The elbow joint in dogs constitutes a complex interaction of three bones, the humerus, radius and ulna. Medial coronoid disease (MCD) is a common cause of lameness in dogs, i.e. fracturing of the most prominent portion of the ulnar joint surface driven in flexion and in pivot against both the humerus and the radius. The cause remains unknown, but prior studies suggest joint incongruency as an important factor in disease development [2]. The goal of this study was to develop a functional geometrically valid model in COMSOL Multiphysics® to better predict where fractures could occur in vivo. Preliminary results indicate high stress concentrations in the area where MCD occurs clinically. With this model, multiple geometric abnormalities will be tested in order to better understand MCD.
