Luxation congénitale de hanche chez l’enfant

Abstract

At one month, the acetabular depth from a standard lateral coronal section is 4.6 ± 1.0 mm. The correlation between experienced and junior radiologists is high (kappa 0.795). A treshhold of 6 mm with a Δ (difference between right and left) less than 1.5 mm provides a sensitivity of 100% for the detection of DDH at one month. Universal US screening at one month of all high-risk infants in 2009 resulted in a reduction of delayed diagnosis of DDH (zero girls, two boys) in Ille-et-Vilaine due to continuous medical education of general radiologists.
