Untreated congenital hip dysplasia in the Navajo.
Congenital hip dysplasia without dislocation was identified in 18 Navajo Indian children. Treatment had been declined and the children presented a unique opportunity to observe the natural course of hip dysplasia. In a follow-up period of three to 19 years (average, 11.2 years), none of the dysplastic hips were observed to progress to dislocation. In 15 of the children with dysplastic hips, the condition became roentgenographically normal in the course of normal growth and development. The other three children continued to show roentgenographic signs of hip dysplasia.
