“The shoe on his right hind foot was further modified as his strength improved,” said Dr. Dean W. Richardson, Chief of Surgery. “We are aware that there is some public concern about his abnormal motion on the right hind limb, however, this is not unexpected. His gait may be abnormal as he learns to adapt to having fusions of two major joints in his lower limb and to the special shoe. In addition, the fracture had some collapse on the medial (inside) part of the pastern region after he developed laminitis on the left hind foot. Although this is visually unattractive, the mechanics of the lower leg are not seriously affected because the pastern and fetlock joints are fused.
“The right hind has healed well enough that we are optimistic about that possibility,” said Dr. Richardson. “However, Barbaro’s left hind foot, which had laminitis, remains a more formidable long-term challenge. The foot must grow much more for him to have a truly successful outcome.”
