How Do You Know If Your Horse Has A Coffin Bone Rotation?

Diagnosis can be confirmed through radiographs (X-rays), which can show sinking or rotation of the coffin bone within the hoof capsule, as well as thickness of the sole and more chronic bone changes.

Can a horse recover from a rotated coffin bone?

Although significant rotation has been associated with a poorer prognosis, there is evidence of horses with rotation of up to 30° being corrected. However, if there is significant rotation of the pedal bone and treatment is not instigated, the disease can progress.

What happens when coffin bone rotates?

As the coffin bone rotates downward, it presses the sole of the hoof, causing severe lameness. In severe cases, the tip of the coffin bone can penetrate the sole of the hoof.

What is a rotated coffin bone?

The term “Rotation” has commonly been used when the dorsal surface of the coffin bone stretches or separates its distal (bottom) attachment from the hoof capsule and appears to rotate downward. (Figure 1) As a rule, the coffin bone maintains its general position relative to the ground.

What does a coffin bone look like?

It is a unique bone as it is triangular in shape when viewed from the side, and semi-circular when viewed from the top. It is significantly lighter in weight, than the other bones in the hoof due to it having many holes in it which allow the vast network of blood vessels to run through it.

What causes a horses coffin bone to rotate?

The combination of tension of the flexor tendons and weakened laminae can cause rotation of the coffin bone.

How do you reverse a coffin bone sinking?

Repeat trims often enough to keep the hoof walls out of a primary weight-bearing situation so that they can settle into a more natural position (relative to the coffin bone) over time. This is a typical trim I use to reverse (and prevent) coffin bone sinking.

How do you tell if a horse has foundered in the past?

Observant horse people recognize the appearance of a “foundered hoof”. These feet typically show several signs in combination: a dished dorsal hoof wall, dropped or flat sole, a widened white line and obvious growth rings or lines on the hoof wall. These lines are usually spaced wider apart at the heel.

When is it time to put a laminitic horse down?

The horse is unlikely to die from laminitis, but an owner may take the decision to euthanase their animal if the pedal bone penetrate the sole so that the outlook is very poor or if their animal does not respond to appropriate treatment over a prolonged period.

What are the first signs of laminitis?

SIGNS

• Lameness, especially when a horse is turning in circles; shifting lameness when standing.
• Heat in the feet.
• Increased digital pulse in the feet (most easily palpable over either sesamoid bone at the level of the fetlock).
• Pain in the toe region when pressure is applied with hoof testers.

How long does it take for a horse to founder?

You can founder a horse by putting them on an insulin drip for 48 hours, or simply by turning them out onto the equine version of a Snicker’s bar — a green spring pasture. The high sugar content of the grass signals the body to produce even more insulin. Take a look around the dry lot.

When can I turn my horse out after laminitis?

The standard advice is 30 days of box rest after the horse or pony is moving around the stable freely, but this may vary depending on the affected animal’s condition. Some horses that founder may have to be stabled for up to a year after the initial bout of laminitis.

Can you ride a horse with mild laminitis?

Even just one episode of laminitis that is not treated properly can lead to permanent changes to the hoof. Your horse may never be able to be ridden again, or may need to be euthanased. This is why you must be aware of the signs of the disease and always call a vet if you suspect even just a mild episode.

Does cold hosing help laminitis?

Horse owners should not be tempted to stand horses or ponies suffering from laminitis in a stream or to cold hose their hooves. Although it may initially make the animal more comfortable, prolonged cold will make the condition worse.

Where is the coffin bone in a horse located?

hoof
The coffin bone, also known as the pedal bone or the distal phalanx, is the bottommost bone within a horse’s leg, similar to the tip of a human finger. Although uncommon, coffin bone injuries are both serious and dangerous as the hoof capsule is shaped around this particular bone.

How do you prevent a horse from foundering?

To avoid grass founder:

1. Allow the horse to fill up on hay before turning out on grass for a few hours.
2. Place a grazing muzzle on horses predisposed to foundering to limit their forage intake. Grazing muzzles limit grass intake but allow the horse to exercise throughout the day.

What bone rotates in laminitis?

Laminitis means inflammation (‘itis’) of the laminae which form the junction between the hoof wall on the outside and the foot including the pedal bone on the inside. The resulting laminar destabilisation may result in rotation or sinking (founder) of the pedal bone inside the hoof capsule.

Can the founder be reversed?

Yes, most horses will recover completely from founder if it is caught and addressed early. There are cases, however, where changes in the foot will result in life-long lameness.

What are signs of neurological problems in horses?

Lack of coordination, weakness or paralysis of the hind limbs, muscle twitching, impaired vision, head pressing, aimless wandering, convulsions, circling and coma are some of the severe neurologic effects. Horses typically have non-neurologic signs, too, such loss of appetite and a depressed attitude.

Why do horses get laminitis after surgery?

One major theory is vascular leakage and secondary swelling within the hoof capsule. Swelling and hoof rotation impair blood flow, leading to more damage via compartment syndrome effects. Other theories to explain laminitis include poor blood flow, vascular thrombosis, and abnormal keratinization.

How long does it take for a coffin bone to heal?

As a porous bone, this injury generally heals after 12 weeks of treatment. The most important element when treating a coffin bone injury is to deter movement of the hoof wall.
