To date, variations in the protocols for long-bone tibia segmental defect models, such as the age and sex of the animals, bone stabilisation device, postoperative procedures and appropriate controls, have prevented the development of a standardised large animal long-bone defect model (Cipitria et al., 2013; Fernandes et al., 2014; Pobloth et al., 2017). models 3,647 views.
