Long-term Assessment of BDyn Dynamic Stabilization Device in Patients With Lumbar Degenerative Disc Disease
Starting soon · Not applicable
Conditions studied: Degenerative Disc Disease
In brief
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.
