The Study of the Radiographic Positionings of the Canine Elbow for Identifying the Medial Coronoid Process

Abstract

Twenty cadaver canine forelimbs, 9 right and 11 left, were used to evaluate the most effective radiographic position that can enhance the cranial aspect of the medial coronoid process (MCP) of the ulna. A lead pellet (1 mm) was buried to represent the area representing the cartilegenous fragment in the canine patient in the fragmented medial coronoid process (FMCP). The distance between the pellet and the radial surface and the superimposition of the humeral condyle silhouette on the pellet were used as parameters for analysis. The results showed that the disto45 medialproximolateral oblique (Di45M-PrLO) position with a 40 flexed elbow had not only the least distance between the pellet and the radial surface but also the least superimposition of the humeral condyle silhouette on the pellet. In conclusion,
the Di45M-PrLO position with a 40 flexed elbow is the best position for viewing MCP radiography in a dog with suspected FMCP.
