What is it? The hoof wall is made up of an interlocked outer layer that is insensitive this is called the horn and is supported by an underlying inner area that is sensitive this is called the Laminae. When Laminitis occurs the blood flow to the laminae is affected, this causes inflammation and swelling in the tissues that are with in the hoof, it also causes extreme amounts of pain. The Laminae doesn't get any oxyden or nutrient rich blood causing the cells to become damaged. If the cause is removed and treatments is started as soon as the first sign of the condition shows, the laminae stays alive, however if it is left untreated it will begin to die. The Laminae supports the pedal bone (this is in the hoof) and the weight of the animal. In extremely severe cases of laminitis the pedal bone can sink and rotate, because the Laminae can't support it also from the pull og the deep digital flexor tendon.If the pedal bone sinks too far it can come through the sole of the foot. ...
