Developmental dysplasia of the hip: Beyond the screening. Physical exam is our pending subject.

Introduction: Developmental dysplasia of the hip is a common cause of disability among children. Early detection leads to better prognosis. There are some risk factors that increase the possibility of developing a dysplasia. But not every child with developmental dysplasia has them. This means that physical examination is still very useful to detect them. However, based on clinical findings, the amount of requested ultrasound seems higher than it would be necessary.
Methods: Retrospective cohort study of infants born in a single tertiary care centre. Babies in which hip ultrasound was performed were included. During the period of study, patients with diagnosis of developmental hip dysplasia were also included, as well as the amount of ultrasounds requested during this period, and their efficiency.
Results: Out of the 456 newborns included, 530 hip ultrasounds were performed. Just 3 of the total 12 dysplasias had risk factors. The others were diagnosed through clinical examination.
Conclusions: Screening protocols are useful to detect hip dysplasia but clinical examination is very important to detect those cases without risk factors. However, the number of tests is higher than expected according to the diagnosed dysplasias.
