Acute laminitis, or founder, is a serious condition that affects the tissues (laminae) that connect the hoof wall to the coffin bone in a horse’s foot. When these laminae become inflamed and damaged, it can cause severe pain and lameness. If not managed promptly and effectively, acute laminitis can lead to a range of complications, some of which can be life-threatening.
What Are the Potential Complications of Acute Laminitis?
Coffin Bone Rotation and Sinking?
One of the most significant complications of laminitis is the rotation or sinking of the coffin bone within the hoof capsule. As the laminae weaken, they can no longer support the coffin bone properly, leading it to rotate downwards or sink. This can cause the bone to press against the sole of the foot, resulting in intense pain and potential penetration of the sole.
Chronic Laminitis and Founder?
Acute laminitis can develop into chronic laminitis, a long-term condition characterized by persistent inflammation and damage to the laminae. Chronic laminitis often leads to founder, a permanent and often debilitating condition that can severely impact a horse’s quality of life.
Abscess Formation?
The inflammation and damage associated with laminitis can increase the risk of abscess formation within the hoof. Abscesses are pockets of infection that can cause significant pain and lameness. They often require veterinary intervention to drain and treat.
Hoof Wall Deformities?
Chronic laminitis can cause visible deformities in the hoof wall. These deformities may include uneven hoof growth, the formation of "founder rings" (horizontal ridges on the hoof wall), and a dished or concave appearance to the hoof. Such deformities can further compromise the structural integrity of the hoof and increase the risk of further complications.
Sole Penetration?
In severe cases of laminitis, the coffin bone may rotate or sink to such an extent that it penetrates the sole of the foot. Sole penetration is a painful and serious complication that requires immediate veterinary attention. It can lead to severe infection and may necessitate euthanasia in some cases.
Reduced Performance and Quality of Life?
Even with treatment, horses that have experienced acute laminitis may suffer from reduced performance and a diminished quality of life. Chronic pain, lameness, and hoof deformities can make it difficult for horses to engage in athletic activities or even move comfortably.

How Quickly Can Laminitis Progress?
Laminitis can progress rapidly, sometimes within a matter of hours. The acute phase, characterized by intense pain and inflammation, requires immediate veterinary intervention to prevent further damage.
What Are the Early Signs of Laminitis?
Early signs of laminitis can be subtle but may include:
- Increased digital pulse in the foot
- Heat in the hooves
- Tenderness or pain when pressure is applied to the sole of the foot
- A "pottery stance," where the horse shifts weight between feet to relieve pain
Can Laminitis Be Prevented?
While not all cases of laminitis are preventable, there are steps that owners can take to reduce the risk. These include:
- Maintaining a healthy weight
- Avoiding sudden changes in diet
- Limiting access to lush pastures, especially for horses prone to laminitis
- Providing regular exercise
- Ensuring proper hoof care
Understanding the potential complications associated with acute laminitis is crucial for horse owners. Early recognition, prompt veterinary intervention, and diligent management are essential to minimize the risk of long-term damage and improve the horse’s chances of recovery.
