The nanohydroxyapatite/polyamide‐66 (n‐HA/PA66) cage is a novel bioactive nonmetal cage that is now used in some medical centers, while the polyetheretherketone (PEEK) cage is a typical device that has been widely used for decades with excellent clinical outcomes. This study was performed to compare the long‐term radiographic and clinical outcomes of these two different cages used in transforaminal lumbar interbody fusion (TLIF).
