Perioperative Analgesic Effects of PENG Versus PENG Plus LFCN Block in Hip Surgeries
Turkey (Türkiye)72 participantsStarted 2025-11-01
Plain-language summary
This study is designed to find the best way to control pain after hip surgery performed through a side (lateral) incision. Two different types of nerve blocks used before the operation will be compared.
In one group, patients will receive a Pericapsular Nerve Group (PENG) block, which numbs the main nerves that carry pain signals from the hip joint. In the other group, patients will receive a PENG block together with a Lateral Femoral Cutaneous Nerve (LFCN) block, which adds extra pain relief for the skin and outer part of the thigh.
A total of 72 patients between 18 and 80 years old will take part in this study. All operations will be done under spinal anesthesia. Pain levels will be measured several times during the first 24 hours after surgery using a simple 0-10 pain scale. Patients will receive pain medicine through a pump that allows them to press a button when they feel pain. The total amount of medicine used will be recorded.
The researchers will also monitor when patients first need pain medicine, when they can start walking, how satisfied they are with pain control, and if they experience side effects such as nausea or dizziness.
By comparing the two methods, the study aims to see whether adding the LFCN block to the PENG block provides better pain control, lower drug use, faster recovery, and higher patient comfort after hip surgery.

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?

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?
