Lateral Release to the Foot Deformity of the Planovalgus in Children of Cerebral Palsy

Abstract

Rehabilitation of the patient with cerebral palsy depends on the restoration of muscle balance. And no therapeutic program for cerebral palsy can succeed without restoration of muscle power. Planovalgus deformity of the foot would be not merely the deformity of the foot but also the cause of the scissors position.In our series, lengthenings of Achilles tendon show definite tendency to causes eversion of foot. This finding would mean that triceps surae has function of plantar flexor with inversion of the foot and if be weakened, the power of inversion is also weakened. Muscle balance is then destructed and eversion foot appears.In order to restore this muscle balance, such as weakness of inversion power, we lengthen evertors of the foot, such as peroneus brevis. And we can attain plantigrade foot and establishment of correct posture.
