Standing anteroposterior radiograph of both feet, in a ten-year-old girl, before surgery. The landmarks for measuring the talo-navicular-coverage angle are indicated. On the left side, the value is positive indicating mild abduction of the forefoot. On the right/ spastic equinovarus side, the angle is negative, indicating marked abduction of the forefoot. The marked difference in anteroposterior talo 1st metatarsal angle is also obvious but not marked with arrows, in the interest of clarity.
