Contractures in cerebral palsy.

Contractures in cerebral palsy (CP) are usually in flexion at the hips and knees, and in plantar flexion at the ankles. When correctly indicated, surgical release is appropriate. Occasionally, extension contractures of the hip and knee develop, and dorsiflexion contractures of the ankle may ensue. In CP, the management of each of these deformities may require different sets of operative procedures.
