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>Patient flow diagram. Out of 225 patients with ACD between January 2005 and February 2009, 107 patients were included in one PEEK cage group and two PMMA groups. ACD: anterior cervical discectomy, PEEK: polyetheretherketone, and PMMA: polymethylmethacrylate.</table>
