Figure 4

Evaluation of macroscopic features (AD) and X-ray (A’D’) of defects in the femur bone rats (arrows). Groups: G1: Control—no implant; G2: Co—Co-28Cr-6Mo alloy; G3: Co PIII- Co-28Cr-6Mo with surface nanostructured by PIII; G4: Co+Ti PIII—Co-28Cr-6Mo alloy surface coated with Ti and nanostructured by PIII. Macroscopic images do not show any focus of infection or inflammatory process. The radiographic images show correct positioning of the metallic implants (MI) in the G2, G3, G4 groups as well as their radiodensities.
