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 Results may not be published yet.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

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 tests a portable ultrasound system to measure the position of the shoulder blade (scapula) in patients with shoulder arthritis while they stand. The goal is to see if this non-radiation method can give results similar to CT scans taken when lying down. Thirty adults scheduled for shoulder replacement surgery will participate, and the researchers will compare the measurements from both positions.

What this could mean

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

What this could lead to
If accurate, this portable ultrasound method could replace CT scans for assessing shoulder joint positioning, reducing radiation exposure.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply to all patients. The device's accuracy is still being validated.
