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 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 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 up with people who already had surgery using the BDyn device for lower back problems caused by worn-out discs or joints. The goal is to see how well the device works over a long time.
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 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.
