Swollen right hind fetlock indicates location
very lame on the right hind and refuses to use - location
thinks the mare stepped on the foal's leg- possible trauma
2 weeks old- neonate period immune system less active 
She is nursing normally- may rule out systemic illness
part of the small herd- exposed to other horses but small in 
number
Temp 101.8 - WNL rules out systemic infection
bright and alert- rules out severe systemic problem
all systems except the musculoskeletal appear within normal 
limits - rules out severe illness except for MS system
Respiratory Rate = 52- WNL? If high could be caused by 
pain
Toe touching lame worsened with palpation and 
manipulation- motion causes pain and worsen reaction
reveals soft tissue swelling (pitting edema) starting 12 cm 
proximal to the fetlock and extending just distal to it- 
localizes to fetlock- inflammation is occurring at location
No foreign body in foot nor does foal resent the hoof testers- 
rule out abscess puncture wound in hoof causing lameness
No instability or crepitance upon palpation- may rule out an 
anaerobic infection but not trauma to joint because there are 
many compensatory mech to stabilize the joint
