Lecture 4: Foot Pathologies
From the Sole:
Sole Bruise
- Most common cause of lameness
- Sudden onset of mild to severe lameness
- Some horses bruise more easily than others, but all horses can have them
- Can be very painful but typically transient (only longer term lameness if the bruise
develops into an abscess
- Causation:
oHave some kind of concussive force on the foot which damages internal tissues
and ruptures blood vessels
oRocky ground
oShoes
Not removed when they should have been
Wrongly shoed
oResult of disease
Like laminitis which is internal pressure pushing on the sole of the foot
Corn
- Bruise occurring at the “seat of corn”
- More likely from loose or too thin/small of shoes
Hoof Abscess
- Sometimes bruises can become abscesses
- Internal infection of foot that is accompanied by inflammation
- Pain and damage exacerbated because horse bears weight continuously on affected
area and abscess swelling is confined by solid hoof wall
- Causation:
oBruise
oSole puncture
Can be very small so sometimes hard to identify or locate
oWhite line disease
- Pathology:
oDebris invades foot (this migration into the foot enhanced by weight bearing
because on continuous contraction and expansion of the hooves)
oInflammation occurs
oPressure is increased around surrounding tissues
oThis causes lameness, enzymatic tissue destruction
this will allow inflammation to grow and spread
if enough grow and spread it can penetrate boney tissue
oinfection moves through the tissues

Document Summary
Some horses bruise more easily than others, but all horses can have them. Can be very painful but typically transient (only longer term lameness if the bruise develops into an abscess. Causation: have some kind of concussive force on the foot which damages internal tissues and ruptures blood vessels, rocky ground, shoes. Not removed when they should have been. Like laminitis which is internal pressure pushing on the sole of the foot. More likely from loose or too thin/small of shoes. Internal infection of foot that is accompanied by inflammation. Pain and damage exacerbated because horse bears weight continuously on affected area and abscess swelling is confined by solid hoof wall. Can be very small so sometimes hard to identify or locate: white line disease. White line disease localized to the toe this can be a problem with shoes, as it can develop and not be detected ( to avoid this keep feet care frequent.
