Reading a Hoof

Learning how to 'read' a hoof is a useful skill. These are the severely compromised hooves of a 9 year old 15.2 hh thoroughbred.



 Left fore                    


Long toe;  long walls; stretched white line; long collapsed and contracted heels and bars; bars laying over and fused with sole; flared quarters, worse laterally; very little concavity; thin sole; frog load bearing along inner third; bulbs compressed; central frog sulcus a shallow cleft; no structure to digital cushion. 



                                               










Right Fore 



Medial heel contracted and medial side of P3 narrowed as result; lateral heel much longer, grossly flared and under run; bone loss along distal margins laterally and at medial toe; lateral bar long and fused completely with sole; medial bar wedged under frog; sole corium in medial heel/bar triangle deformed by inward turning heel, in lateral HBT subjected to persistent ground pressure transmitted by overlaid bar and heel horn; rearward third of frog and bulb folded inwards; medial lateral cartilage deformed inwards, lateral pulled under by collapsed under run heel; degenerated digital cushion.








Left hind




Long toe; long, collapsed heels and bars; vertically compressed bulbs and frog sulcus a cleft turned in on itself; weak DC; thin walls. This was the horse's least deformed hoof.













Right hind


Long toe; rotated pedal bone (broken forward HPA); severely contracted medial heel; thin walls, heels and bars; medial bar pushed up and wedged under frog; lateral heel forward and long; gross flare to quarter; bone loss; quarter crack; frog folded in on itself and collapsed forward. (I had already removed a section of medial wall and exposed the frog apex before these shots were taken and sadly there are no lateral or dorsal views of the hinds.)
