[Why and how to examine the newborns' hips?].

The authors insist on the importance of a careful clinical examination of newborn's hips, and on the necessity of an early diagnosis of congenital hip dislocation, in order to optimize the probability of therapeutic success. They don't consider hip dislocations resulting from neuromuscular diseases or from complex malformations (e.g. arthrogryposis) included in a wider context with very different prognosis and treatment.
