Stallion Licensing X-ray Requirements
The American Hanoverian Society’s x-ray protocol is based upon the society’s studbook reciprocity with the Hannoveraner Verband. In order to proceed to the licensing, the owner of a stallion candidate must provide the following required radiographic views:
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will be determined to be either acceptable (i.e. horse may proceed to the licensing) or not acceptable (horse will be withdrawn from the licensing).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.
Radiographs may be delivered by one of two ways:
- Studies may be emailed in DICOM format to radreport@roodandriddle.com. JPEG images will not be accepted.
- Radiographs in DICOM format on a CD, containing a single study, can also be shipped via Federal Express to:
Rood & Riddle Equine Hospital
Attn: Lauren Jeter
2150 Georgetown Road
Lexington, KY 40511 Tel: (859) 280-3407
You must include the return address of the veterinarian who is legally responsible for the radiographs so that they may be returned. Owners requesting a review of radiographs must contact Lauren Jeter at Rood and Riddle prior to receipt of radiographs to set up an account for billing purposes. Reports will not be distributed to the AHS until payment has been made in full for the interpretation services.
