Medial coronoid disease (MCD), a component of canine elbow dysplasia, is the most common cause of thoracic limb lameness in juvenile medium- to large-breed dogs. The goal of this study is to describe the magnetic resonance imaging (MRI), arthroscopic and histopathological changes in dogs with medial coronoid disease and to identify potential relationships between these findings. Twenty-five diseased medial coronoid processes (MCP) were collected from 19 dogs with a confirmed diagnosis of medial coronoid disease that underwent surgical management with subtotal coronoid ostectomy. A reference group of normal MCPs was harvested from 9 dogs that were euthanatized for reasons unrelated to elbow disease. MCP specimens were evaluated by magnetic resonance imaging (MRI) using a novel grading scheme (all dogs), arthroscopy using a modified Outerbridge scheme (affected dogs only) and histopathology (all dogs). The common histopathologic findings were subchondral microfractures, subchondral microfractures continuous with cartilaginous fissures, moderate to severe hypercellularity of the marrow space, trabecular bone necrosis and articular cartilage degeneration. The severity of cartilage disease in the MCP was moderate to severe in most of the specimens, even in cases with minimal arthroscopic pathology. Three distinct patterns of bone marrow lesion (BML) were identified adjacent to the MCP, but there was no correlation between BML pattern and either histopathological or arthroscopic findings. There was moderate correlation between modified Outerbridge scores and MRI scores. No correlation was identified between the histopathological changes and either MRI or arthroscopic scores. There was no significant correlation between the clinical scores and histopathological changes. Ongoing improvements in the resolution of noninvasive imaging techniques will likely improve description and understanding of the MCP disease in dogs.
