Which condition does the Barlow's Test help to evaluate in infants?

Barlow's Test is specifically designed to assess hip stability in infants, particularly in the context of developmental dysplasia of the hip (DDH). This clinical examination maneuver involves gently adducting and pushing the infant's thigh posteriorly while stabilizing the pelvis. A positive Barlow's Test is indicated by the sensation or sound of the hip dislocating, which may suggest that the hip joint is unstable and potentially dislocatable.

In evaluating infants, early detection of hip instability is crucial, as timely intervention can prevent long-term complications such as hip osteoarthritis and avascular necrosis. Consequently, this test is a vital part of the physical examination for newborns and infants, particularly those who may be at higher risk for hip dysplasia due to factors like family history or in breech presentation during delivery.

The other conditions listed are unrelated to the evaluation performed by Barlow's Test. Leg length discrepancies involve measuring the lengths of the limbs and aren't addressed by this specific hip evaluation. Meniscal injuries and knee ligament integrity are concerns associated with the knee joint and would usually involve different tests more relevant to older children or adults rather than infants.
