Hypothesis 1

TraumaÑsoft tissue

Since soft tissue swelling is present along with pitting edema, suggests trauma to soft 
tissue.  Is this primary cause of lameness?  Manipulation/exam of joint (flexion test) 
designed to exacerbate the soft tissue or subchondral bone pain often associated with 
joint disease.  No pain in foot (on hoof testing) and no punctures noted, so localized to 
fetlock.  Possibility of partially torn ligament.  Further diagnostics necessary.
