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 trial compares two different surgical techniques for treating a narrowed spinal canal (stenosis) in your lower back. The goal is to determine which approach works better for reducing pain and improving function.
This study tests a second surgery to relieve pain or numbness in the area next to a previous back fusion. It is for people whose symptoms have not improved with other treatments and who have spinal stenosis confirmed on an MRI.
This study tests whether removing pressure on the nerves (decompression) is enough, or if adding more fusion surgery is better, for patients who develop spinal stenosis next to an old fusion.
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.
This trial tests whether removing pressure on spinal nerves alone, without any hardware, can help fix spine balance and reduce pain in people with lumbar stenosis. It is for those who have had leg pain or trouble walking for at least 3 months and plan to have surgery without implants.
