Cavus foot in cerebral palsy.

In the child between 4 and 12 years of age presenting with cavus deformity associated with spastic cerebral palsy, symptomatic feet may be improved by soft tissue release of plantar structures followed by appropriate tendon lengthenings or transfers and good cast correction. It is more common for the deformity to present in teenage patients, however, with a more rigid foot usually complicated by some degree of varus and equinus. In these situations, triple arthrodesis is often necessary and is a predictable procedure for correction and stabilization of the deformity.
