Insights
Preterm infants born breech have a similar risk of developmental dysplasia of the hip (DDH) as term infants. This finding is crucial for refining DDH screening guidelines for breech presentation.
Area of Science:
- Neonatal care
- Pediatric orthopedics
- Developmental pediatrics
Background:
- Developmental dysplasia of the hip (DDH) screening guidelines currently lack data on preterm breech infants.
- Understanding DDH risk in preterm breech infants is vital for evidence-based clinical practice.
Purpose of the Study:
- To determine if preterm infants born with breech presentation have a similar risk of DDH compared to term breech infants.
- To inform future DDH screening protocols.
Main Methods:
- Retrospective audit of 1144 neonates born in breech presentation.
- Comparison of DDH incidence across gestational age groups: 23-27, 28-31, 32-36, and ≥37 weeks.
- Logistic regression analysis to control for confounding factors.
Main Results:
- The incidence of DDH was comparable across all gestational age groups (ranging from 9.4% to 13.6%).
- Gestational age did not significantly influence the risk of DDH or the need for therapeutic intervention.
- Sixty infants required intervention for DDH.
Conclusions:
- Preterm infants born with breech presentation exhibit a similar incidence of DDH compared to their term counterparts.
- Current findings suggest that gestational age may not be a differentiating factor in DDH risk for breech infants.
- This study provides essential data for updating DDH screening guidelines.
Background:
Whether preterm infants born with breech presentation are at similar risk of developmental dysplasia of the hip (DDH) as the term breech infants is not known. The information will be vital for DDH screening guidelines.
Methods:
A retrospective audit of infants born in the breech position was performed to compare the incidence of DDH in the following gestational age groups: 23-27, 28-31, 32-36 and ≥37 weeks.
Results:
A total of 1144 neonates were included in the study. The incidence of DDH did not differ between the groups (11.6%, 9.4%, 13.6% and 11.5%, in 23-27, 28-31, 32-36 and ≥37 weeks, respectively, p=0.40). Sixty infants required intervention for DDH. Multiple logistic regression after correcting for potential confounders showed that gestational age group did not influence the risk of DDH, and requirement of therapy.
Conclusion:
Preterm infants born with breech presentation appear to have a similar incidence of DDH to term breech infants. .
