Comparative Study Between the Cervical Cage with Screws and the Classical Cage in Anterior Cervical Discectomy and Fusion

Background: Anterior cervical discectomy and fusion (ACDF) remains the gold-standard surgical treatment for cervical disc disease (CDD). Stand-alone zero-profile (Zero-P) cages with integrated screws provide low-profile fixation, potentially reducing complications such as implant subsidence compared to traditional cages. However, comparative data on clinical and radiological outcomes between these cage types remain limited, particularly in short- and intermediate-term follow-up systems.
