OSTEOLYSIS
The main focus of our research was the fusion of the AlIn the present study, the fusion rate of 88.2% in AlFiniels reported in 2004 an average fusion rate of 95% at 6 months and 100% at one year after ACDF with AlAccording to CT scans in our study, the fusion starts mainly inside the PEEK cages, where there are two bioactive void filler inserts, whereas the porous cages integrate with the bone along the surfaces. The difference in the process of fusion can be explained by different cage structure and composition.Ceramic AlWe separately assessed the achievement of grade I fusion, which is complete bilateral fusion from a radiological point of view. However, without knowing the correlation with clinical outcomes, we cannot assess the clinical significance of this complete fusion achievement.Peri-implant osteolysis was more common in the PEEK group. There is no literature evidence of osteolysis around the AlThere may be some possible limitations to this study. The first, method of randomization, did lead to the formation of unequally sized groups. Allocating more patients (with a 2:1 ratio) to the group with an Al
