Prognosis:

This prognosis is based on the assumption that the producer chooses not to cull the calf.  
This fracture is classified as a viable delayed union with hypertrophy.  If the intact 
portions of the metacarpal bone have functional growth plates and conformation of the 
metacarpal bone is determined to be normal external fixation may be able to repair this 
fracture.  It should be noted that the fracture is contaminated with bacteria and this may 
significantly interfere with the ability of the metacarpal to fixate.  Only with extensive 
antibiotic therapy and prolonged stall confinement will the delayed union have a chance 
of healing.  External fixation below the elbow has been used successfully in large 
animals; however, due to the extreme forces acting on the front legs (front legs carry 66% 
of body weight) it may be difficult to adequately fixate the fracture to facilitate union.  
Since this calf only weighs approximately 220 pounds, the stress across the fracture 
should be greatly reduced in comparison to a full grown bull, so we might expect union 
to occur more readily in the calf.  

The prognosis for union is moderately guarded but it is expected to occur.  However the 
prognosis for normal metacarpal conformation and lack of lameness is highly guarded 
and not anticipated due to the location of fracture and its contamination.  If this calf is 
intended for use a breeding bull you may what to consider cutting your losses now and 
culling the animal.  Without a sound front leg this animal will not pass a breeding 
soundness examination therefore its semen will have little value.
