Routine ultrasound screening for neonatal hip instability. Can it abolish late-presenting congenital dislocation of the hip?

Author information

Coventry & Warwickshire Hospital, England, UK.


We have undertaken routine ultrasound screening for neonatal hip instability in Coventry since June 1989. Of the 14,050 babies scanned during the first three years, 847 (6%) had ultrasound abnormalities. A grading system, based on the percentage of femoral head coverage, is presented. The proportion of abnormal hips decreased gradually so that by nine weeks, 90% had normal ultrasound appearances. Abnormality was more common in babies with a family history of CDH and in breech presentations. All babies with clinically abnormal hips had an abnormal first ultrasound examination. Five babies not diagnosed by clinical examination and with no risk factors had abnormal ultrasound appearances and were subsequently found to have clinically abnormal hips. Routine ultrasound screening has detected cases which would otherwise have presented late.
