Laminitis, also known as founder, is a painful condition in animals, especially horses, characterized by the inflammation and damage to the laminae, which connect the hoof to the coffin bone. This inflammation can lead to severe pain and lameness, and in critical situations, the separation of the laminae can cause the coffin bone to sink within the hoof.
What is the Role of Inflammation in Laminitis?
Inflammation is central to the development and progression of laminitis. The laminae are soft tissue structures inside the hoof that attach the coffin bone to the hoof wall. When these laminae become inflamed, their structural integrity is compromised, leading to a cascade of events that can result in laminitis.
How Does Inflammation Start in Laminitis?
The causes of laminitis are varied, but they often lead to a common inflammatory pathway. Some potential causes include:
- Dietary Overload: Excessive consumption of carbohydrates or lush pastures can trigger an inflammatory response.
- Obesity: Overweight horses are more prone to metabolic issues that promote inflammation.
- Systemic Diseases: Infections or other illnesses can release inflammatory mediators into the bloodstream, affecting the hooves.
What Happens During the Inflammatory Process?
Once inflammation begins, several events occur:
- Vasodilation: Blood vessels in the laminae dilate, increasing blood flow to the area.
- Edema: Fluid leaks from the blood vessels into the surrounding tissues, causing swelling.
- Cellular Damage: Inflammatory cells release enzymes and toxins that damage the laminae.
- Laminar Separation: The connection between the laminae weakens, potentially leading to separation of the hoof wall from the coffin bone.
What Are the Consequences of Inflammation in the Hoof?
The ongoing inflammation and damage in the laminae can lead to:
- Pain and Lameness: Horses exhibit signs of discomfort, reluctance to move, and a characteristic stance of shifting weight between their front feet.
- Hoof Deformity: Chronic laminitis can cause the coffin bone to rotate or sink within the hoof, resulting in visible changes to the hoof’s shape.
- Founder: In severe cases, the coffin bone can penetrate the sole of the hoof, a condition known as founder.

How is laminitis diagnosed?
Diagnosis typically involves a physical examination, assessment of lameness, and imaging techniques such as radiographs (X-rays) to evaluate the position of the coffin bone within the hoof. Veterinarians also consider the horse’s history and potential underlying causes.
What are the treatment options for laminitis?
Treatment focuses on reducing inflammation, managing pain, and supporting the hoof structure. This may include anti-inflammatory medications, therapeutic shoeing, dietary changes, and addressing any underlying metabolic or systemic issues.
Can laminitis be prevented?
Prevention strategies include maintaining a balanced diet, avoiding sudden changes in feed, managing weight, providing regular exercise, and promptly addressing any underlying health problems. Regular hoof care and monitoring can also help detect early signs of laminitis.
Inflammation plays a pivotal role in the development and progression of laminitis, affecting the integrity of the laminae and leading to pain, lameness, and potential hoof deformity. Understanding the inflammatory processes involved is crucial for effective management and prevention of this debilitating condition.
