Long-term Assessment of BDyn Dynamic Stabilization Device in Patients With Lumbar Degenerative Disc Disease (MOBIDYN)
5 de mayo de 2026 actualizado por: Cousin Biotech
The goal of this clinical trial is to estimate the cumulative reoperation rate at upper adjacent segment level in patients treated with BDyn dynamix stabilization for lumbar degenerative disc diseases over long-term follow-up.
Patients will provide baseline socio-demographic and surgical data, complete patient-reported outcome measures (ODI, pain NRS, satisfaction), undergo imaging assessments (dynamic X-rays, EOS, MRI), and participate in safety evaluations including adverse event monitoring throughout follow-up.

Experimental: Patients treated with BDyn dynamic stabilization
All enrolled patients undergo lumbar dynamic stabilization using the BDyn device.
Clinical, radiological, and patient-reported outcomes are collected during long-term follow-up.
|
BDyn is intended for spine surgery with a posterio approach.
The sterile spinal dynamic posterior stabilization devices BDyn is intended to restore the stabilization of the spine segment from T10 to S1 by preserving the anatomical lordosis and the deadening of the intervertebral joint.
