Figure 1: Pathogenesis of postoperative discitis: (left to right) Inoculation of bacteria into the disc space → bacteria proliferating (1 week) → increased vascularity and early granulation tissue formation in the vertebral endplates (2 weeks) → granulation tissue formation (3 weeks) → appositional bone formation starts and granulation tissue invades the disc space (6 weeks)
