What is a Type 3 navicular?

What is a Type 3 navicular?

Type III, also known as cornuate or gorilliform navicular, is characterized by a very prominent navicular tuberosity resulting from bony fusion of the accessory ossification center with the tuberosity. Most cases are asymptomatic, but ANB may cause pain and tenderness in a small proportion (<1%).

How do you identify navicular?

The telltale signs include:

  1. Intermittent forelimb lameness. Sometimes the horse seems sound in the pasture but is clearly lame in work.
  2. Short, choppy strides.
  3. Pointing a front foot or shifting weight from one foot to the other when standing.
  4. Soreness to hoof testers over the back third of the foot.

What does navicular disease look like?

A history of intermittent low grade or recurrent lameness is suggestive of navicular disease. Affected horses often appear to place the toe down first, as if trying not to put weight on their heels (in contrast to laminitis), and the lameness is worse on the inside leg on a circle.

What does navicular mean in a horse?

Navicular disease in horses is also known as Navicular syndrome. The result is the inflammation or degeneration of the navicular bone and its surrounding tissues, typically in the front feet of the horse. This disease can lead to significant or disabling lameness of a horse.

What is Type 2 Naviculare?

Type II is a secondary ossification center of the navicular bone and is also referred to as “prehallux”, accounting for approximately 50-60% of accessory navicular bones. It is seen over the medial pole of the navicular bone at between nine and 11 years of age (3).

What is Type 2 accessory navicular bone?

The type II accessory navicular is the most commonly symptomatic variant with localized chronic or acute on chronic medial foot pain and tenderness with associated inflammation of overlying soft tissues. Plain radiographic identification of the accessory navicular is insufficient to attribute symptomatology.

Can you ride a horse with navicular syndrome?

Turn your horse out in a pasture or paddock all day every day, if possible, and limit his time in the stall. If he’s still sound enough to ride, try to do so only on soft footing. Depending on the severity of his condition, you might also want to avoid riding him on circles or longeing.

What is human navicular?

The navicular bone is one of the seven bones which make up the tarsus of the Ankle and Foot. It is located on the medial aspect of the foot, next to the cuboid bone, anterior to the head of the talus and posterior to the cuneiform bones. It is one of the five bones of the midfoot.

What are signs of navicular in horses?

Clinical signs of navicular disease include a short, choppy stride with lameness that worsens when the horse is worked in a circle, as when longeing. Frequent stumbling may occur at all gaits, even the walk, or when horses are asked to step over short obstacles such as ground poles.

Why is there a bone sticking out of the inside of my foot?

The accessory navicular (os navicularum or os tibiale externum) is an extra bone or piece of cartilage located on the inner side of the foot just above the arch. It is incorporated within the posterior tibial tendon, which attaches in this area and can lead to Accessory Navicular Syndrome.

Why does my navicular bone stick out?

This can result from any of the following: Trauma, as in a foot or ankle sprain. Chronic irritation from shoes or other footwear rubbing against the extra bone. Excessive activity or overuse.
