B-DYN device versus standard fusion for lumbar stenosis
Part of Bones, joints & muscles clinical trials.
This trial compares a specific spinal fusion approach (B-DYN) with the standard fusion surgery for people with lumbar spinal stenosis. It aims to improve function after surgery and check whether the newer approach is well tolerated.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your MRI shows lumbar stenosis affecting 1, 2, or 3 disc levels (or certain central + side narrowing patterns).
- You have leg symptoms from nerve irritation (neurogenic claudication), with pain level score over 30.
- Your symptoms have lasted more than 3 months and did not improve with well-managed non-surgical treatment.
- You’re at least 40 years old and can answer study questionnaires in the study language.
- Your spine alignment fits: you have no serious slip at the top level (spondylolisthesis grade 1 or none).
- You should not need surgery on more than 3 disc levels, and you must have no major fusion/surgery safety reasons.

This trial tests a new implant to treat lower back narrowing that causes pain. It may help people who have not improved after at least 3 months of non-surgical care.
This trial tests a less invasive spinal surgery using an endoscope (a small camera) to treat certain spine problems without fusing bones together, which may help you recover faster. It is for adults with specific types of back or leg pain from conditions like a failed previous fusion, a slipped vertebra, or a curved spine with narrowing.
This study follows patients who received a BDyn device (a flexible spine stabilizer) between now and December 2021 to check how well it works over time and whether any problems develop. It helps doctors understand if the device safely relieves back pain and improves movement in the long run.
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 a spinal fusion surgery is better than staying with non-surgical treatments for people with long-term, severe low back pain from worn-out discs in the lower spine. It aims to find out which approach offers better pain relief and quality of life.
This trial tests a new spinal implant system (CORUS-LX) for fusing two lower back discs that are causing pain. It is meant for people with severe, long-lasting back or leg pain that hasn't improved with non-surgical treatments.
