During the past two decades, there has been great progress in the man agement of clubfoot. The First International Congress on Clubfeet was a landmark gathering of the leaders in the world in the treatment of club foot. The congress was organized by Dr. George W. Simons-a difficult and demanding task. The quality of the papers published in this mono graph reflects his pursuit of excellence and attention to detail. Still, there are many controversies in the management of clubfoot; it is evident that there is disagreement as to terminology and definition. What is congenital talipes equinovarus? It is a deformity of multifacto rial pathogenesis in which the heel is inverted, the forefoot and midfoot are inverted and adducted (varus), and the ankle and subtalar joints are in equinus position. The forefoot is in cavus with the toes at a lower level than the heel. It is vital, however, that one be more specific in the defini tion of talipes equinovarus.
