Laminitis is an inflammation and damage to the laminae within a horse’s hoof, often stemming from issues like poor diet or obesity. This condition causes severe pain and can be fatal, significantly affecting a horse’s ability to walk.
How Does Laminitis Affect a Horse’s Gait?
Laminitis primarily affects a horse’s ability to walk by causing intense pain and structural damage within the hoof. The laminae are the interlocking tissues that suspend the coffin bone (the last bone in the leg) within the hoof wall. When these laminae become inflamed and damaged, the connection between the coffin bone and the hoof wall weakens.
What Happens to the Coffin Bone During Laminitis?
During laminitis, the inflammation and damage to the laminae can lead to several detrimental changes:
- Rotation: The weakened laminae may no longer be able to support the coffin bone against the pull of the deep digital flexor tendon, causing the bone to rotate within the hoof.
- Sinking: In severe cases, the coffin bone can sink within the hoof capsule as the laminae fail completely.
- Pain: The inflammation and pressure on the damaged laminae cause extreme pain, making it difficult and painful for the horse to bear weight on the affected hoof.
How Does Pain Impact a Horse’s Movement?
The pain associated with laminitis leads to noticeable changes in a horse’s movement:
- Reluctance to Move: Horses with laminitis are often reluctant to move or put weight on the affected feet.
- Stilted Gait: When they do move, they may exhibit a stilted, choppy gait, trying to minimize the pressure on the painful areas.
- Shifting Weight: Horses often shift their weight from foot to foot to find a more comfortable position, which can be observed as a rocking motion.
What Are the Long-Term Consequences of Laminitis?
If laminitis becomes chronic, it can lead to long-term complications that further impair a horse’s ability to walk:
- Hoof Wall Deformities: Chronic inflammation and instability can cause permanent deformities in the hoof wall.
- Abscesses: Damage to the laminae can lead to abscess formation within the hoof.
- Permanent Lameness: In severe cases, the structural damage is irreversible, resulting in chronic lameness.

How is laminitis diagnosed in horses?
Laminitis is diagnosed through a combination of physical examination, hoof radiographs (X-rays), and clinical history. Veterinarians assess the horse’s gait, check for heat and pain in the hooves, and use radiographs to evaluate the position and integrity of the coffin bone within the hoof capsule.
What are the early signs of laminitis?
Early signs of laminitis include increased digital pulse in the lower leg, heat in the hooves, reluctance to turn, and a characteristic "laminitic stance" where the horse shifts weight to the hind legs to relieve pressure on the front feet. Recognizing these signs early is crucial for prompt treatment.
Can laminitis be prevented?
Yes, laminitis can often be prevented through careful management practices. Key preventive measures include maintaining a balanced diet, avoiding overfeeding of carbohydrates, ensuring regular exercise, and providing proper hoof care. Monitoring horses at risk, such as those with obesity or metabolic disorders, is also essential.
What treatments are available for laminitis?
Treatment for laminitis focuses on reducing inflammation, alleviating pain, and stabilizing the coffin bone within the hoof. Common treatments include anti-inflammatory medications, pain relievers, therapeutic shoeing to support the hoof, and strict dietary management to address underlying metabolic issues.
Laminitis profoundly affects a horse’s ability to walk by causing pain, inflammation, and structural damage within the hoof. Early recognition and appropriate management are essential to minimize long-term consequences and improve the horse’s quality of life.
