Calcaneal valgus is a disorder that arises in newborns due to their position within the womb. It usually only affects one side. The forefoot is abducted and dorsiflexed while the heel is valgus. The ankle’s range of motion is restricted. As a result of the foot posture, an external tibial torsion may arise and an externally rotating tibia in rare circumstances. With greater tension in the ipsilateral peroneus longus muscles and iliotibial band and reduced ipsilateral sacroiliac mechanics, the fibular head may be posterior. Muscular deconditioning and aberrant firing patterns are common, as they are with other congenital abnormalities. Rehab is required for the plantar flexor and inversion muscles.
