Summary

This study planned to compare two types of nerve blocks (erector spinae block and quadratus lumborum block) for pain control after hip surgery in young people aged 15-30. The goal was to see if one block reduced opioid use or pain scores more than the other. However, the study was withdrawn before enrolling any participants, so no results are available.
