The Ortolani test or Ortolani maneuver is a physical examination for developmental dysplasia of the hip.[1]

It is performed by an examiner first flexing the hips and knees of a supine infant to 90 degrees, then with the examiner's index fingers placing anterior pressure on the greater trochanters, gently and smoothly abducting the infant's legs using the examiner's thumbs.

A positive sign is a distinctive 'clunk' which can be heard and felt as the femoral head relocates anteriorly into the acetabulum:[2]

Specifically, this tests for posterior dislocation of the hip.

This is part of the standard infant exam performed preferably in early infancy; it usually becomes negative after 2 months of age.

It is performed with the Barlow maneuver and inspection of the hip joint and legs.

It is named for Marino Ortolani, who developed it in 1937.[3]
