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 Results may not be published yet.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 trial asks whether adding morphine to spinal anesthesia or using an ultrasound-guided nerve block provides better pain control after hip surgery. Sixty-four adults having hip replacement or hip fracture surgery will be randomly assigned to one of the two methods. Researchers will compare pain scores, total morphine use, and side effects during the first 48 hours after surgery to see which approach reduces opioid needs and improves recovery.

What this could mean

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

Active substance
Morphine added to spinal anesthesia or an ultrasound-guided pericapsular nerve group (PENG) block
What this could lead to
If one method works better, it could point to a way to ease pain after hip surgery while reducing opioid use and side effects.
What could go wrong
This is a small, early-stage comparison, so results may not apply to everyone. Both methods carry risks like nausea, breathing problems, or nerve block complications.
