The Ortolani test is part of the physical examination for developmental dysplasia of the hip, along with the Barlow maneuver.[1] Specifically, this tests for posterior dislocation of the hip.[citation needed] This is part of the standard infant exam performed preferably in early infancy.[citation needed]

The Ortolani test is named after Marino Ortolani, who developed it in 1937.[2]

Procedure[edit]

The Ortolani test is performed with the Barlow maneuver and inspection of the hip joint and legs.[citation needed] It relocates the dislocation of the hip joint that has just been elicited by the Barlow maneuver.[citation needed]

The Ortolani test is performed by an examiner first flexing the hips and knees of a supine infant to 90°, 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.

Interpretation[edit]

A positive sign is a distinctive 'clunk' which can be heard and felt as the femoral head relocates anteriorly into the acetabulum:[3]
