Figure 4.
(A-F) Tomography and three-dimensional reconstruction images of the femur in two groups on day 21. 3D reconstruction images revealed significant bone callus formation around the fracture site in the control group (A and B), while a large amount of callus formed away from the fracture site in the biofilm-infected group (D and E). The cortical bone in the infected group showed obvious corrosion and absorption (F), while in the control group it remained intact (C).
