Figure 1 Radiological stabilization, as indicated by an interval of <3 mm at the tip of spinous processes according to postoperative dynamic flexion (A) and extension (B) radiographs. (C) Solid bone fusion, as indicated by a bony bridge (arrowhead) at the reconstructive site on the sagittal sections of computed tomography scans.

Figure 2 The radiological stabilization rates determined using dynamic radiographs were not significantly different between the 2 groups at any time point postsurgery. N-PPC, non–Plasmapore-coated titanium cages; N.S., not significant; PPC, Plasmapore-coated titanium cages.

Figure 3 As demonstrated by reconstructive computed tomography scans, solid bone fusion rates in the PPC group were superior to those in the N-PPC group at 6 and 12 months. (※: P = .048, ※※: P = .005). There was no statistically significant difference between the 2 groups at 24 months postsurgery. N-PPC, non–Plasmapore-coated titanium cages; N.S., not significant; PPC, Plasmapore-coated titanium cages.
