TLIP Block Versus Retrolaminar Block on Quality of Recovery After Posterior Lumbar Spine Fusion Surgery
Egypt70 participantsStarted 2026-06
Plain-language 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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
