The aim of this study is to evaluate an alternative projection of the Medial Coronoid Process (MCP) of the canine elbow joint. The projection (Di35M-PrLO) was, to my knowledge, first mentioned in an article by Haudiquet et al in 2002. In that article the projection was tested in vitro, and a good sensitivity was showed for the Medial Coronoid Process. The projection might be helpful in cases of suspected Fragmented Coronoid Process (FCP) . This study is divided into three parts. The first part is an in-vivo test of the projection, including technique and subjective evaluation of the outlining of the MCP. Part two is an in-vitro study of different positioning of the humerus in the Di35M-PrLO, in order to see which part of the MCP is best outlined in which position. Part three is an evaluation of the positioning technique, in order to see if the projection is usable in standard clinical situations. The study shows that the use of Di35M-PrLO flexed projection outlines the MCP sharper in 16 out of 24 cases, when compared to standard M-L flexed projection. In 5 cases the outlining was better in standard M-L, and in 3 cases no difference could be seen. The in-vitro study shows that a 20 degree angle of the humerus (the shoulder is at higher level than the elbow joint) gives an even better outlining of the MCP. This would give the projection the name RadioDi35M-PrLO-HumeroPr20M-DiL. The positioning technique is simple, and the technicians performing the radiographic examination had no problems during the study. In total the study shows that use of the Di35M-PrLO projection might give more information, and the au...
