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 Results may not be published yet.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

Summary

This study compares two types of nerve blocks—PENG block and lumbar erector spinae plane block—to see which one better controls pain after total hip replacement. Fifty-two adults undergoing hip replacement under spinal anesthesia will be randomly assigned to receive one of the two blocks. Researchers will measure pain scores, opioid use, and patient satisfaction over 24 hours 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
nerve block (PENG block or lumbar erector spinae plane block)
What this could lead to
If it works, this could show which nerve block provides better pain relief after hip replacement, potentially reducing opioid use and improving recovery.
What could go wrong
This is a small, early-stage trial with only 52 participants, so results may not apply to everyone. Both blocks are already known to work; the study only compares them, so no major breakthrough is expected.
