Its completely severed itself (the tendon) Im not a vet and too familiar with tendons and where they run. Google is telling me that the lateral and long run into each other down the front of the cannon and it split right about mid cannon centered. When I checked on her yesterday she was in a better spirits and mobile again. So odd, not even rolling on her toe.... The vet must have put her back on the pain meds. I was hoping to run into my vet yesterday and having a laundry list of questions and suggestions I hate to bother him on a Sunday. The wound itself looked well It finally hardened over but with a very 'pace'y' horse, she wouldnt allow me to get a good look at it. She gets a little passive aggressive having to be stall confined. I will continue to post progress pictures and hope it could be a reference to someone else's same situation.
