He told the court Mr Ladhams failed to reveal during negotiations for the sale that Sound Action had undergone extensive treatment for what is known as a "navicular" problem in her front hooves.
If the foot be forcibly extended, the head of the talus appears as a rounded prominence on the medial side of the dorsum; just in front of this prominence and behind the tuberosity of the navicular is the talonavicular joint.
1819 Moorcroft made it even plainer still that he was fully acquainted with what we now know as navicular disease.
It may accompany chronic diseases of the foot, such as navicular disease and side-bones.
_ -- Horses knuckling at the fetlock, and all those with diseases which impair the powers of locomotion, such as navicular disease, contracted heels, sidebones, chronic laminitis, etc., are predisposed to sprains of the fetlock.
'navicular' have in reality been nothing more than contraction brought about by one or other of the causes we shall afterwards enumerate -- cases where a due attention to the prime cause of the mischief would, in all likelihood, have remedied the lameness.
For the price of admission, you not only get to see the competitions, but there are lectures on navicular, the pre-purchase exam, growing and baling your own hay, and equine ulcers.
On the cart lay the following: proximal and distal portions of a left femur; a fragment of proximal left fibula; two fragments of left tibia, one proximal, the other distal, including the mangled malleolus; a portion of left pelvis extending from the pubic bone out into the blade; the talus, navicular, and third and second cuneiforms from a left foot.
The “hobbit” navicular bone is more akin to that found in great apes, which means that these hominins lacked an arch and were not efficient long-term runners.
But the pivotal clue comes from the navicular bone, an important tarsal bone that helps form the arch in a modern human foot.
