	After further debate and consultation, it was determined that the right distal 
metatarsus is not necessarily fractured, but the radiolucent line could just be the distal 
growth plate of the cannon bone. Growth plates are very large and often difficult to 
distinguish from an acute traumatic fracture, but this particular case appears to be a 
normal but potentially inflamed growth plate. We have not ruled out the possibility of a 
fracture or physitis, and our treatment will be aggressive with constant monitoring of the 
joint so any changes in diagnosis and treatment can be made.

	The total protein within the joint is only 2.7 g/dL, and there is no leukocytosis or 
left shift to indicate inflammation of severe tissue demand. However, K. pneumoniae was 
cultured from the joint, and this could only invade the joint capsule through trauma to the 
capsule or surrounding fetlock joint structures. Aggressive treatment with systemic 
antibiotics like amikacin should halt any further bacterial growth and prevent the septic 
arthritis from worsening.
