Sample item

What is the preferred imaging test to screen infants at risk of developmental dysplasia of the hip before femoral head ossification?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Hip ultrasound

Hip ultrasound visualizes the immature femoral head and acetabulum and is useful for early assessment of developmental dysplasia.

Option by option

  • A. Hip ultrasound (correct)

    Correct: ultrasound is suited to the unossified infant hip.

  • B. CT scan of the pelvis

    CT exposes infants to radiation and is not first-line screening.

  • C. Plain chest radiograph

    Chest radiography does not image the hip.

  • D. Bone scintigraphy

    Bone scans are not routine screening for dysplasia.
