Usually divides the deformation of the foot in four places:
Horses, in which the heel is elevated plantar flexion of the foot.
Calcaneus, in which the foot is in dorsiflexion and heel has declined relatively.
Varo, which is invested and adduction.
Valgus, which is its outward deviation, ie eversion and abduction. Deformities sometimes consist only of the positions identified but in most cases are combinations of the foot or the heel quino with varus or valgus.
