A clicking hip in a newborn baby should never be ignored

Area of Science:

• Pediatric Orthopedics
• Neonatal Screening
• Developmental Dysplasia of the Hip

Background:

• Early detection of hip abnormalities in newborns is critical for preventing long-term complications.
• Minor hip signs like clicking or grating are often overlooked but may indicate underlying pathology.

Purpose of the Study:

• To evaluate the association between minor hip signs in newborns and the subsequent development of serious hip pathology.
• To determine the necessity of systematic follow-up for infants exhibiting minor hip signs.

Main Methods:

• A cohort of 7864 infants was examined within 48 hours of birth.
• Infants with minor hip signs (clicking or grating) were followed clinically and radiologically at 4 months.
• Comparison of hip pathology rates between infants with and without minor newborn hip signs.

Main Results:

• Infants with minor hip signs had a 39 times higher incidence of dislocated or dislocatable hips compared to normal infants.
• Of infants with minor signs, 5.5% (34/622) showed serious hip pathology at 4 months.
• Only 7/7196 infants with normal newborn exams required later orthopedic referral.

Conclusions:

• Clicking and grating hip signs in newborns are significant indicators of potential developmental dysplasia of the hip.
• Systematic follow-up, including radiological examination at 4-6 months, is recommended for infants with minor hip signs.
