Summary

This prospective randomized controlled study aims to compare the effects of ultrasound-guided thoracolumbar interfascial plane (TLIP) block versus retrolaminar block on postoperative quality of recovery in patients undergoing posterior lumbar spine fusion surgery. Despite advances in surgical techniques, lumbar spine fusion is associated with significant postoperative pain, which may delay recovery and increase opioid consumption.

Recent approaches emphasize multimodal analgesia and opioid-sparing strategies, including regional anesthesia techniques. Interfascial plane blocks, such as TLIP and retrolaminar block, have gained attention due to their safety and effectiveness in targeting the dorsal rami of spinal nerves supplying the posterior spinal structures.

The primary outcome of this study is postoperative quality of recovery assessed using the Quality of Recovery-15 (QoR-15) questionnaire at 24 hours. Secondary outcomes include pain scores, opioid consumption, time to ambulation, time to oral intake, and postoperative complications.
