Marino Ortolani: "Does That Baby's Hip Go Click?"

Area of Science:

• Orthopedics
• Pediatrics
• Developmental Biology

Background:

• Hip dysplasia is a common congenital condition affecting infants.
• Early diagnosis and treatment are crucial for preventing long-term complications.
• Marino Ortolani was a key figure in advancing the understanding and management of hip dysplasia.

Observation:

• Ortolani observed an audible and palpable "click" during hip abduction-adduction in infants with congenital hip pre-dislocation.
• This "click" was correlated with radiographic evidence of hip joint instability.
• The finding suggested a non-invasive method for early detection of hip dysplasia.

Findings:

• The Ortolani maneuver, characterized by the "click" sign, proved effective for diagnosing congenital hip pre-dislocation.
• Anatomical dissections of fetal and infant hip specimens confirmed that hip dysplasia can develop in utero.
• Ortolani's extensive collection of specimens provides clear evidence of hip dysplasia's etiopathology.

Implications:

• Ortolani's test is now a standard diagnostic procedure in pediatric and orthopedic practices worldwide.
• The findings underscore the importance of early detection for timely intervention in hip dysplasia.
• The anatomical collection at the University of Padua serves as an invaluable resource for studying hip dysplasia pathogenesis.
