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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study is testing whether a special bone scan (SPECT/CT) can predict which patients with chronic back pain will have good results from lumbar fusion surgery. Researchers will measure how much the scan lights up in the spine and compare it to pain and disability scores one year after surgery. The goal is to better select patients for surgery and avoid operations that won't help.

What this could mean

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

Active substance
bone scan (SPECT/CT with SUVmax measurement)
What this could lead to
If successful, this could help doctors identify which patients are most likely to benefit from lumbar fusion surgery, reducing unnecessary procedures.
What could go wrong
This is a small, early-stage study with only 70 participants, and the scan may not reliably predict outcomes. Results may not apply to all back pain patients.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants
