I paid around £140 for 2 plates. No sedation not including call out. Mine were only for the foot. Maybe give your vet a quick call for a quote. Hope that helps.
my bill came to just under 400 including xrays on both fronts (this included his pedal, pastern and navicular) this also included sedation as he was a fidget!
We charge a visit, sedation (if the horse needs it) and £180ish for 8 plates ( up to 4 views of each leg for comparison) any extras are about £15 each one, unless its to do a better one cos we cant see it very well !!
if you are worried about tendons as well though, thats a scan - and thats about £160ish for both legs (again for comparison - most vets do this because something that is on one leg and looks like a problem might well be on the other and completely normal for that horse!)
Fingers crossed they show whatever you want them to show.
