Laminitis is a painful condition that affects the hooves of animals like horses, often due to inflammation and damage. Diagnosing it involves a comprehensive approach, combining physical exams with diagnostic tests to pinpoint the underlying cause and severity. Early and accurate diagnosis is key to managing the condition and preventing long-term complications.
How Do Vets Diagnose Laminitis in Horses?
Veterinarians use a combination of methods to diagnose laminitis in horses, including physical examinations, diagnostic imaging, and laboratory tests.
Physical Examination
A thorough physical exam is the first step in diagnosing laminitis. Vets will look for key signs, such as:
- Increased digital pulse: A stronger pulse in the digital arteries of the lower leg can indicate inflammation in the hoof.
- Hoof temperature: Elevated temperature in the hoof can also signal inflammation.
- Pain response: Horses with laminitis typically show a pain response when pressure is applied to the sole of the hoof.
- Stance and gait: Affected horses may adopt a characteristic stance, shifting weight between legs or leaning back to alleviate pressure on the toes. Their gait may appear stiff or hesitant.
Diagnostic Imaging
Imaging techniques help vets visualize the internal structures of the hoof and identify changes associated with laminitis:
- Radiography (X-rays): Radiographs can reveal rotation or sinking of the coffin bone, a key indicator of laminitis. They also help assess the severity of the condition and monitor changes over time.
- Venography: This technique involves injecting a contrast dye into the blood vessels of the hoof and taking X-rays. It can help assess blood flow and identify areas of inflammation or damage.
Laboratory Tests
While physical exams and imaging are central to diagnosing laminitis, lab tests can help identify underlying causes or contributing factors:
- Blood tests: Blood samples can be analyzed to detect metabolic disorders like equine metabolic syndrome (EMS) or Cushing’s disease, which are often associated with laminitis.
- Endocrine testing: Vets may also perform specific endocrine tests to assess hormone levels and identify hormonal imbalances that could be contributing to the condition.

What are the early signs of laminitis in horses?
Early signs can be subtle but may include increased digital pulse, warm hooves, reluctance to turn, and a shifting of weight between feet. Recognizing these early indicators is crucial for prompt intervention.
Can laminitis be cured in horses?
While there’s no definitive cure for laminitis, it can be effectively managed with prompt and comprehensive treatment. This includes addressing the underlying cause, providing pain relief, and supporting the hoof structure.
How can I prevent laminitis in my horse?
Prevention strategies include maintaining a healthy weight, limiting access to lush pastures (especially for horses prone to metabolic issues), providing a balanced diet, and ensuring regular exercise. Routine hoof care and early intervention for any signs of foot discomfort are also essential.
By combining these diagnostic approaches, veterinarians can accurately diagnose laminitis, determine its severity, and develop a targeted treatment plan to improve the horse’s comfort and long-term prognosis.
