Animal models are unavoidable and indispensable research tools in the fields of bone tissue engineering and experimental orthopaedics. The fact that there is not ideal animal model as well as the differences in the bone microarchitecture and physiology between animals and humans are complicate factors and make model implementation difficult. Therefore, the tendency should be directed towards extrapolation of the results from one animal model to another or from animal model to humans. So far, this is the first paper which provides an overview on the microarchitecture of lower limb long bones and discusses data related to osteon diameter, osteon canal diameter and their orientation, as well as intracortical canals and trabecular tissue microarchitecture in commonly used animal models compared to humans depending on age, gender and anatomical location of the bone. Understanding the differences between animal model and human bone microarchitecture should enable a more accurate extrapolation of experimental results from one animal model to another or from animal models to humans in the fields of bone tissue engineering and experimental orthopaedics. Also, this should be helpful in making decisions on which animal models are the most suitable for particular preclinical testing.
