Stallion Licensing X-ray Requirements

2019 X-RAY PROTOCOL

• P3/Navicular (Fore limb only)
  • Lateromedial (Must be elevated on a block to evaluate the entire hoof).
  • 60° dorsoproximal-palmardistal oblique, commonly known as a DV (Must have clear interpretation of the navicular bone, shoes must be removed if unable to view the navicular bone in its entirety).
• Fetlock
  • Lateromedial (flexed in fore limb, standing in hind limb, clearly visualizing the sagittal ridge of the distal cannon).
  • Dorsal 10° proximal-palmar/plantarodistal oblique, commonly known as an AP, or DP (elevating seasmoids apart from P1 visualizing the distal cannon).
• Tarsus
  • 45° dorsomedial/posteriorlateral oblique (highlighting the distal intermediate ridge of the tibia and the distal lateral trochlear ridge of the talus).
  • Dorsoplantar view at 10° lateral (highlighting the medial malleolus of the distal tibia).
• Stifle
  • Lateromedial (including the patella)
  • Caudal 60° lateral-craniaomedial oblique (highlighting the medial femoral condyle in its entirety).

• There is no longer a grading system. Based upon the findings of the three-veterinarian panel, the stallion’s x-rays will be determined to be either acceptable (i.e. horse may proceed to the licensing) or not acceptable (horse will be withdrawn from the licensing). A description of the radiographic findings will be documented.
• Any invasive joint surgery that has been performed must be reported when the radiographs are submitted. Pre-operative radiographs of the specified joint or joints must be included.
• With regard to OCD: Stifles must be free from positive finding. Bilateral OCD fragments in the tarsi are not acceptable. Severe/extensive OCD fragments in a tarsus or a fetlock are not acceptable. One fragment in a tarsus and one further joint, excluding the tarsus or stifle, is acceptable.
• Stallions will not be deemed acceptable with severe navicular or spavin changes.
