Veterinarians in Pennsylvania have made another cast change on the injured leg of Kentucky Derby-winner Barbaro. The horse continues to make slow progress after shattering his right hind leg at the start of the Preakness race in May.
Most horses with similar injuries are usually euthanized because recovery is nearly impossible. A common complication is laminitis, which is often fatal. Barbaro developed the disease in his left hoof, which was largely removed several weeks ago. Doctors say it shows signs of regrowth and appears healthy. Barbaro's right hind bones are healing so well his cast could be off by now if not for the laminitis.
Barbaro's owners have decided to continue treatment as long as he remains comfortable and free from pain.
