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 Results may not be published yet.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

Summary

This study checks how consistently six doctors can grade degeneration of the small joints in the spine (facet joints) using CT scans. It includes 12 patients and uses the Pathria scale. The goal is to see if the grading method is reliable, not to test a treatment.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of patients aged 18 to 50 years with AOSpine type A2, A3, or A4 thoracolumbar fractures whose previously acquired CT examinations are available in the institutional imaging archive. Eligible CT datasets must cover vertebral levels T9 through L3 and be suitable for standardized facet joint assessment. The study will use anonymized retrospective imaging data only; there will be no direct patient recruitment, additional imaging, treatment allocation, or other study-specific intervention. CT datasets will be selected according to predefined eligibility criteria until at least 142 evaluable facet joints are available for analysis.

Ages
