Clinical trials

This is an observational study designed as an extension of a prospective study conducted between 2012 and 2017. Patients who were originally enrolled in the initial study are being recontacted for follow-up assessment, including evaluation of clinical and radiological (MRI) criteria. Approximately 50 patients have been included to date and their long terms results (at least 9 years) will be assessed.

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.
