Functional classification and orthopaedic management of spinal muscular atrophy

Abstract

The majority of patients with chronic infantile and juvenile forms of spinal muscular atrophy survive to adult life. Forty-four patients have been reviewed at an average of 17 years after diagnosis. The subdivision of patients into four groups, based on the maximal physical function developed by the individual, correlates well with the onset and severity of secondary deformity of the limbs and spine. This information allows anticipation of the problems and plans for their treatment to be made from early childhood. After analysis of the orthotic and surgical treatment received by these patients, a specific programme of care is recommended for each of the functional groups.
