The aim of this study was to evaluate whether universal (all neonates) or selective (neonates belonging to the risk groups) ultrasound screening of the hips should be recommended at birth.

We carried out a prospective, randomised trial between 1988 and 1992, including all newborn infants at our hospital. A total of 15 529 infants was randomised to either clinical screening and ultrasound examination of all hips or clinical screening of all hips and ultrasound examination only of those at risk. The effect of the screening was assessed by the rate of late detection of congenital or developmental hip dysplasia in the two groups.

During follow-up of between six and 11 years, only one late-detected hip dysplasia was seen in the universal group, compared with five in the subjective group, representing a rate of 0.13 and 0.65 per 1000, respectively. The difference in late detection between the two groups was not statistically significant (p = 0.22).

When clinical screening is of high quality, as in our study, the effect of an additional ultrasound examination, measured as late-presenting hip dysplasia, is marginal. Under such circumstances, we consider that universal ultrasound screening is not necessary, but recommend selective ultrasound screening for neonates with abnormal or suspicious clinical findings and those with risk factors for hip dysplasia.

In 100 consecutive patients with chronic deficiency of the anterior cruciate ligament we reconstructed the ligament using a bone-patellar tendon-bone autograft either with or without a Kennedy ligament augmentation device. The patients had an aggressive rehabilitation programme supervised by two physiotherapists.

They were followed prospectively for at least two years by one surgeon, and assessed after six months and at one and two years. No significant functional or clinical difference was found between the two groups and the stability of the knees did not deteriorate with time in either group. The addition of a Kennedy ligament augmentation device gave no better results than the bone-patellar tendon-bone technique alone.

The hips of 1000 newborn babies were examined clinically and by ultrasonography. The ultrasound assessment was based on measurements of the coverage of the femoral head by the bony acetabular roof, and this parameter was called the Bony Rim Percentage (BRP). The mean BRP was 55.3% in girls and 57.2% in boys, a significant difference. Clinical instability occurred in 0.7% of the newborn babies, and all of the unstable hips had a BRP below the lower limit of normal. All infants with normal clinical findings and suspected abnormal hips based on ultrasound were followed up; in all but two the hips became normal spontaneously. We conclude that ultrasonography, using the measurements of femoral head coverage, is appropriate for screening the newborn, is reliable in differentiating between a true and a false positive Ortolani sign, and that hip dysplasia which is not clinically demonstrable at birth can be detected by ultrasound. Ultrasound should replace radiography as the routine method of following up high-risk infants and those with suspicious signs.
