[Comparative evaluation of clinical and ultrasonographic screening of hip dislocation in Breton and Languedoc populations].
BACKGROUND
Congenital dislocation of the hip varies greatly in incidence among different regions. This work is aimed at comparing results of clinical investigation and ultrasonography of the hip in Languedoc-Roussillon and Brittany.


METHODS
Two thousand eight hundred and twelve and 2,809 neonates admitted to Nîmes and Vannes hospitals respectively, were enrolled in a prospective study. Clinical examinations were made according to the protocol established by the "Groupe d' études en orthopédie pédiatrique". Ultrasound investigations were performed in every risk case.


RESULTS
No dislocation occurred in the 4946 neonates without risk factors. In the 675 neonates with risk factors, 213 ultrasonographic examinations were abnormal, more frequently in the Brittany group (P < 0.001); nine dislocations were observed. A familial history of hip dysplasia (P < 0.001) and the addition of two risk factors (P < 0.001) were more frequent in Brittany. One hundred and six cases required treatment, more frequently in Brittany (P < 0.001).


CONCLUSIONS
Some clinical risk factors and delayed ossification or hip dysplasia at ultrasound examination are significantly more frequent in Brittany. Clinical examination with selective ultrasonography is a reliable method, allowing early diagnosis and treatment of delayed dislocations.
