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
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 This study
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 Results may not be published yet.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.

Summary

This trial compares two types of ultrasound-guided nerve blocks—pericapsular nerve group (PENG) and fascia iliaca compartment block (FICB)—for pain relief after total hip replacement surgery. Adults aged 18 to 80 scheduled for hip replacement under spinal anesthesia will be randomly assigned to receive one of the two blocks. Researchers will measure pain levels over 24 hours, the amount of rescue pain medication needed, and how quickly patients can walk again. The goal is to see which block provides better pain control and faster recovery.

What this could mean

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

Active substance
Two types of ultrasound-guided nerve blocks: pericapsular nerve group (PENG) block and fascia iliaca compartment block (FICB)
What this could lead to
If one block proves better, it could lead to improved pain control and faster recovery for people undergoing hip replacement surgery.
What could go wrong
This is a small, early-stage comparison, and results may not apply to all patients. Nerve blocks carry risks like bleeding, infection, or nerve damage, though rare.
