What this trial studies

This observational study collects real-world data to assess the safety and effectiveness of the Synergy cervical disc system in patients with cervical degenerative disc disease. It includes both prospective and retrospective cohorts, focusing on patients who have undergone or are scheduled for surgery involving the Synergy Disc. The study aims to gather insights on patient outcomes following the implantation of the disc system after discectomy procedures.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 and above who are undergoing surgery for cervical disc issues and have experienced intractable radiculopathy or myelopathy.

Not a fit: Patients with moderate to advanced spondylosis, osteoporosis, or active systemic infections are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable information on the effectiveness of the Synergy cervical disc system, potentially improving treatment options for patients with cervical degenerative disc disease.

How similar studies have performed: While this study focuses on a specific device, similar observational studies have shown success in evaluating the performance of spinal implants, suggesting a potential for meaningful insights.
