Early detection and low-risk treatment are the two main objectives of the m
anagement of developmental dislocation of the hip. The best way to evaluate
neonatal hips is to perform clinical and ultrasound examinations at the sa
me time, and to confront their results. Early diagnosis allows to restrict
treatment to infants with neonatal dislocation who do not improve by 4 week
s of age. On the other hand, neonates with reductible dislocated hips must
be treated at birth and followed at the joint consultation. Early diagnosis
and management must not decrease later efforts to detect dislocated hip un
til walking age. (C) 1999 Elsevier, Paris.
