What this trial studies

This observational study aims to evaluate the clinical and radiographic outcomes of patients with degenerative disc disease and instabilities in the cervical and lumbar spine who receive conduit cages and Fibergraft Bioactive Glass (BG) Putty. The study will recruit skeletally mature patients with specific spinal pathologies and follow them for two years to assess the effectiveness of these implants in restoring intervertebral height and facilitating fusion. The research focuses on patients with conditions such as herniated discs and pseudarthrosis, providing a comprehensive analysis of their recovery and outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with diagnosed degenerative disc disease or herniated discs affecting specific levels of the cervical or lumbar spine.

Not a fit: Patients under 18, those with a high BMI, or individuals with previous failed spinal surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance spinal fusion outcomes and improve recovery for patients with degenerative disc disease.

How similar studies have performed: Previous studies have explored the use of conduit cages in spinal procedures, but this specific combination with Fibergraft has not been extensively tested.
