A ‘corn’ is '''bruising''' of the sole in the ‘'''seat of corn'''’ (the angle between the medial hoof wall and the bar of the hoof). The most common location for this bruising is the '''medial''' side of the '''fore feet'''.

==Clinical Signs==

==Clinical Signs==

The bruising may be '''visible''' on the sole after '''paring down''' the hoof. It normally occurs on the medial side of the fore feet. The horse will normally test positive to '''hoof testers''' over this region. The horse will normally present with a '''low-grade lameness'''. Lameness will be more severe when loading of the bruised area is greatest and, in the case of the medial side, this will be when the affected limb is on the outside of the circle.

#The '''shoe''' should be '''removed''' and the sole of the hoof '''pared out''' to reveal the bruising.

The '''shoe''' should be '''removed''' and the sole of the hoof '''pared out''' to reveal the bruising. If infection has developed then paring should continue to allow '''draining''' of the purulent material. The '''shoe''' should be left '''off''' for several days to allow the bruising to heal. It can be '''re-applied''' when the horse is '''sound'''.

To avoid the recurrence of the corn, pressure should be avoided over the region. For example, the caudal end of the medial branch of the shoe can be seated out, in addition the heel can be widened so it covers and protects the affected area.
