Most but not all calcaneus feet in cerebral palsied patients are iatrogenic. The cause is related to imbalance between plantarflexors and dorsiflexors in most instances. Injudicious heel cord lengthening, inadequate preoperative assessment of anterior tibial power, heel cord lengthening accompanied by gastrocsoleus neurectomy or transposition of peroneal and posterior tibial tendons, anterior to the malleoli, are all potential causes of calcaneus deformity in cerebral palsy.
