Prevalence of Neuropathic Pain After Non-instrumented Lumbar Spinal Surgery
France39 participantsStarted 2024-07-01
Plain-language summary
Chronic neuropathic pain following lumbar spine surgery is often under-diagnosed and difficult to relieve. It can persist long after the operation, sometimes for months or even years, and has a major impact on the quality of life of patients who suffer from it. However, the scientific literature on the subject remains relatively poor, as evidenced by the absence of scientific studies on the prevalence of neuropathic pain after lumbar spinal surgery, whether instrumented or not.
The main aim of this study is to determine whether lumbar spine surgery has an impact on the prevalence of neuropathic pain. Participants will be followed up and complete a quality-of-life questionnaire for one year after surgery.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria:
* Patients admitted for scheduled primary lumbar spine surgery without pedicle osteosynthesis or interbody cage.
* Pathology concerned by programmed surgery: herniated disc or lumbar spinal stenosis, uncomplicated by motor or sphincter deficits.
* Delay between 1st painful symptoms and surgery \> 48h.
Non-inclusion criteria:
* Surgery scheduled within 48 hours of onset of symptoms.
* Presence of cauda equina syndrome
* Presence of motor-radicular deficit
* Patients with neurological pathology prior to surgery
* Major cognitive or sensory disorders preventing completion of the self-questionnaire
* Patients under guardianship
* Patients not covered by French social security.
* Patients who develop an identified neurological pathology after surgery, regardless of the initial surgery (e.g. multiple sclerosis, spinal cord injury, etc.).
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
