AbstractDevelopmental dysplasia of the hip (DDH) is a common hip disorder in infants. Ultrasonographic screening is considered the most reliable method for early detection of DDH in newborn infants. This study aimed to determine the incidence of DDH at King Abdulaziz University Hospital. From January 2017 to December 2018, this retrospective study analyzed the data of 8031 infants who underwent an early clinical examination of the hips. At the initial evaluation, 212 infants referred to the ultrasound department had risk factors for DDH and/or clinical instability. Different well-known risk factors of DDH have been identified including breech position, skeletal deformities, positive family history, hip side, sex and clicky hip. The findings revealed an incidence rate of 93 cases of DDH among 8031 infants (11.58 per 1000) births. Among the infants diagnosed with DDH, 55 were females (59.14 %), and 38 were males (40.86%). The results of the current study revealed that 45% of infants with DDH exhibited bilateral involvement. Moreover, results showed that the IIa hip joint was more prevalent in female than in male newborns, but without any significant difference. The incidence rate of DDH in this study was 11.58 per 1000 live births, and it was more prevalent among female than male newborns. Ultrasonography (US) should be used as a complementary imaging modality for clinical examination of DDH. Infants with breech presentation, clicky hip, and skeletal deformity should be scanned by US. Further prospective studies are recommended.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
