Reduce adjacent back pain after lumbar surgery
Part of Bones, joints & muscles clinical trials.
This trial looks at whether a limited decompression (a careful nerve-space “freeing” procedure) can help prevent future problems in the spinal level next to your planned surgery. It targets people with spinal canal narrowing next to the surgery level but who do not yet have symptoms there.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have lumbar spinal stenosis (narrowing in the low-back canal) and your planned surgery is at L4 to S1
- The level next to your surgery (L3/4) has narrowing but you do not have symptoms there, with mild fluid-blocking on imaging (CSF blockage grade 1)
- You tried non-surgery treatments for at least 8 weeks and they did not help enough
- Your spine does not have instability at the adjacent level (no slip/turn/side-bend problems at L3/4)
- You do not have an infection or tumor in the low back, and you have no prior lumbar fusion surgery

This study looks at how well lumbar fusion surgery works long-term when the joint just above or below (adjacent segment) already shows wear-and-tear. It may help predict who benefits most and guide treatment planning.
This study compares two types of back surgery for people with narrowing of the spinal canal in the lower back that has not improved with non-surgical treatment. The goal is to see which surgery gives better relief and recovery.
This trial tests a special implant (FFX®) that stabilizes the lower spine while relieving pressure on nerves in people with spinal stenosis. It's for patients who need surgery but have not had previous back surgery and whose pain has not improved with conservative care.
This study tests whether surgery can relieve leg or back pain caused by narrowing of the spinal canal next to a previous back fusion. If you have persistent symptoms despite other treatments, this trial may help you decide if surgery is right for you.
This study compares two treatments for people who have narrowing of the spine above a previous back fusion. One option is just removing the pressure on the nerves, and the other is also extending the fusion. It aims to see which works better for symptoms like leg pain or cramping when walking.
This trial compares outcomes after decompression surgery for one affected area in the lower back, with and without adding spinal fusion. It may help patients avoid unnecessary extra surgery—or ensure fusion is used when it’s needed.
