Pathology & Reason Flashcards
Dropped Sole
Extremely flared, genetically inclined or neglected feet. Founder. Sinker
Hoof Avulsion
Mechanical force. Bad hoof infection. Founder. Extreme WLD (White Line Disease).
Cracks
Drastic moisture changes. Uneven weight bearing. Coronary band injury. Weak hooves.
Corns
Pressure on the seat of corn. Short/tight shoeing. Going too long before resetting.
Canker
Unknown/debatable. Some breeds are more susceptible.
Club Foot
Open to conjecture. Genetics. Gazing stance. Feed induced. Injury.
Founder
Failed laminar bond. Separating force of weight bearing & DDFT (Deep Flexor Tendon) pull on P3. Upward pressure on toe wall.
Abcess
Bacterial penetration of the sensitive tissue. Puncture wound, bruising, sole pressure, cracks.
Laminitis
Over feeding carbohydrates, retained placenta, genetic predisposition, insulin resistance.
P3 Fracture
Trauma, ie., concussion, pedal osteitis or bone cysts causing bone weakness. Torque on the bone.
Soft Heel Cracks
Sheared heels, weak heels, or deep central sulcus may predispose horses to this problem.
Navicular
Concussion related: Steep HPA. Suspensory related: Shallow HPA, long toe & continuous tension on DDFT.
Quittor
Caused by anything that allows infection of the lateral cartilages. Gravitating abscess or direct injury.
Keratoma
Continuous irritation to the hoof from injury. Excess keratinization.
Sole Bruises
Hard riding on rough terrain and shoeing with sole pressure are common causes.
Pedal Osteitis
Lack of blood supply. Concussion. Sole Pressure. Chronic bruising.
Sheared Heels
Hoof imbalance, as a result of bad trim or conformational deviations.
Quarter Cracks
Unbalanced trim. Proximal coronary band displacement. Weakness as a result of injury to the coronary band.
Sidebone
Hard footing/concussion. Mediolateral imbalances. Deep cut involving the lateral cartilage.
White Line Disease (WLD)
Opportunistic bacteria/fungus entering via separation of the sole/wall junction. Some horses are more predisposed to infection.
Thrush
Neglect and damp, unsanitary conditions. Anaerobic bacteria damages the frog tissue.
