Summary

This study tests whether a quadratus lumborum (QL) nerve block can reduce pain and the need for opioid painkillers after hip replacement surgery. 80 adults having a first-time hip replacement will receive the block, and their pain scores and opioid use will be tracked for 48 hours. The goal is to find a better way to manage post-surgery pain.
