A pragmatic single centre retrospective comparative review of complication profile between PEEK cages and Zero-P cage screw constructs.

In this short-term study, the standalone (SA) cages showed no difference in their complication profile in comparison to a cage-screw construct for both single and multilevel ACDF. Standalone cages might be a cost-effective option without increased complication risks. Nevertheless, we propose a longer-term follow-up with a prospective randomized trial for further evaluation of this finding.
