The Foot in Cerebral Palsy.

Children with cerebral palsy frequently develop foot deformities, most commonly equinus contractures, which can be managed with orthotics up to age 5 to 7 years. Plantar flexor lengthening, typically around this age, should be restricted to the offending muscle only, usually with a fascia release of the gastrocnemius. Equinovarus, mainly a problem in children with unilateral cerebral palsy, often responds to plantar flexor lengthening. If further tendon transfers are needed, they should be done when the child is older to avoid overcorrection. Planovalgus mostly improves spontaneously up to age 5 years. Surgical correction is best done in adolescence.
