Radiograph of a horse hoof showing rotation of the coffin bone and evidence of sinking, a condition often associated with laminitis. The annotation P2 stands for the middle phalanx, or pastern bone, and P3 denotes the distal phalanx, or coffin bone. The yellow lines mark the distance between the top and bottom part of the coffin bone relative ...
Hoof or horseshoe wear can indicate breakover and if the horse is dragging its toes. Change in shape of the hoof wall is also common in horses with laminitis. "Founder rings," or thickened concentric rings in the hoof wall, indicate a past episode of laminitis. Concavity of the dorsal (front) surface of the hoof can indicate chronic laminitis.
The contralateral (opposite) leg then bears all of the weight, which reduces blood flow to the hoof and strains the attachments of the laminae, leading to laminitis. Although support-limb laminitis is a risk for any horse that is not weight-bearing lame, occurring in roughly 16% of cases, it is uncommon in foals and yearlings. [ 135 ]
By July 13, Barbaro had developed a severe case of laminitis in the left hind hoof—a potentially life-threatening affliction that is common in horses who shift weight to one hoof for extended periods to keep pressure off an injured hoof. A procedure called a hoof wall resection removed 80% of his left rear hoof. The remaining 20% of his hoof ...
Early intervention is key; in one study, shoeing was successful in 97% of horses treated within ten months of the onset of signs, while only 54% of horses lame for over a year responded. [ 16 ] Advocates of barefoot trimming cite recent studies which show that removing the shoes can help alleviate the symptoms of navicular disease, and in some ...
Horses are best managed by only allowing short grazing periods—less than 1 hour since they can rapidly ingest grass, [18] or confining them to a limited turn-out area or by use of a grazing muzzle. Horses with severe IR, that have recurrent laminitis, are not recommended to return to pasture. Hay low in NSC is provided in place of pasture.
A long neck is one that is more than one third the length of the horse. Long necks are common, especially in Thoroughbreds , Saddlebreds , and Gaited Horses. A long neck may hinder the balancing ability of the horse, and the horse may fatigue more quickly as a result of the greater weight on its front end.
The main tendon in the hoof is the deep digital flexor tendon, which connects to the bottom of the coffin bone. The impact zone on the bottom of the hoof includes the sole, which has an outer, insensitive layer and a sensitive inner layer, and the frog, which lies between the heels and assists in shock absorption and blood flow.
