Interrelationship Between Newborn Developmental Dysplasia of the Hip and Fetal Malpresentations and Malposition in Labor: a Cross sectional Study

Interrelationship Between Newborn Developmental Dysplasia of the Hip and Fetal Malpresentations and Malposition in Labor: a Cross sectional Study
Background: Developmental Dysplasia of the Hip (DDH) is one of the most common congenital musculoskeletal problems in newborns. Its incidence varies in different populations and multiple risk factors have been reported
Objectives: To determine the prevalence of developmental dysplasia of the hip (DDH) in newborns who had malposition and malpresentation at the time of delivery and to identify the presence of any other risk factors.
Methods: A cross-sectional study was conducted on 507 Kurdish women who had fetal malpresentation and malposition during labor at the Maternity Teaching Hospital, Erbil city, Kurdistan Region. Ultrasound of the newborn’s pelvis was conducted within 14 days of delivery and the Graf ultrasound method was used to screen for DDH.
Results: The prevalence of DDH was 6.5 %. No significant associations were detected between the prevalence of DDH and the gestational age, parity, family history of DDH, mode of delivery, and amniotic fluid volume or any categories of mal-presentation.
Conclusions: The rate of DDH is considerably high among a sample of Kurdish ethnicity neonates. There are no relative risk factors for its development.
