The lower extremity manifestations of Prader-Willi syndrome.

Abstract

A case of a rare genetic disorder with typical lower extremity and gait alterations as the chief concern was presented. A description of the characteristic lower extremity and gait manifestations of this syndrome has been developed. The major and minor diagnostic criteria, which have been published to identify this syndrome, were reviewed with respect to this case. The practitioner who has the opportunity to evaluate patients for gait and lower extremity complaints should be aware of these correlations to aid in timely diagnosis of this condition. Management of compensations from these lower extremity pathologies may improve stability and prognosis for normal function. Management may also include surgical correlation of deformities found in association with this syndrome.
