(a) Front view and (b) posterior view in the same standing position. When the patient is asked to turn the trunk and pelvis to the right, the right lower limb is subsequently externally rotated while the left lower limb is internally rotated, leading to a pes cavo-varus of the right foot and a pes plano-valgus of the left foot (from Seringe and Wicart 2013).⁹ This figure has been reproduced with permission.
