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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This observational study looks at whether the size of two lower-back muscles, the psoas and multifidus, measured on MRI scans taken before surgery, is related to how well patients recover after surgery for a herniated disc. The study will include 100 adults aged 18 to 75 scheduled for elective disc surgery. Participants will receive standard care and complete a recovery questionnaire before surgery and at several points afterward. The goal is to see if these muscle measurements are linked to better or worse recovery, which could help personalize care in the future.

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 a link is found, doctors might use routine MRI scans to predict recovery and tailor post-surgery care, potentially improving outcomes for patients undergoing disc surgery.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The findings may be influenced by other factors, and the results might not apply to all patients or surgical approaches.

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 a consecutive sample of adult patients aged 18 to 75 years with ASA physical status I-III who are scheduled for elective surgery for lumbar disc herniation under general anesthesia at Fatih Sultan Mehmet Training and Research Hospital. Eligible participants must have an existing preoperative lumbar MRI suitable for psoas and multifidus muscle measurements and must be able to complete the Turkish version of the QoR-15 questionnaire.
