Farrier for Vets Flashcards
Why are horses trimmed?
Remove excess length, remove distortion, improve base support, prevent chipping, remove disease/deteriorated areas
Why do horses wear shoes?
Protection, treatment, traction and to alter gait
What are some consequences of horse shoes?
Increased shock/concussion to distal limb, traumatic hoof wall loss, puncture wound from chip or nail, sprung or twisted show, injury if kicked, nail too close to sensitive structures
What does a perfect foot look like?
-Symmetrical
-Thick bars (terminate at widest part of foot)
-Big frog takes up 60% length
-Healthy sole
Thick hoof wall
What is the key to trimming or shoeing a horse?
Load the healthy structures
How should you trim a foot for a shoe?
Flaten it (lead wall rounded (45 degree) for barefoot)
What is the ideal hoof patern axis?
Matched
What is an underrun heel?
More than 5 degree difference between the dorsal hoof wall and heel angle
(Heel 1/3 distance of dorsal hoof wall)
Growth ring matched and uniform
Where should the widest part of the hoof be?
Widest point behind the frog (3/4 to inch behind) - horse shoe half in front and behind
-Directly down from the distal condyle P2
What is key when assessing your hoof-pastern-axis?
Must be standing square
What is a broken back HPA?
When the angle of P2 is greater than the distal Phalynx
What structures are overloaded when you have a broken back HPA?
DDFT, Navicular bone, P2 and P1
How can you correctively shoe a broken back HPA?
Wedge 2-10 degree (get to any more is impovement
What is broken forward HPA
When the angle of P2 is less than that of the hoof wall
-Club foot, flexural limb deformity
What does broken forward HPA predispose the horse to?
Stain suspensory, sole bruising, stretched white line, abscesses
