Evaluation of a Carbon Fiber Device for Spinal Surgery

Carbofix Pedicle Screw System: Randomized Clinical Trial to Evaluate the Clinical and Radiographic Outcomes of the Use of a Carbon Fiber Device Compared to Titanium Devices in Patients Undergoing Spinal Arthrodesis for Degenerative Spinal Diseases

Not applicable Interventional Istituto Ortopedico Rizzoli · NCT06209684

This study is testing a new carbon fiber device for spinal surgery to see if it works better than traditional titanium screws for patients with degenerative spinal diseases.

What this trial studies

This study evaluates the clinical and radiographic outcomes of using a carbon fiber pedicle screw system compared to traditional titanium devices in patients undergoing spinal fusion for degenerative spinal diseases. It aims to assess the effectiveness of the carbon device, which has previously shown promise in cancer patients due to its low interference with radiation and superior imaging capabilities. A total of 118 patients requiring 1 or 2 levels of lumbar or lumbosacral fusion will be included in the evaluation. The study seeks to fill a gap in the literature regarding the use of carbon fiber in lumbar degenerative pathologies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older suffering from degenerative spinal pathology or spondylolisthesis requiring instrumented stabilization.

Not a fit: Patients with metabolic bone diseases, neoplastic diseases, or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and more effective option for spinal stabilization in patients with degenerative spinal diseases.

How similar studies have performed: While previous studies have shown the effectiveness of carbon devices in cancer patients, this approach in degenerative spinal conditions is novel and has not been extensively tested.
