Abstract

Purpose

The aim of this study was to determine the prevalence of developmental dysplasia of the hip (DDH) in preterm infants with maternal risk factors.

Methods

A prospective review of the medical records and ultrasound (US) scans of all preterm infants at one tertiary-care children’s hospital was completed to identify all premature infants without any infantile risk factors at a particular time frame. We consecutively evaluated 421 babies (842 hips) who satisfied the criteria for inclusion. Hip US images were classified according to Graf.

Results

Overall, one hip was diagnosed as DDH (Graf type 2c). Female infants had significantly lower alpha angles (70.2 ± 6.6 and 71.4 ± 4.4 for females and males, respectively) (P = 0.033). There was no correlation between oligohydramnios and alpha and beta angles and hip sides (P = 0.345 and P = 0.789 for left and right hips, respectively). US examination of the infants revealed no differences between the alpha and beta angles of the hips and birth weight and age at gestation. Although it was statistically not significant, US evaluation of left hips among singletons demonstrated one immature hip (P = 0.864) and that of right hips demonstrated one immature hip for both singletons and twins (P = 0.904).

Conclusions

Prematurity with or without maternal risk factors does not have an effect on DDH.
