What is a coffin bone fracture?

Fractures of the coffin bone or distal phalanx usually occur in the horse following some type of trauma, often from kicking, or a large force placed on the coffin bone (i.e., racing on hard tracks).

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

These tools help determine the location and severity of the fracture, so hoof-care professionals can establish a proper treatment plan. 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.

Can a horse recover from a broken coffin bone?

Horses might require a full year out of work to recover completely from some coffin bone fractures. Any return to work after injuries and layoffs should be very gradual, and the horse should be monitored closely for any sign of pain or lameness.

Can a horse recover from a fractured fetlock?

The outlook for recovery is fairly good if small fragments are surgically removed as soon as possible. Many of these horses can return to racing. Horses with a fracture in a hindlimb respond more favorably than those with a fracture in the forelimb.

Why is it called coffin bone?

The coffin bone meets the short pastern bone or second phalanx at the coffin joint. The “coffin bone” gets its name because it is encased in the hoof like a corpse in a casket.

Where is the coffin joint?

The coffin joint is situated between the pedal bone and pastern bone and is often successfully treated with joint medication and remedial farriery. The coffin joint communicates directly with the navicular bone and the tendons inside the hoof capsule.

What causes coffin rotation?

Takeaways. Laminitis is inflammation and damage of the tissue between the hoof and the underlying coffin bone. In severe cases, it can progress to founder, in which the hoof and coffin bone are separated and the coffin bone can rotate, leading to severe pain.

How do horses break their coffin bone?

Can coffin bone rotation be corrected?

Q. Can rotation always be corrected? A. In most cases rotation can and should be corrected at the earliest opportunity, it’s a case of trimming the hoof capsule back in alignment with the pedal bone.

Do horses have to be euthanized after breaking a leg?

Compound fractures, where a broken bone penetrates the skin, have a much poorer prognosis and are less likely to heal successfully without complication. Such cases are likely to be euthanized, particularly if the blood supply to the leg has been compromised.

What type of bone is the coffin bone?

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.

What is the coffin joint?

The coffin joint lies between the second and third phalanges of each limb. The joint space is located under the interface of the hoof and haired skin on the limb (coronet band). Horses with coffin joint pain present with a wide range of symptoms: from acute lameness to poor athletic performance.

Which bone is the coffin bone?

distal phalanx
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.

Can you fix a rotated coffin bone?

Can rotation always be corrected? A. In most cases rotation can and should be corrected at the earliest opportunity, it’s a case of trimming the hoof capsule back in alignment with the pedal bone.

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 coffin bone in a horse?

What causes a rotated coffin bone?

Laminitis is inflammation and damage of the tissue between the hoof and the underlying coffin bone. In severe cases, it can progress to founder, in which the hoof and coffin bone are separated and the coffin bone can rotate, leading to severe pain.

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.

It is completely encompassed by the hoof wall, and is where the horse’s body weight rests as a pressure-force before it is transferred to the hoof plate. Coffin bone fractures can occur a number of ways, some of the most common being:

What happens if a horse has a fracture in its coffin?

Extensor process and solar margin fractures usually result in slight lameness (grade 1-2 of 5), where center and wing fractures tend to cause moderate to severe lameness (grade 4-5 of 5). Since the coffin bone is completely enclosed within the hoof capsule, there will not be any swelling or pain on palpation.

What are the treatment options for a fractured coffin bone?

Although not among the more common therapies, the following are also possible options to treat a fractured coffin bone: · Surgery involving the placement of a permanent screw in the bone can be useful for types 2, 3, 4 and sometimes 5 fractures.

What supports the coffin bone on a horse?

The laminae and digital cushion support and protect the pedal bone. There are many tendons/ligaments attaching to the coffin bone (particularly in the back of the hoof), as well as a network of blood vessels surrounding it. Within this support structure, you also find the navicular bone nestled in the back of the pedal bone.
