What bones are in a horse’s body?

They are also able to flex the neck and “arch” it. Chest- The chest is the front of the horse and houses the powerful pectoral muscles. Shoulder- Where the shoulder blade is found, and is connected to one of the front leg bones. Horses don’t have a collar bone like humans do.

How does a horse’s skeleton work?

Like a machine runs, the bones of a horse’s body all work together to support and make the basic frame of the horse. The front legs of the horse are actually one of the most important parts of the horse’s skeleton as these legs alone carry 60% of the horse’s entire weight. Above is an image of the entire skeleton of a horse.

What is the navicular bone for in a horse?

The navicular bone functions as a pully for the deep flexor tendon that wraps around the navicular and is attached to the pedal bone. The horse leg anatomy in the rear includes the bones of the pelvis (the ilium, ischium and pubic bones), femur, tibia, fibula, metatarsus and the phalanxes.

What is the function of the skeleton of a horse?

The Horse Skeleton & how your horse is put together. The horses skeleton gives support for the muscles; protection for the internal organs; and possesses enough mobility in its parts for the horse to move at differing speeds or to lie down or to graze.

What is the longest bone in a horse’s body?

The femur is the longest bone Just as with humans, the longest bone in a horse’s skeleton is the femur. The precise length, of course, varies according to the breed, sex and maturity of the animal. When it comes to flat bones, the pelvis is the largest.

Why does my horse ride with his hind end bent?

He also has to initiate movement from the front end, which will result in the front end pulling the hind end along. When there is little reach of the hind legs underneath the horse’s body, there is little he can do to maintain his own balance, never mind the balance of his rider’s weight too.

Is there a prognosis for navicular bone problems in horses?

Though the prognosis is poor in the case of navicular bone problems, careful management can reduce the sufferings of your horse. As a horse owner, you must take care of the causes of navicular syndrome.

What are the different views of the navicular bone?

These include the angular dorsoproximal-palmarodistal views, the lateromedial view, and the palmaroproximal-palmarodistal (also called skyline) view (Box 24-1). 2 The horizontal beam dorsopalmar view is an additional view that is helpful for evaluating the extremities of the navicular bone.

What happens if a horse fractures the navicular bone?

Because of its location within the hoof structure, fractures of the navicular bone are rare. When they do occur, these fractures usually lead to sudden lameness. Navicular fractures occur most often when a horse kicks a stationary object, such as a post or wall.

What is the shape of the navicular bone?

In the angular dorsoproximal-palmarodistal views, the navicular bone is of uniform radiopacity. Its spindle shape varies somewhat from horse to horse. The extremities are fairly symmetric and are bluntly pointed. The proximal border is smoothly marginated.

What is the longest bone in a horse’s skeleton?

Just as with humans, the longest bone in a horse’s skeleton is the femur. The precise length, of course, varies according to the breed, sex and maturity of the animal. When it comes to flat bones, the pelvis is the largest. And at the other end of the scale, the smallest bones in the equine skeleton are in the ears.

Is navicular disease a death sentence for a horse?

While navicular disease is a degenerative condition, this diagnosis is certainly not a death sentence for your horse when it is identified in its early stages. Certain breeds, such as Quarter horses and Paints, are more likely to develop the condition than others.

What is a “navicular” bone?

What is a “navicular”? The navicular is a small bone in your horse’s foot at the back of the coffin joint. It is technically a sesamoid bone, meaning it is not one of the main weight-bearing bones in a joint. Despite this, navicular bones play a huge role in the physiology of how a horse’s foot bears weight.

What is the prognosis of navicular disease in horses?

Case series of navicular disease have shown a favourable prognosis, at least in the short term, with medication of the navicular bursa (the area around the bone itself) using corticosteroids and/or hyaluronic acid. As navicular worsens with hard exercise, you may also need to look at reducing your horse’s workload.

Is the navicular bone in a horse the same as human?

The central tarsal bone in the hock of the horse is homologous and analogous to the navicular bone of the human foot, and thus the navicular bone in the horse is a different structure from the eponymously labeled bone in humans.

What is the navicular view used to evaluate?

This view is useful in evaluating the extremities of the navicular bone, particularly when subtle abnormalities are suspected. In the angular dorsoproximal-palmarodistal views, the navicular bone is of uniform radiopacity. Its spindle shape varies somewhat from horse to horse.

What does navicular disease look like in a horse?

A horse would present with a front limb lameness. The lameness would be localized to the foot. Radiographs taken of the foot showed degenerative changes in the navicular bone, and the horse was diagnosed with navicular disease. Today we know that navicular syndrome is much more complex.

What is the best treatment for navicular disease in horses?

Long term treatment with substances such as isoxsuprine and aspirin may improve blood supply to the navicular bone and improve the condition of the bone. Warfarin used to be a popular treatment. It ‘thins’ the blood and seems to help some horses although its use can predispose to excessive bleeding after coincidental injury.

What should I do if my horse has a navicular fracture?

The severity of the navicular bone fracture will play a role in your horse’s recovery. You need to give your horse plenty of time to rest and heal. Prognosis is guarded for soundness; if you want your horse to maintain his athletic career, he may need a palmar digital neurectomy.

What is the normal anatomy of the navicular bone?

Anatomy The normal radiographic anatomy of the navicular bone (distal sesamoid bone) is shown in Chapter 13. The navicular bone has two surfaces (flexor and articular), two borders (proximal and distal), and two extremities (medial and lateral).

What causes foot fractures in horses?

Fractures may also be caused by an accident involving the foot that puts unusual pressure on the hoof and foot structure, including the coffin bone, the tendons, and ligaments.
