Here is a story released by the NTRA regarding the updated condition of Kentucky Derby winner Barbaro:

KENNETT SQUARE, PA-- Kentucky Derby winner Barbaro is continuing to
strengthen on his right hind leg since the cast was removed
on November 6, according to his medical team. "Barbaro will need a
special shoe on his right hind foot that will provide extra support
for at least the next several months," said Dr. Dean W. Richardson,
Chief of Surgery. Barbaro's medical team plans to change his right
hind shoe within the next day or two.
Barbaro's left hind foot, which had laminitis, continues to
improve. "The left hind foot is progressing slowly although his
comfort on that foot remains acceptable," said Dr. Richardson. "Most
importantly, Barbaro's overall condition is continuing to improve and
he weighs more now than at any time during his hospitalization."
