Early Abduction Splintage on Stable Hips in Infants With Developmental Dysplasia of the Hip

NCT02885831 | Completed

• 1 other identifier: 29BRC17.0021
• Study Type: observational
• Target: 90
• Locations: 1 country
• Sites: 1

Brief Summary

The aim of this study is to prove the improvement of pubo-femoral distance by early abduction splintage in one-month-old infants with developmental dysplasia of the hip (with a clinical stable hip but an abnormal hip ultrasonography).

Conditions

Congenital Hip Dysplasia

Keywords

Abduction splint; Pubo-femoral distance

Outcome Measures

Primary Outcomes (1)

• Normal or abnormal hip ultrasound

  A normal or abnormal hip ultrasound will be base on two outcomes : * Pubo-femoral distance (ultrasonographic measurement) : distance between the pubic bone and the cartilaginous femoral head, considered as normal if lower than 6mm. * Bony rim percentage (ultrasonographic measurement) : percentage of the cartilaginous femoral head covered by the acetabular roof, considered as normal if higher than 50% (or equal to 50%). * Data of pubo-femoral distance and bony rim percentage will be pooled to determine if the ultrasound is normal or not for each patient. If one out of two is abnormal, ultrasound is considered abnormal. Statistics will be based on this qualitative value : normal or abnormal ultrasound.
