This condition, also known as founder, has affected horses for hundred of years, yet in recent years we are beginning to uncover the mechanics, physiology and best treatment of this condition.

Laminitis is defined as the inflammation of the juncture of the hoof wall lamina and the bone lamina, in other words the attachment of the bone to the hoof. As this condition sets in the horse experiences some degree of pain, from minor to severe. If the condition continues unabated, the hoof begins to separate form the bone due to secretion of enzymes that cause the membrane that holds the hoof and bone together to literally dissolve. Untreated cases can then progress to penetration of the coffin bone,( the bone in the foot), thru the bottom of the foot.

What will cause the activation of such a devastating phenomena could only be contained in a long and growing list. A few of the most common are, large consumption of feed at one time, heavy grazing on a new succulent pasture, some medications, severe colic, stresses of general surgery, hard riding in hot weather, severe dehydration, to name only a few. Just how each of these ignite this response, still have many research investigations continuing at several universities.

Treatment can be very challenging as the main goal is to support the foot, prevent distortion of blood supply and provide pain control. Support is achieved by applying mechanical devices to the foot to provide sole pressure without invading the point of toe breakover. A cushioning compound is placed between the sole and the device to not only provide support but comfort for the horse. Additional assistance for the patient is to allow soft terrain to walk on for more comfort. Pain medication is given when needed.

Continuing treatment involves x-rays to determine the position of the coffin bone in the foot. If any changes are noted, the angle of the bone must be adjusted to provide a proper growth pattern and comfort for the patient. As the foot becomes more stable changes are made in the position and type of support devices that need to be used.

Because this is a long process, treatments may require as long as 6 months to a year to return the patient to normal or to a usable condition. Some of these cases require time and labor intensive care; others require a substantial dollar investment.

Although laminitis can be managed in many cases and reap a desirable response, others are not that lucky. Early detection and care result in the best result and usually shortest treatment.
