Long bone fracture constitutes a common reason for medical consultation within veterinary orthopaedic services. Owing to the specificities of the veterinary field, post-operative complications after a fracture osteosynthesis are usually more numerous than those in human medicine, and therefore, there is a need to better understand which orthopaedic device(s) should be preferred for a given fracture. The interest of subjectspecific finite element (FE) simulations in the understanding of long bone mechanics has been largely emphasised (Helgason et al. 2008; Schileo et al. 2008). However, available studies are often limited by the many assumptions made throughout the procedure of creating a validated subject-specific FE model of a long bone, including geometry acquisition and modelling, assignment of realistic material properties and accurate validation of FE results based on ex vivo experiments. Particularly, fracture prediction has often been limited to the fracture onset prediction based on arbitrary criteria. Based on these previous studies, the objective of the present contribution is to propose and compare different subject-specific FE models of long bones that could accurately predict long bone response and failure.

Humeral condylar fractures are common in dogs. Different types of fractures (lateral, medial, bicondylar) may occur, depending on the age of the dog and the position of its elbow during the impact. The goal of this work is to understand the effects of bone posture and skeletal development on canine humeral fractures by means of the finite element method. Four distinct finite element simulations were performed, corresponding to an immature and a mature dog elbow, respectively in extension and flexion. To create the finite element models, subject-specific finite element meshes were extracted from the CT-data. Appropriate material properties were used for cortical bone, trabecular bone and cartilage. The modified Mohr-Coulomb failure criterion was implemented to take account for strength asymmetry. Lateral humeral fractures are obtained for both the young and adult dog elbow, in extension and flexion. This is in agreement with clinical observations, in which lateral condylar fractures are most common. [less ▲]
