title: Familial occurrence of protrusio acetabuli (Otto's disease). Ten members affected in four generations.
abstract: It is rare for hereditary forms of primary protrusio acetabuli to be reported, and the mode of transmission is not always clear. The writers present a familial occurrence of this malformation in which the hereditary factor was in accord with the presence of a dominant autosomal gene.
