equine orthoapedics of the foot Flashcards
how do hoof cracks occur and what direction do they usually run in
can be caused due to poor foot balance, poor horn quality or trauma.
can be incomplete or complete and they often run in a proximo-distal direction
how does a hoof crack progress
instability leads to shear forces, further seperation, infection and pain
how are hoof cracks treated
if incomplete only functional trimming is needed. filler can be used to fill in the crack or wires and bar shoes can also be used
define white line disease
progressive, crumbling, poor quality hoof wall with seperation at the white line
clinical signs of white line disease
lameness possible.
seperation of hoof wall especially at toes with grey crumbly horn seen
what is seen with injuries to the coronary band and hoof wall
haemorrhage!
moderate to severe lameness
possible involvement of joint/tendons
when treating a coronary band and hoof wall injury which structure should you aim to preserve
the coronary band!
consider use of bandages and casts
whats the difference between a nail bind and a shoeing prick
nail bind: nail is close to sensitive structures. mild lamesness. pain around nail
shoeing prick: nail into sensitive structures. immediate pain. develop into subsolar abscess if untreated
subsolar abscessation clinical signs
ACUTE onset
increased digital pulse
increase hoof temperature
sensitive to hoof testers
cause and treatment of subsolar abscessation
penetration of bacteria leads to abscess formation which puts pressure on sensitive lamina
follow tracts and remove any necrotic/underrun horn
apply poultice daily after
in cases of foot penetration involving synovial structures. where on the hoof are you likely to find the foreign body
middle third
what are possible causes for chronic hoof abscessation
keratoma
sequestrum
pedal osteitis
laminitis
what is a keratoma
bening tumor of the hoof and solar horn
clinical signs of keratoma
intermittent lameness and discharge.
characteristic circular abnormal area of keratinisation seen.
smooth radiolucent defect seen in p3 on xray
what is quittor
infection of the collateral cartilages
