Equine Podiatry. The specialty dealing with the equine hoofthe hoof capsulecoronary bandall anatomical structures with in the hoof capsuleall tendons that affect the hoof Requires the veterinarian and trimmer or farrier to work together. What does the horse need?. A veterinarian and a trimmer or farrier team who are willing to work togetherA team that enjoys podiatry and is committed to doing their best work .

2. Equine Podiatry The specialty dealing with the equine hoof
the hoof capsule
coronary band
all anatomical structures with in the hoof capsule
all tendons that affect the hoof
Requires the veterinarian and trimmer or farrier to work together
3. What does the horse need? A veterinarian and a trimmer or farrier team who are willing to work together
A team that enjoys podiatry and is committed to doing their best work
4. What does a farrier or trimmer need from the veterinarian? A veterinarian
who understands what is healthy and what is not
who understands diseases affecting the hoof
who can consistently take an informative radiograph of the foot
who is willing to work as part of a team
Take the time to show him the radiographs
Pre- and post- trimming or shoeing
Learn to speak the same language
Many overlapping terms
5. “Quality radiographs are to podiatry what ultrasound is to reproduction”
6. Traditional Radiography of the digit
7. Traditional Radiography Beam focused at coronary band
Foot packed
Ground surface not always demarcated
Dorsal hoof wall marked with rigid object
Apex of frog and heels not marked
Hoof not always directly against cassette
8. Is this what we are after?
9. Lacks information for the farrier trimmer!
10. Radiographic GOALS Consistent informative films
Take the same view every time
Ability to monitor small changes with accuracy
Evaluate the soft tissues of hoof
Evaluate P3’s relationship to capsule and ground
Evaluate how the bone and the soft tissues relate to each other
How the bone and soft tissue relate to the ground
Learn common parameters of breeds
What is common is not necessarily healthy
Horses have only rarely been bred for hoof quality
Popular breeds are notorious for poor hoof health
11. Radiography for Shoeing and Trimming Center on bottom of P3, not coronary band
measure sole depth
Palmar/plantar angle
medial to lateral balance of P3
Clearly demarcate (with barium paste)
Dorsal hoof wall – care to start paste exactly on hairline
Lateral heel bulb – care to start paste exactly on hairline
Apex of frog
Clearly demarcate ground surface – lead in wooden block
Hoof touching cassette
Heel bulbs parallel to primary beam and perpendicular to cassette
Do not pack the foot
Measure sole depth
Standardize distance from film to machine
12. Methods Center on bottom of P3
Blocks match machine
metal wire in top
Barium paste on dorsal hoof wall
Barium on apex of frog
Barium on heel
13. Much better Centered bottom of P3
Dorsal hoof wall marked
Ground Surface Marked
Not packed
Heel marked
Apex marked
Note: -ok that bone is too light, not as worried about boney detail here as relationship of the bone to the soft tissues and ground

29. Parameters on a lateral view
30. Evaluation of Lateral View Horn: Laminar Zone
Should be uniform ( < 20 mm)
CE zone - <1 cm
coronary band - extensor process
“halo effect”- coronary band invagination
Sole depth
mass (> 10 mm)
Cup
Black area between sole and ground surface
31. Evaluation Lateral View Palmar Angle
Angle formed between palmar surface of P3 and ground
The horse wants it positive 3-9 ş
Digital Breakover
distance from the tip of P3 to where hoof breaks forward
The horse wants it short, maybe even negative?
The horse wants it optimized.
Bone Angle
angle formed between dorsal and palmar surfaces of P3
32. Horse in a Cast with digital radiography
33. Anterior – Posterior projection Looking for medial lateral balance of P3
Uniformity of joint spaces
Is the medial and lateral coronary band level
Evaluate growth rings if use barium
34. Anterior posterior view
35. Moral TAKE the radiograph the correct way
Evaluate the parameters
Use the film to make goals
Evaluate whether goals were met
Work together!!!!
