Abstract
Spinal instability due to degenerative pathologies in patients with metastatic cancer presents significant challenges when spinal fusion and post-operative imaging and radiotherapy are required. Traditional metallic hardware hinders imaging quality and radiotherapy precision due to metal artefact. Carbon-fiber-reinforced polymer (CFRP) implants offer a novel solution, combining mechanical stability with radiolucency to enhance post-operative multidisciplinary care. We present the case of a patient with metastatic cancer requiring spinal stabilization and fusion. To address the dual needs of spinal stabilization and radiotherapy planning, CFRP pedicle screws and rods were used. Postoperative imaging and radiotherapy planning benefited from the radiolucent properties of the implants, enabling precise tumor targeting and disease monitoring. This case highlights the advantages of CFRP implants in managing cancer-associated spinal instability. The radiolucent nature of these implants allows for high-quality imaging and optimal radiotherapy delivery, addressing limitations associated with metallic implants.
