Radiographical images (anteroposterior) of the non-infected and infected IMT groups at the end of the study. (A) IMT non-infected, n = 6; (B) IMT infected, n = 6. (C, D) Quantification of bone healing in the different groups using RUST of the anteroposterior and lateral radiographs of the rabbit humerus at (C) 6 weeks and (D) end of the study. A RUST value > 10 is considered as healed osteotomy, RUST value < 6 is considered as not healed osteotomy, RUST values between 6–10 are considered neither union nor definite non-union. White arrows indicate representative cases of bone forming around the outside of the scaffold. Statistical analyses were performed using Mann Whitney test, no significant differences were measured. Error bars indicate SD
