A 2-week-old infant is noted to have asymmetric thigh folds and a clunk on abduction of the hip. The most likely diagnosis is:

• A Proximal femoral focal deficiency
• B Septic arthritis
• C Congenital knee dislocation
• D Developmental dysplasia of the hip ✓

Explanation

Asymmetric thigh folds, limited abduction, and an Ortolani clunk are classic signs of developmental dysplasia of the hip (DDH) in neonates. Septic arthritis presents with fever and swelling. Congenital knee dislocation and proximal femoral focal deficiency have different physical findings. DDH is the most likely diagnosis.
