Experience with putting a cast on a horse?

I worked for a vet for four years and only ever saw one horse with a cast on. It was a young thoroughbred colt that was born with retracted tendons. He had surgery to correct the retracted tendon on one of his front legs and had a cast on it. He was unable to bend his knee, therefore was unable to walk on his own. There was staff with him around the clock to feed him milk out of a bucket, lift him to his feet and walk him around the barn aisle for exercise. He could walk with his other legs okay, but we had to loop a lead rope around the leg in the cast and pull it out to the side and place it in front of him with every stride. He then needed help laying back down. He needed tended to every two hours and we had to flip him over ever so often to make sure he wasn't always laying on the same side. Little Philip never "messed up" his cast. It was applied at the clinic immediately following his surgery but I imagine the vet could bring the supplies to your farm instead of having you trailer an injured horse. However, if you can afford it, you may want to trailer him in and let him stay with the vet for a while if it's an injury that severe and if he is as high maintenance with a cast on as Philip was. It was hard enough to care for him with a full staff of veterinary employees. I can't imagine trying to care for him on my own. But you have to keep in mind that every case is different. Just listen to your vet's recommendations, follow their instructions, and hope for a fast recovery!
