New hip block could let patients move sooner after surgery
NCT ID NCT07239817
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares a new local anesthesia technique called PENG 360° to standard spinal anesthesia for people having hip replacement surgery after a fracture. The goal is to see if the new method controls pain just as well while allowing patients to move their leg sooner. One hundred adults will be randomly assigned to receive either the new block or spinal anesthesia, and researchers will track pain medicine use and leg movement for two days 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
- Ropivacaine and mepivacaine with epinephrine (local anesthetic mixture)
- What this could lead to
- If it works, this could offer a safer, motor-sparing pain control option for hip surgery patients, potentially reducing nausea and allowing faster recovery of leg movement.
- What could go wrong
- This is a small, early-phase trial with only 100 participants, so results may not apply to everyone. The new technique might not control pain as well as spinal anesthesia, and there is a risk of allergic reaction or infection at the injection site.
