What is it?
Laminitis is the result of a disruption of blood flow to the sensitive and insensitive laminae of the equine hoof. Whether the disruption of blood flow is intermittent, constant, or short term, there is a painful inflammatory response that can affect any or all of the hooves, but most commonly the front feet.
The laminae attach the coffin bone to the hoof wall. As inflammation occurs, there is a painful separation that begins between these two structures. These changes result in abnormal hoof growth, lameness, and (if severe) can progress to coffin bone rotation or sinking through the sole.
The term "founder" is often used interchangeably with laminitis.

How is laminitis treated?
The sooner action is taken to stop the insult, the better the prognosis and recovery. The ultimate goal is to relieve pain and get the hooves to a functionally normal state. Each laminitic case is unique to that horse and your veterinarian can diagnose and develop a treatment plan best suited for your horse. Key steps may include:
What is the prognosis?
The prognosis for laminitis varies. Radiographs are essential in determining the degree of rotation of the coffin bone as it loses structural support from the laminae on the wall. Once a laminitis event occurs, the horse is prone to future episodes, therefore prophylactic management measures are highly recommended. These include diet changes, regular hoof maintenance and routine health monitoring. The sooner laminitis is diagnosed and treated, the better the long term prognosis.
