Summary

This study tests a new, long-lasting painkiller (liposomal bupivacaine) that works for up to 72 hours after spine surgery, compared to the standard 6-8 hour painkiller. About 204 adults having lower back surgery will be randomly assigned to receive one of the two painkillers. The goal is to see if the longer-lasting option reduces the need for strong opioid pain medicines and improves pain control.
