Which signs may indicate developmental dysplasia of the hip in infants?

• A. Thigh folds
• B. Laxity of the hip joint
• C. Both thigh folds and laxity
• D. None of the above

Answer: (C)

Understanding early indicators of developmental dysplasia of the hip in infants relies on noticing signs that point to instability at the hip joint. Two commonly observed signs are thigh folds and hip joint laxity. Asymmetric thigh folds occur when one leg shows deeper or uneven folds compared with the other. This reflects that the hip on that side may be malaligned or dislocated, causing the limb to sit differently and create uneven skin folds. Hip laxity means the hip joint is looser than normal, so it can be more easily displaced with handling or movement. This looseness signals instability in the joint, which can progress to dislocation if not addressed. If both signs are present, the likelihood of developmental dysplasia of the hip is higher, and it prompts earlier, targeted evaluation. This usually involves a careful physical exam—including Ortolani and Barlow-style maneuvers as appropriate—and imaging (often ultrasound) to confirm the diagnosis and guide management. While each sign can occur on its own, their combination strengthens the concern for DDH and the need for further assessment.
