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 Results may not be published yet.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.

Summary

This study compares two types of wrist fusion surgery for people with advanced wrist arthritis (SNAC or SLAC). The simpler procedure, lunate-capitate fusion (LCF), is being tested against the standard four-corner fusion (4CF) to see if it provides similar grip strength and function. About 64 adults with grade 2-3 arthritis will be randomly assigned to one surgery and followed for outcomes like strength, motion, and quality of life.

What this could mean

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

Active substance
surgery (lunate-capitate fusion or four-corner fusion)
What this could lead to
If successful, this could show that a simpler, less invasive wrist fusion surgery works as well as the standard procedure, offering patients a faster recovery with similar outcomes.
What could go wrong
This is a small, early-stage trial with only 64 participants, so results may not apply to everyone. Both surgeries carry risks like infection or the bone not healing properly.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
