Untreated Congenital Hip Disease:A Study Of The Epidemiology, Natural History, And Social Aspects Of The Disease In A Navajo Population

Description: 

The prevalence, natural history, and environmental factors associated with congenital hip disease were investigated among a population of Navajo Indians with a high incidence of the disease. Treatment for the condition had been unavailable to the adults and was rejected by Navajo parents for their children. The research conditions permitted not only comparison of the adult and the child populations but study of the untreated course of the disease in the children. Findings suggest multigenetic factors in the etiology of the disease, with expressivity greatly influenced by undetermined environmental factors. Genetic findings, however, are highly tentative because dysplasias in the older population may have been lost due to spontaneous improvement. Tables. Genealogy trees. Photos. Bibliography.
