- Metaphyseal osteophaty is a condition of young dogs which is most often seen following an inflammatory condition, such as viral diarrhea. The condition is characterized by suppurative inflammation in the metaphysis adjacent to the growth plate, with lysis of primary spongiosa, essentially a fracture without displacement (infraction.) Attempts to stabilize this area by the production of periosteal new bone results in a "mushroom" type flare over the painful distal metaphyses of the legs. While most commonly seen in the legs, lesions may also be seen in other bones, including the vertebrae. It has also been seen in litters of puppies with leukocyte adhesion.
