Ultrasound-Guided Proximal Superior Cluneal Nerve Block for Superior Cluneal Nerve Entrapment
Turkey (Türkiye)40 participantsStarted 2026-05-15
Plain-language summary
Superior cluneal nerve entrapment (SCNE) is an underrecognized cause of chronic low back pain and gluteal pain that may mimic lumbar spine disorders. Ultrasound-guided proximal superior cluneal nerve block has increasingly been used in routine clinical practice .Diagnostic superior cluneal nerve block is commonly used to confirm the diagnosis, whereas ultrasound-guided proximal superior cluneal nerve block has emerged as a therapeutic option.
This prospective observational cohort study aims to evaluate the clinical outcomes of ultrasound-guided proximal superior cluneal nerve block in patients with clinically diagnosed superior cluneal nerve entrapment who undergo the procedure as part of routine clinical care. Pain intensity, disability, and neuropathic pain characteristics will be assessed at baseline and during follow-up to evaluate treatment outcomes.

* At least 50% reduction in pain intensity following diagnostic superior cluneal nerve block.
* Failure of conservative treatment.
* Ability to provide written informed consent.
Exclusion Criteria:
* Previous superior cluneal nerve surgery.
* Active local or systemic infection.

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.
1This trial is specifically for superior cluneal nerve entrapment — how confident are you that my chronic low back pain is actually caused by this condition, and is that something we should confirm before I consider this study?
2The trial uses ultrasound-guided nerve blocks, which is a procedure rather than a medication — what are the realistic risks or side effects of having a nerve block in that area of my lower back?
3Since this trial is listed as Phase NA, which often applies to procedure-based studies, what does that mean for how much is already known about the safety and effectiveness of this specific ultrasound-guided approach?
4The primary thing being measured is change in pain intensity — if my pain does or doesn't improve during the trial, how would that affect my ability to switch to or continue other treatments for my back pain?
5Are there standard, non-experimental treatments for superior cluneal nerve entrapment that I should try first before discussing whether this trial might be worth considering?
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.
