Aims: To identify the association between potential risk factors with developmental dysplasia of the
hip in neonates.
Study Design: A cross-sectional study.
Place and Duration of the Study: Laboratory of Lifestyle, Division of Health Sciences and
Engineering, Campus Celaya Salvatierra, University of Guanajuato Mexico, between June 2014 and
February 2015.
Methodology: We include 100 newborns, 36 male and 64 females with age between 4 and 28 days
old. Data on birth weight, family history of hip dysplasia, obstetric presentation, mode of delivery,
swaddling was obtained. The diagnosis of hip dysplasia hip ultrasonography with Graf technique was
confirmed. For association Chi squared and p value, for the effect was calculated Odds Ratio and
confidence intervals at 95%.
Results: It was found that obstetric presentation and swaddling were associated with developmental
dysplasia of the hip (p <0.05) with OR of 5.32 and 4.91 respectively, and the association was
confounded by area of residence with OR adjusted 2.94.
Conclusion: It was conclude that the most important risk factors for developmental dysplasia of the
hip in this population were obstetric presentation and excessive swaddling.
