Risk Factor Assessment and a Ten-Year Experience of DDH Screening in a Well-Child Population

الملخص EN

Aim.

Risk based screening for developmental dysplasia of the hip (DDH) with ultrasound is common.

However, risk factors vary from one country to the other since data are insufficient to give clear recommendations.

We aimed to evaluate the risk factors for developmental dysplasia of the hip (DDH).

Methods.

In this retrospective case-control study, the health records of all children, who were followed up between 2004 and 2014 at a well-child unit, were investigated for the diagnosis of DDH in Turkey.

Of 9758 children, 57 children were found to have abnormal ultrasonographic findings (according to Graf classification) and these constituted the case group.

As the control group, healthy 228 children who matched the case children in birth months were selected.

Two groups were compared for the risk factors.

Results.

A total of 19516 hips of 9758 children were examined for DDH.

97 hips of 57 children were found to have abnormal ultrasonographic findings.

When the two groups were compared, breech presentation, multiple pregnancy, and torticollis were identified as risk factors.

The female sex was also found to have a significantly high prevalence among the children in the case group.

Limited hip abduction, positive Ortolani, and Barlow signs were important clinical findings in the case group.

Conclusion.

According to our findings, breech presentation, female sex, torticollis, and multiple pregnancy were found to be the risk factors of this disorder.

Infants with these risk factors should be investigated carefully for DDH.
