Where this comes from

Abstract

Out of 320 patients on the Northern Ireland Perthes' database, five were known to be twins. We observed that the low birthweight twin in each case was the affected child. It is proposed that environmental factors associated with low birthweight are involved in the aetiology of Perthes' disease.
