Barbaro remains in stable condition with good vital signs after a restful night, according to a release from the New Bolton Center, where the colt owned by Roy and Gretchen Jackson continues battling laminitis."Yesterday afternoon we changed his right hind leg cast to take new radiographs and to examine the incision," said chief of surgery Dean Richardson in a release from the equine hospital. "The radiographs looked good; the plates we placed on July 8 to fuse the pastern are intact and the fetlock fusion is unchanged. The leg and the incision looked as good as we could have hoped." The right hind leg cast supports the repair of the injury suffered at the May 20 Preakness (gr. I), and it extends from the colt's foot to just below his hock. The modified foot cast, which acts like a bandage on Barbaro's left hind foot, was also changed yesterday. The foot cast is rigid and provides stability and support, but will be changed often so that the hoof can be treated. Both cast changes were performed with Barbaro lightly sedated in a sling. He has adapted very well to being managed as needed in the sling. "He is a very intelligent horse," said Dr. Richardson. Barbaro, winner of the Kentucky Derby Presented by Yum! Brands (gr. I) continues to be monitored closely in the intensive care unit of the George D. Widener Hospital at the University of Pennsylvania's New Bolton Center.
