A penetrating hoofinjury in the region of the sole caused by the horse treading on the clip of the horseshoe after the horseshoe has been partially or completely pulled off.

Physical damage to any anatomical structure with or without loss of tissue.

A penetrating injury of the hoof through a foreign body such as a nail, a screw or a wire. The injury may be anywhere within the hoof capsule although the frog and the clefts of the frog are particularly at risk. The object may penetrate and cause injury to underlying structures such as the corium or even deeper structures such as the coffin bone, the deep digital flexor tendon or the navicular bursa.

A wound anywhere on the coronary band, most frequently caused by interference with other limbs: A typical cause is an overreach injury where a  hind foot catches and injures the coronary band or heel bulbs in the palmar region of the fore foot. Injury of the medial portion of the coronary band can be caused by a contralaterallimb, and injury to the lateral portion of the coronary band is most often a result of interaction with another horse. Other causes of injury to the coronary band include knuckling over or hitting the region on a solid object such as a jump.

An injury to the bulbs of the heel, generally caused by an overreach injury (the toe of a hindlimb injures the bulb of the ipsilateralforelimb).

An injury caused by a horse tripping and falling onto its knees. It is a type of injury which may happen repeatedly and can leave typical scars (hairless patches and calluses). This type of injury may be the result of a horse being shod with excessively long toes, or any orthopaedic disorder which leads to a reduced arc of flight and predisposes to the hoof catching on the ground during the swing phase .
