NCT ID NCT04650100
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding a special nerve block (called PENG block) to standard pain injections could better control pain after hip replacement surgery. 64 adults scheduled for hip replacement took part. The goal was to see if the nerve block reduces the need for morphine and preserves leg muscle strength.
