Methods
inflammation, injury of the cervical spine, neurological cervicobrachial symptoms
INFLAMMATION, CERVICAL DISC DEGENERATION, SPONDYLOARTHRITIS, SPINAL INSTABILITY
This prospective, controlled observational, monocentric study was conducted between 2015 and 2021. We hypothesized that a porous bioceramic AlPorous AlPEEK cageAll adult patients with symptomatic cervical disc degeneration scheduled for elective one-level ACDF between October 2015 and November 2019 were selected for study enrolment. The inclusion criteria for the study were the following: (1) indication for one-level ACDF predominantly; (2) neurological cervicobrachial symptoms correlated with graphical findings; (3) failure of conservative treatment. Patients were not enrolled or were excluded if any of the following exclusion criteria were met: (1) signs of spinal instability at the indicated level; (2) local inflammation or spondyloarthritis; (3) previous injury of the cervical spine; (4) previous ACDF surgery at any other level; (5) non-availability for FU or inability to complete assessment.Initially, 111 patients were included to this study. The unequal allocation randomization method was used for this study. Patients were randomly assigned to one of two groups: ACDF with an AlFlow diagram of the study
