From the radiographs and joint tap, we think the underlying problem here is septic 
arthritis.  Septic arthritis is a serious condition that requires immediate action.  It can 
happen through a variety of mechanisms, though in this foal it is most likely due to 
traumatic injury from being stepped on by the mare.  A minor cut could have 
predisposed 
the foal to bacterial contamination from the environment.  Because the other joints 
are 
not yet affected, the septic arthritis does not seem to have spread, which bodes well for 
the foalÕs prognosis.  A joint lavage will need to be performed to clear out all the debris 
and inflammation currently happening, with administration of an antibiotic into the 
joint as well.  We will need to administer systemic antibiotics for at least for two 
weeks, and then we will do another joint tap and culture at that time to check for 
bacteria 
and the presence of inflammation.  We will also administer pain medication as 
needed to 
help the foal.  The foal is going to require prolonged rest from exercise to allow 
healing 
of the damaged soft tissues and articular cartilage.  Therefore, we should keep the foal 
confined here in the hospital for a few days to monitor closely for further problems 
and 
administer medication as needed.  Passive motion is important in rehabilitating and 
maintaining the range of motion in recovering joints.  This can be performed by 
gently lifting up the leg and by slowly flexing and extending the joint.  While at home, 
monitor the foal for worsening joint problems, including fever and continuing 
lameness.
