Assessing For Forefoot Varus
A constant structural inversion of the forefoot with respect to a bisection of the posterior of the calcaneus when the subtalar joint is in neutral position. This is an inverted position of the forefoot relative to the rearfoot at the level of the midtarsal joint. It is due to inadequate frontal plane torsion occurring during normal development of the foot. Upon weight-bearing, calcaneal eversion is required to fully compensate this deformity.
