Figure 4
Cross section through a normal hoof (top left) and a hoof from a horse with acute laminitis (top right). The arrows indicate the dorsal hoof wall covered by dermal lamina. The pedal bone in the normal hoof is parallel to the hoof wall whereas it is rotated away from the dorsal hoof wall in the hoof obtained from the horse with laminitis. Bottom left and bottom right images show a hematoxylin and eosin stain of a histology slide from a normal horse and the horse with laminitis, respectively (magnification 1× objective). The top right hoof is the right front hoof (#12) also depicted in the radiographs obtained from the horse with acute laminitis prior to euthanasia (Figs. 9 and 10). |
