Barbaro Has Cast Replaced On Shattered Right Hind Leg.

Updated: June 13, 2006, 2:35 PM ET Associated Press Horse Racing News Wire KENNETT SQUARE, Pa. -- Barbaro had the cast replaced on his shattered right hind leg Tuesday, another huge stride in the recovery of the Kentucky Derby winner who suffered a life-threatening injury at the Preakness. Barbaro's cast was replaced under general anesthesia, and the 3-year-old bay colt had a very smooth pool recovery, the University of Pennsylvania School of Veterinary Medicine's New Bolton Center said in a statement. Dean Richardson, the chief of surgery at the George D. Widener Hospital for Large Animals, replaced the cast he first put on Barbaro's leg during surgery May 21. "His leg looks excellent," Richardson said in the statement. "The incision has healed well and judging by the radiographs, the graft is opacifying (taking). Callus is forming nicely, and all of the implants look unchanged." Barbaro remains in intensive care at the New Bolton Center, where he underwent five hours of surgery one day after he broke a few hundred yards from the starting gate at Pimlico Race Course.
