HOW TO TAKE AND INTERPRET RADIOGRAPHS OF THE YOUNG PERFORMANCE HORSE
Fig. 3. Fetlock joint flexed lateral to medial projection. This horse has large irregularity in the middle of the sagittal ridge. This radiograph will be discussed by the panel as Case 3.
Fig. 4. Fetlock joint dorsolateral (30°) to palmaromedial oblique (elevated 10°). This horse has a large lateral proximal P1 pal- mar process fragment with two smaller intra-articular frag- ments. This radiograph will be discussed by the panel as Case 4.
Dorsolateral (30°) to palmaromedial oblique (elevated 10°) and dorsomedial (30°) to palma- rolateral oblique (elevated 10°) projections (Fig. 4). Areas of greatest concern on these projections are
the proximal-dorsal aspect of P1, the abaxial aspect of the superimposed sesamoid, the apex and suspen- sory branch attachment of the palmar/plantar sil- houetted sesamoid, and proximal P1. Abnormalities best identified on the fetlock oblique projections are listed below. If the RA is in bold type, it is the best projection to detect that RA.
