Lower limb spasticity in cerebral palsy is responsible for a variety of foot deformities1.
These include1:
equinus (plantar flexion)
hallux valgus (fixed abduction of the first metatarsophalangeal joint of the great toe)
equinocavovarus (plantar flexion, high-arched foot, adduction and inversion)
equinoplanovalgus (plantar flexion, flat foot, abduction and eversion)
Subtalar arthroereisis is a non-fusion surgical technique for the management of "collapsing" or flexible pes planus (flat feet) in a cerebral palsy child2.
