Ultrasonography in the diagnosis of congenital hip dysplasia in the newborn

Summary

A new technique for ultrasonic examination of the hip is aimed at identification of the acetabular cartilaginous ridge, called the “neolimbus” by Ortolani. The presence of this ridge is pathognomonic for congenital hip dysplasia in the newborn. Ultrasonography of 300 normal hips never showed the neolimbus, but it was present in 25 dysplastic hips. Ultrasound examination of the hips of newborn infants can therefore be combined with the Ortolani test in the very early diagnosis of hip dysplasia.

Résumé

Description d'une nouvelle technique échographique d'exploration de la hanche, méthode élective de détection de la crête cartilagineuse acétabulaire qu'Ortolani appelle “néolimbus”, pathognomonique de la dysplasie congénitale du nouveau-né. Cette technique a été utilisée pour analyser trois cents hanches normales et vingt-cinq hanches dysplasiques de nouveau-nés soumis à notre évaluation. Dans les cas de dysplasie, le diagnostic clinique avait toujours été préalablement porté grâce à l'observation du signe d'Ortolani. Dans les trois cents hanches normales, l'échographie n'a pas montré la présence de néolimbus, tandis que celui-ci a toujours été observé dans les vingt-cinq hanches dysplasiques. Puisque c'est la présence de ce néolimbus qui détermine la positivité du ressaut d'Ortolani et que cette présence peut être décelée grâce à notre technique échographique, je propose l'utilisation de cette méthode, associée à l'évaluation clinique, pour un diagnostic précoce et correct de la dysplasie congénitale de la hanche.
