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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

People with ankylosing spondylitis have stiff, fused spines that break easily, and surgeons often struggle to line up the broken bones before stabilizing them with screws and rods. This study reviews the records of 23 adults who had a specific type of thoracolumbar fracture and were treated with an inflatable positioning device during surgery. Researchers look at complication rates and hardware problems to see whether the technique is safe and practical.

What this could mean

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

Active substance
an inflatable positioning device used during surgery to help align broken spinal bones
What this could lead to
If the approach proves reliable, it could offer surgeons a gentler way to line up spinal fractures in people with stiff, fused spines before they place screws and rods.
What could go wrong
This is a small retrospective review of past cases at one hospital, so it cannot prove the device works better than standard positioning. Complications such as screw loosening or infection can still occur with any spinal surgery.
