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 Results may not be published yet.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.

Summary

Researchers are studying a surgical procedure called anterior aesthetic rib cage remodeling with osteosynthesis (ARCO) in adults aged 18 to 45 with a prominent or misshapen lower rib cage. Through small incisions under the breast, surgeons cut the outer layer of ribs 6, 7, and 8, reshape them, and hold them in place with titanium plates and screws. The study tracks rib cage circumference, CT scans, breathing tests, chest appearance scores, and complications for 12 months to see whether the procedure reduces the lower rib bulge and how safe it is.

What this could mean

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

Active substance
a surgical procedure that reshapes and stabilizes the lower ribs with titanium plates
What this could lead to
If it works, this could offer adults with a prominent lower rib cage a surgical option to reduce the bulge and improve chest appearance.
What could go wrong
This is a single-group study with no comparison group, so any improvement cannot be clearly attributed to the surgery. Rib surgery carries risks such as collapsed lung, bleeding, infection, and problems with the plates or bone healing.
