Rationale for facts
2 week old fillyÑvery young, young enough to see congenital problems or navel illÑis 
navel ill ever only in one joint?Ñlearning issue.
Swollen lame right hind fetlockÑlocalized lamenessÑpossible trauma
Foal hasnÕt been vaccinated or dewormed but mare is currentÑprobably not an important 
factÑfoal is too young to be vacc or dewormed; since foal otherwise looks normal and is 
nursing we are not too worried about  FPT.  However could have fought off most of 
infection and just couldnÕt deal with infection in one jointÑseptic joint.
ThoroughbredÑany special congenital problems with thoroughbredsÑlearning issue?
Owner thinks mare stepped on foalÑpossible trauma, fracture, rupture ligaments
Toe touching lamenessÑseverity indicates not weight-bearing
Soft tissue swelling, pitting edemaÑinflammatory response to tissue trauma or infection?
No temperatureÑsuggests trauma or noon infectious although we think a foal can have 
navel ill and not show signs if it is able to localize and control infection in one jointÑwe 
are looking into this as a learning issue.
Foal resents palpationÑpain localized again to joint
No foreign body in foot and no sensitivity to hoof testerÑnot a problem with the 
hoofÑsupports even more that the problem is in the fetlock.
No instability or crepitanceÑwhat is crepitanceÑwe think this means no SQ air trapped 
i.e from bacteriaÑwe are looking into this a learning issue.
