Paediatric hip--ultrasound screening for developmental dysplasia of the hip: a review

Area of Science:

• Pediatrics
• Radiology
• Orthopedics

Background:

• Developmental dysplasia of the hip (DDH) is a condition requiring early detection.
• Ultrasound (US) screening is a common method for identifying DDH in infants.
• Concerns exist regarding the accuracy and potential overtreatment associated with US screening for DDH.

Purpose of the Study:

• To evaluate the effectiveness of ultrasound screening for developmental dysplasia of the hip (DDH).
• To determine the clinical significance of sonographic findings in neonatal hip screening.
• To assess the impact of overtreatment on resources and patient morbidity.

Main Methods:

• Literature review from January 1996 to December 2000.
• Analysis of 4 years of hip ultrasound screening data from 11,326 infants (aged 3 days to 4 months).
• Tracking of abnormal sonographic findings, treatment rates, and complications such as avascular necrosis.

Main Results:

• Abnormal sonographic hip findings were present in 4.7% of infants.
• 3.36% of infants had type IIa hip findings, with 65% normalizing on follow-up.
• Treatment was initiated in 2.5% of infants, with a 1.06% rate of avascular necrosis.

Conclusions:

• Routine generalized ultrasound screening of neonatal hips is supported.
• Optimizing screening approaches can limit false positives and reduce overtreatment.
• Effective screening balances early detection with minimizing unnecessary interventions and associated risks.
