The yellow lines mark the distance between the top and bottom part of the coffin bone relative to the hoof wall, showing the distal (bottom) of the coffin bone is rotated away from the hoof wall. Laminitis is an inflammation of laminae that affects the feet of ungulates and is found mostly in horses and cattle. Clinical signs include foot ...
The hoof is made up of two parts. The outer part, called the hoof capsule, is composed of various cornified specialized structures. The inner, living part of the hoof, is made up of soft tissues and bone. The cornified materials of the hoof capsule differ in structure and properties.
Orthopedic causes of lameness are very common and may be the result of damage to the hoof, bone, joints, or soft tissue. Horses are predisposed to orthopedic lameness by conformational flaws, poor hoof balance, working on poor footing, repetitive movements, poor conditioning for a given activity, and competing at a very high athletic level.

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 ...
Some horses benefit from shoes that change the breakover of their foot (like a rolled toe). With or without shoes, the hoof must be trimmed in such a way as to restore the balance and angle that may have been lost. Horses with long toe-low heel conformation need careful trimming to counter this.
Proper hoof trimming and shoeing is essential following surgery. The horse is at-risk of subluxation of the coffin joint, which may be counteracted by raising the heels of the horse. [125] The toe may also lift off the ground when the horse weights its heels, which may be counteracted by adding heel extensions to the shoe.
The horse laid on its side recovering from the ordeal, but it popped onto its feet shortly after. The video shows rescuers using a lead rope attached to a bridle to inch the horse away from the water.
As horses become older, the cannon bone becomes stiffer and thus bucked shins rarely occur again. Approximately 12% of horses that develop bucked shins go on to have stress or saucer fractures later. [46] Bucked shins force 7% of racehorses to retire. [47] Splints are new bone formation (exostoses) along the involved splint bone. [48]
