Post-operative analgesia and spinal block duration following total hip arthroplasties - comparison of single-shot intrathecal ropivacaine, and bupivacaine: a randomized, double blinded controlled study

This study compares two common pain medications, ropivacaine and bupivacaine, used in spinal injections for hip replacement surgery. Researchers want to see which one helps people recover sensation and movement faster after the operation, and how well they control pain.
