opening. This study follows 200 adults who need surgery, comparing how much their symptoms and hand function improve over a year. Researchers track pain, grip, and quality of life to see whether the ultrasound-guided approach holds up against traditional open surgery.

What this could mean

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

Active substance
Two surgical approaches for carpal tunnel syndrome: traditional open release and minimally invasive ultrasound-guided release
What this could lead to
If the ultrasound-guided approach works as well as open surgery, it could offer people with carpal tunnel syndrome less postoperative pain and a faster return to normal hand use.
What could go wrong
This is an observational study, not a randomized trial, so differences between the two groups may reflect patient or center characteristics rather than the procedures themselves. The minimally invasive technique also requires specific ultrasound skills, and results may not apply everywhere.

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

Inclusion Criteria: * Electrophysiologically verified Carpal Tunnel Syndrome by EMG/nerve conduction studies, with the examination not older than 6 months at the time of inclusion. * Previous documented and exhausted conservative treatment * Existing indication for surgery that has been discussed with the patient and the patient's explicit wish to undergo surgical treatment. * Ability to provide informed consent and written informed consent * Age ≥18 years. Exclusion Criteria: * Previous surgery at the affected location or revision procedures. * Pre-existing nerve lesions of the upper extremity, including traumatic transections or proximal injuries. * Manifest polyneuropathy. * Foreseeable loss to follow-up, for example inability to contact the participant or insufficient compliance, before the critical 3-month follow-up. * Age under 18 years.
