Ortolani test

Medical diagnostics

Hip-joint, front view.

Synonyms| Ortolani maneuver
Purpose| exam developmental dysplasia of the hip

The Ortolani test is part of the physical examination for developmental dysplasia of the hip, along with the Barlow maneuver.[1] Specifically, the Ortolani test is positive when a posterior dislocation of the hip is reducible with this maneuver. This is part of the standard infant exam performed preferably in early infancy.{{citation needed|date=April 2014} [Marino Ortolani]], who developed it in 1937.[2]

## Procedure

The Ortolani test is performed with the Barlow maneuver and inspection of the hip joint and legs. It relocates the dislocation of the hip joint that has just been elicited by the Barlow maneuver.[3]

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.[3]

## Interpretation

Right hip-joint from the front.

A positive sign is a distinctive 'clunk' which can be heard and felt as the femoral head relocates anteriorly into the acetabulum:.[4]

Studies show that Ortolani and Barlow are moderately sensitive (sensitivity 46%, 95% CI, 26%-67%) and highly specific (specificity 99.1%, 95% CI, 97.9%-99.6%) for the diagnosis of developmental dysplasia of the hip.[5]
