PEEK Cages versus PMMA Spacers in Anterior Cervical Discectomy: Comparison of Fusion, Subsidence, Sagittal Alignment, and Clinical Outcome with a Minimum 1-Year Follow-Up

<table>Fusion and nonfusion. Postoperative three-dimensional reconstructed CT scans after ACD with implantation of PEEK cages. (a) A continuous trabecular bone bridge through the cage (encircled) confirmed bony fusion; (b) no bony fusion was assessed due to the lack of continuous trabecular bone bridges.</table>
