title: Classification systems in cerebral palsy.
abstract: Because of increasing interest in conducting large-scale, multicenter investigations into the epidemiology of cerebral palsy and its prevention and treatment, efforts have been made to establish a standard definition and classification systems for cerebral palsy. In recent years there has also been increased focus on measurement of functional status of patients and new classifications for gross and fine motor function have been developed. The purpose of this article is to update the orthopaedic community on the current classification systems for patients with cerebral palsy. This information will be of value to surgeons in determining patients' suitability for certain treatments and will also assist them in reviewing current literature in cerebral palsy.
