Resumo

Introdução: O sistema CAVUX® Facet Fixation System (FFS) representa uma alternativa minimamente invasiva para fusão e estabilização cervical posterior, promovendo artrodese interfacetária por via percutânea. Embora já utilizado em outros países, não há relatos publicados sobre sua aplicação no Brasil. Relato dos casos: Apresentamos a primeira experiência brasileira com o uso do CAVUX® FFS em três pacientes com dor cervical axial e cervicobraquialgia refratárias após artrodese anterior prévia. Todos apresentavam estenose foraminal em múltiplos níveis e foram submetidos à fixação posterior percutânea interfacetária em três níveis cervicais. Os procedimentos foram realizados sob anestesia geral, com monitorização eletrofisiológica e uso de dois arcos em radioscopia, apresentando tempo cirúrgico médio de 1 hora, sangramento estimado médio de 50 mL e alta em até 24 horas. Em três meses, observou-se redução consistente da dor e melhora funcional significativa, sem complicações neurológicas ou intercorrências intraoperatórias. Conclusão: O CAVUX® FFS mostrou-se seguro, tecnicamente viável e eficaz para estabilização cervical posterior, com recuperação rápida e mínima morbidade. Este relato inaugura o uso documentado do sistema no Brasil e amplia o conhecimento nacional sobre técnicas de fusão cervical minimamente invasiva.

Abstract

Introduction: The CAVUX® Facet Fixation System (FFS) represents a minimally invasive alternative for posterior cervical fusion and stabilization, enabling percutaneous interfacet arthrodesis. Although used internationally, no prior studies have documented its application in Brazil. Case presentation: We report the first Brazilian experience using the CAVUX® FFS in three patients with persistent axial neck pain and cervicobrachialgia following previous anterior cervical arthrodesis. All presented multilevel foraminal stenosis and underwent posterior percutaneous interfacet fixation at three cervical levels. Procedures were performed under general anesthesia with intraoperative neurophysiological monitoring and dual C-arm fluoroscopy, with a mean surgical time of one hour, estimated blood loss of 50 mL, and hospital discharge within 24 hours. At 3-month follow-up, all patients demonstrated consistent pain reduction (mean VAS 9→4) and functional improvement, with no neurological complications or intraoperative events. Conclusion: The CAVUX® FFS proved to be a safe, feasible, and effective technique for posterior cervical stabilization, offering rapid recovery and minimal morbidity. This report documents the first national use of the system and expands regional knowledge of minimally invasive posterior cervical fusion techniques.
