A total of 3,278 consecutive newborns were examined clinically for instability of the hip. Thirty children (9.2/1,000) with 42 unstable hips were detected. All were treated with an aluminum malleable brace. The brace was worn continuously for six weeks.At that time the hip was then examined clinically; if stable all restrictions were discontinued. At three months and one year the child was reexamined and re-x-rayed. All were normal clinically and roentgenographically except for one child with a diagnosis of gargoylism.The complete diagnosis of congen¬ ital instability of the hip may be made in the newborn nursery. The treatment is relatively easy, short, and the results are excellent.113
