What this trial studies

This observational study aims to evaluate the clinical and radiographic outcomes of adult patients undergoing spine surgery for conditions such as spondylolisthesis and degenerative disc disease. Patients will receive the Viper Prime/Expedium spine system along with Fibergraft Bioactive Glass putty, which is designed to enhance the body's natural bone healing process. The study will follow participants for two years to assess fusion rates, complication rates, and the need for revision surgeries. This research addresses a gap in existing studies by specifically focusing on the outcomes associated with the combination of these implants.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with specific spinal conditions requiring fusion of 1-3 levels.

Not a fit: Patients with cervical spine pathology, spinal tumors, or those requiring fusion for more than 3 levels may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and recovery for patients undergoing spine surgery.

How similar studies have performed: Previous studies have shown success with the Viper Prime/Expedium systems, but this specific combination with Fibergraft is novel.
