horizontal hoof crack

no lameness
seldom increase in size
can predispose to vertical cracks
vertical hoof crack

ground origin = grass cracks
sand cracks etiology
- Injury to the coronary band

- ML or diagonal imbalance – displaced coronet
sand cracks treatment

- Pulsation of digital arteries
- Warmer hoof capsule (localized or not)

- Corrective trimming and shoeing
tumour of hoof
keratoma
signs of keratoma
progressively more serious lameness
diagnosis of keratoma
hoof tester
DA
xray
treatment of keratoma
surgical removal of tumor
hoof, pressure bandage
