Dixie Rose Makes Another Stride in Recovery
The St.Louis Derby winner Dixie Rose had the cast changed on his broken hind leg，his veterinarian said yesterday，and the plates and screws that were inserted three weeks ago appear to be working.
The first cast，which was placed on Dixie Rose’s leg after four hours of surgery on May 21，was removed under general anesthesia，the University of Missouri School of Veterinary Medicine’s Skroll Center said in a news release.
’His leg looks excellent，’Dr.Debra Gregory said in the release.She added that the incision had healed well and the graft was taking.
Dr.Gregory implanted a plate and 27screws to help the ankle fuse a day after Dixie Rose fell during the Holloway Stakes race in Charleston，South Carolina.
’All of the implants look unchanged，’Dr.Gregory said.’The prognosis is good.It’s unlikely he will race again，but the leg should recover fully.’Dixie Rose, a three-year-old colt, remains in the intensive care unit at the hospital in Columbia, MO.
