Does Laminitis in Horses Have a Cure?

The difference between a laminitis episode that ends up being an anecdote and a laminitis that becomes a chronic problem may, in many cases, lie in how quickly it is identified and intervened.

The first signs can be subtle: changes in mobility, sensitivity when walking, increased hoof temperature, more marked digital pulse, changes in posture, or slight resistance to movement.

Waiting for the horse to show intense lameness can mean that the process has already advanced.

The earlier laminitis is detected, the sooner intervention can be made and the greater the possibility of limiting structural damage. Therefore, before any suspicion of laminitis, it is essential to carry out an immediate veterinary evaluation, complemented when necessary with imaging tests such as radiographs and a detailed assessment of hoof balance and structures.

Laminitis is a disease in which the laminar structure that keeps the third phalanx (P3) suspended inside the hoof capsule is altered. Anything ending in -itis means inflammation. When the inflammatory and vascular process progresses, the structures that connect the bone to the hoof wall (laminae) can suffer significant damage.

The longer the process remains active, the more compromised the blood circulation in the hoof can become. This is especially important in the solar corium, the tissue responsible for producing the sole.

When blood perfusion of the solar corium is compromised for too long, the tissue can suffer ischemia, tissue damage, and even necrosis. As a result, the ability to produce new sole decreases considerably.

This can create a vicious circle: less circulation → less sole production → less protection between P3 and the ground → more pressure on the solar corium → more tissue damage.

One of the most serious problems in certain cases of chronic laminitis is the progressive loss of sole thickness.

The third phalanx remains under significant load inside the hoof. If the sole cannot grow fast enough and the tissue that produces it is compromised by poor blood perfusion, the sole thickness can progressively decrease.

As this protection is lost, P3 gets closer and closer to the ground, increasing the pressure exerted on the solar corium.

For this reason, in advanced cases of laminitis, it is not only important to control pain and inflammation: it is also essential to protect the internal structures of the hoof and promote conditions that allow sole growth to recover.

As the disease progresses, the third phalanx can undergo important structural changes. The alteration of circulation and the loss of protective tissue around P3 can favor bone remodeling processes. In the most severe cases, the bone can suffer progressive deterioration associated with vascular compromise and loss of protection from surrounding tissues, such as the sole.

Therefore, chronic laminitis should not be considered simply as inflammation that lasts longer. In advanced cases, it can become a structural disease of the hoof, in which damage has occurred that needs time to heal and that, in some cases, may be irreversible.

The laminae of the hoof play a fundamental role in suspending P3 inside the horn capsule. During laminitis, this connection can progressively deteriorate.

When the laminae lose their integrity and their ability to keep the third phalanx properly suspended, the stability of the entire system is compromised. In addition, the vascular damage associated with the process can affect the viability of these tissues.

In severe cases, this loss of support can favor the displacement of P3 inside the hoof capsule, leading to changes such as rotation or sinking of the third phalanx.
