Laminitis is an inflammation of the sensitive laminae of one or more hooves. Severe pain can result from poor circulatory congestion in the foot. When the sensitive laminae become inflamed, the union between the hoof and the laminae can separate. In severe cases the coffin bone can rotate and begin to penetrate the sole.
A foundered horse often has a distorted hoof with characteristic "founder rings," a long toe that curls if neglected. There are many treatments for founder, but prognosis is guarded, depending on extent of the condition.
