Laminitis
Laminitis is a disease that affects the feet of ungulates and is found mostly in horses and cattle. Clinical signs include foot tenderness which makes it harder for them to walk. It also increased digital pulses, and increased temperature in the hooves. The progression of the disease will lead to perforation of the coffin bone through the sole of the hoof or being unable to stand up requiring euthanasia.[1]
Laminitis Media
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 front feet of this horse exhibit the rings and overgrowth typical of foundered horses.
Cross-section of horse with severe laminitis, showing a dished dorsal hoof wall that grows in a more horizontal manner, and a sole that is convex due to pressure from the tip of P3 secondary to rotation.
Radiographic measurements, including coronary extensor distance (CE), horn:lamellar distance (HL), sole depth (SD), digital breakover (DB), and palmar angle (PA)
