Ortolani’s Test

Ortolani Test

What is the "Ortolani’s Test" used for?

  •  Developmental dysplasia of the hip in newborn.

How to perform the "Ortolani’s Test"?

  • It must be carried out on a relaxed child, preferably after feeding.
  • Flex the knees and encircle them with the hands so that the thumbs lie along the medial sides of the thighs and the fingers over the trochanters.
  • Flex the hips to a right angle and, starting from a position where the thumbs are touching, abduct the hips smoothly and gently.

What is the positive result?

  • If a hip is dislocated, as full abduction is approached the femoral head will be felt slipping into the acetabulum. An audible click may accompany the displacement.
  • Note that restriction of abduction may be pathological, and represent an irreducible dislocation.
  • A positive Ortolani test is indicative of neonatal instability of the hip (NIH), and is usually an indication for splintage.

Test Accuracy

  • Sensitivity: 66 %
  • Specificity: 95 %
