In Vivo MicroCT Monitoring of Osteomyelitis in a Rat Model

Figure 6

(a, b) Two inoculated specimens showing different conditions at day 28: (a) in this specimen, some bone-implant contact and cortical fixation were preserved at day 28. (b) Total loss of bone-implant contact, peri-implant bone stock leading to a fully loosened screw. (c, d) Example of an animal showing reformation of pseudocortical bone around the screw after a quasicomplete osteolysis: (c) at 6 days, very little cortical bone is left in contact with the screw thread. Pullout force is reduced significantly. (d) At day 20, we observe a neocortical formation and bone-implant contact, restoring partially the screw fixation.
