Double nerve block may ease hip surgery pain
NCT ID NCT07263932
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two nerve block methods for pain after total hip replacement. One group gets a standard front-hip block, the other gets that plus a back-hip block. Researchers will measure pain scores, recovery quality, and how quickly patients can move after surgery. The goal is to see if the combo block provides better pain relief 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
- bupivacaine
- What this could lead to
- If it works, this could lead to better pain control and faster recovery after hip replacement surgery.
- What could go wrong
- This is a small, early-stage study comparing two nerve block techniques. The results may not apply to all patients, and there is a risk of block-related complications like nerve injury or infection.

Who is studied
Adult patients aged 18 years and older, classified as ASA physical status I-II, scheduled for elective total hip arthroplasty under spinal anesthesia at Ankara Bilkent City Hospital. A total of 132 patients who meet the inclusion criteria and provide written informed consent will be enrolled in this single-center, prospective, randomized controlled trial.
