For example, clubfoot has been associated with other structural abnormalities 10% to 14% of the time in neonatal series and as high as 80% in prenatal series (5 ,7,8). It can also be associated with many genetic syndromes (3 ,4). Clubfoot is a combination of 4 deformities: 1  Hindfoot equinus (reversed calcaneal pitch).2  Hindfoot varus (inward rotation; talocalcaneal angle of almost zero on AP view with bones parallel to each other).t can also be associated with many genetic syndromes (3 ,4).
