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 Results may not be published yet.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.

Summary

This study tests whether a specific injection technique called erector spinae plane block (ESPB) reduces pain and opioid use after lumbar spinal fusion better than standard subcutaneous anesthesia. Researchers will enroll 66 adults scheduled for one- or two-level lumbar fusion. Participants will receive either ESPB or subcutaneous anesthesia, and their pain, disability, and opioid use will be tracked for two weeks after surgery.

What this could mean

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

Active substance
local anesthesia (injected via erector spinae plane block or subcutaneously)
What this could lead to
If it works, this could point toward a better way to manage pain after spinal fusion surgery, potentially reducing reliance on opioids.
What could go wrong
This is a small, early-stage study with only 66 participants, so results may not apply to everyone. The difference between the two methods might be small or not clinically meaningful.
