Radiographs were made of the feet of seventy-four normal infants and
children who ranged in age from six to 127 months, and various angles were
measured. Means and deviations of the measurements were calculated for
eleven clinically useful angles. On the anteroposterior radiographs the
talocalcaneal, talus-first metatarsal, and calcaneus-fifth metatarsal
angles were recorded, and on the lateral radiograph the talocalcaneal,
tibiocalcaneal, tibiotalar, talus-first metatarsal, and talohorizontal
angles were documented. On lateral radiographs that were made with the foot
in maximum dorsiflexion, the talocalcaneal and tibiocalcaneal angles were
documented and the talocalcaneal index was recorded. The mean values and
the ranges of normal values changed with age. These data provide a standard
for assessment of initial and residual deformity in patients who have club
foot, vertical talus, metatarsus adductus, or other deformities.
