title: Efficacy of anterior cervical fusion: comparison of titanium cages, polyetheretherketone (PEEK) cages and autogenous bone grafts.
abstract: This retrospective study was designed to analyze and compare the efficacy and outcomes of anterior cervical fusion using titanium cages, polyetheretherketone (PEEK) cages and autogenous tricortical bone grafts. Fifty-five patients who underwent segmental anterior discectomy with a follow-up period up to 12 months enrolled in this study. They were divided into three groups: titanium cage with biphasic calcium phosphate ceramic (Triosite; Zimmer, Berlin, Germany) in group A (n=27); PEEK cage with Triosite in group B (n=9); and autogenous tricortical iliac crest bone graft in group C (n=19). The fusion rates after 6 months were 37.21% in group A , 93.3% in group B, and 84.85% in group C. The fusion rates after 1 year in groups A, B, and C were 46.51%, 100% and 100%, respectively. The PEEK cage is a viable alternative to autogenous tricortical bone grafts in anterior cervical fusion.
