Which test assesses the ability to reduce a hip dislocation in infants?

The Ortolani Sign is a clinical test specifically designed to assess the ability to reduce a hip dislocation in infants. It is part of the physical examination for developmental dysplasia of the hip (DDH). During the test, the examiner flexes the infant's knees and abducts the hips while applying gentle pressure to the greater trochanter. A palpable "clunk" indicates that a dislocated hip has been successfully reduced back into the acetabulum. This behavior of the hip is crucial for early detection and intervention, as untreated hip dislocations can lead to significant morbidity later in life.

In contrast, Barlow's Test also evaluates hip stability and identifies potential dislocation but focuses on dislocating the hip rather than reducing it. The Slocum Test assesses anterior cruciate ligament (ACL) stability in the knee and is not relevant to hip evaluations. The Noble Compression Test is used to assess for iliotibial band friction syndrome and also does not relate to hip dislocation or its reduction. Thus, the Ortolani Sign directly addresses the question about reducing a hip dislocation in infants.
