Ununited anconeal process, osteochondrosis, and fragmentation of the coronoid process (FCP), separately or together, comprise canine elbow dysplasia. Radiographic detection of ununited anconeal process or osteochondrosis is common, whereas identification of an FCP is often inferred by finding joint incongruity and secondary changes. Early identification of FCP can be improved by evaluating the elbow joint for subtle changes visible early in the course of this disease. Proper radiographic technique and positioning are essential in optimizing identification of the changes associated with mild or early FCP.
