Figure 3. — Computed tomography coronal images of representative cases. (A) Early TBR-positive (arrow) case using Tn cages. (B) Early TBR-positive (arrow) case using TiP cages. (C) A case that changed from VEC-positive/TBR-positive to VEC-negative/TBR-positive status. Three months postoperatively, the central cyst was enlarged (arrowhead) but was also TBR-positive (arrow). One year postoperatively, the cyst had shrunk, and bridging bone (arrowhead) had developed, confirming bony fusion. (D) VEC-positive/TBR-negative case with CZPS. Three months postoperatively, cysts had developed (arrow), and TBR was not present. One year postoperatively, the cysts were enlarged, and cage subsidence (arrow) and CZPS (arrowhead) were observed. (E) A case of bony fusion with cage subsidence using Tn cages. Three months postoperatively, cage subsidence occurred (arrowhead), but the cage that had not subsided was TBR-positive (arrow). One year postoperatively, a bridging bone (arrowhead) had developed, confirming bony fusion. Abbreviation: TBM, trabecular bone remodeling; VEC, vertebral endplate cyst; CZPS, clear zone around pedicle screw.
