Where Are Coffin Joints On A Horse?
The most distal bone in the horse’s leg is the coffin bone. The coffin bone is the hoof shaped bone that attaches to the laminae in the hoof. The coffin joint is the intersection between the coffin bone and the next bone up, the short pastern bone.
How many coffin joints does a horse have?
The three bones are the coffin (aka “pedal”) bone, the pastern bone, and the navicular bone. The coffin bone essentially equates in humans to the last bone on a person’s middle finger.
What causes inflammation in the coffin joint?
This degenerative process is seen as a consequence of traumatic injury, including coffin bone fractures and chronic stress and wear, especially in horses with poor lower limb conformation. It is more common in heavy breeds and those that heavily impact the forelimbs in their work, such as jumpers.
What does coffin joint mean?

What is another name for the coffin joint?

The coffin bone, also known as the pedal bone or distal phalanx, is a small bone within the horse’s hoof. It is the anatomic equivalent of the bone that forms the fingertip on a human’s middle finger or toe.
What bones make up the coffin joint?
The coffin joint is also called the distal interphalangeal joint (Figure 1). This articulation is a ginglymus joint formed by the second and third phalanges and the distal sesamoid bone (navicular bone).
How long does it take for coffin joint injections to work?
The effect of the medication typically maximizes in 2 weeks post-injection, so wait 2-4 weeks to assess the initial response.
How do you know if your horse has a coffin bone rotation?
Horses with laminitis are also typically sensitive to hoof tester pressure over the toe. 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.
What causes coffin joint pain in horses?
The most common causes of lameness in the coffin joint are synovitis (inflammation of the joint capsule) and osteoarthritis. Other abnormalities include: trauma, ligament inflammation (desmitis), and fractures to the phalanx bones.
What is the fastest way to reduce inflammation in the joints?
If you think your joint inflammation is due to a sudden injury, the RICE (rest, ice, compression, and elevation) method is the first line of treatment to reduce pain and swelling. See an orthopedist if the pain and swelling don’t diminish after RICE treatment.
Why would a horse need coffin joint injections?

What are three types of joints in a horse?
What are Joints?
- Synovial Joints: Synovial joints are the most common in the horse’s body.
- Fibrous Joints: Fibrous joints are less common; these joints do not allow for movement.
- Cartilaginous Joints: This category includes joints connected by cartilage, such as those between the vertebrae of your horse’s backbone.
Can a horse with navicular be ridden? Depending on the severity of the disease, it is possible to ride a horse with navicular, as long as your vet okays it. Pharmaceutical agents which can help alleviate pain and control inflammation such as Previcox and Tildren can be administered.
Can a horse recover from a rotated pedal 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 attaches the coffin bone to the hoof wall?
laminae
Inner Wall or Laminar Layer
The inner wall supports a multitude of leaf-like laminae, which attach the coffin bone to the inside of the hoof wall. These laminae bear much of the weight of the horse.

How long does it take for a coffin bone fracture 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.
