		Strictly speaking, "navicular disease" is pain or lameness that results from a problem with the navicular bone, but the term is loosely used to mean any pain or lameness that comes from the heel, including that arising from soft tissue structures.
		When the navicular bone is involved, the onset is gradual and the disease is progressive.
		Quarter horses are anatomically predisposed to navicular disease.

	How To Conquer The Accessory Navicular Bone
		It is important to examine the posterior tibial tendon and measure the extent of pain to this tendon proximal to the navicular bone.
		Perhaps the most common of the extra bones in the foot, the accessory navicular bone is estimated to be present in 7 to 19 percent of the population.
		Zadek and Gold maintained that the bone persisted as a distinct, separate bone in 2 percent of the population.

		The navicular bursa is a synovial "sac" between the navicular bone and DDF tendon and serves to lubricate the tendon as it slides over the back of the navicular bone.
		In summary, navicular inflammation appears to be a disorder triggered by an excessive bone remodeling response.
		Bone remodeling occurs as a result of excessive pressure across the navicular bone by the DDF tendon.

		More than 15 years of research and experience with the treatment of navicular disease have revealed that pressure on the navicular region, as a result of excessively long bars and heels, leads to a painful inflammation of the corium adjacent to the navicular bone and, therefore, clinical lameness.
		The enlarged cavities in the navicular bone, demonstrable by X-ray diagnosis, are not painful and therefore are not related to clinical lameness.
