What are the Ortolani and Barlow maneuvers?
What are the Ortolani and Barlow maneuvers?
The Ortolani maneuver identifies a dislocated hip that can be reduced. The infant is positioned in the same manner as for the Barlow maneuver, in a supine position with the hip flexed to 90º. From an adducted position, the hip is gently abducted while lifting or pushing the femoral trochanter anteriorly.
What does Ortolani test for?
dislocation of an unstable hip by gently adducting flexed hip while pushing posteriorly in line of shaft of femur; – Ortolani test identifies dislocated hip that can reduced in early weeks of life; – a positive test requires active treatment (see treatment in newborns);
How do you do Ortolani and Barlow test?
A posterior force is applied through the femur as the thigh is gently adducted by 10-20 °. Mild pressure is then placed on the knee while directing the force posteriorly. The Barlow Test is considered positive if the hip can be popped out of the socket with this maneuver. The dislocation will be palpable.
How do you perform the Barlow and Ortolani test?
How is Barlow test done?
The Barlow Maneuver is done by guiding the hips into mild adduction and applying a slight forward pressure with the thumb. If the hip is unstable, the femoral head will slip over the posterior rim of the acetabulum, again producing a palpable sensation of subluxation or dislocation.
When is the Barlow test done?
Barlow’s Test If the hip is unstable, the femoral head will slip out of the acetabulum, producing the palpable sensation of the hip dislocating. If the hip is dislocatable, then Barlow’s test is positive.
Why do we do the Barlow test?
Thomas Geoffrey Barlow (September 25, 1915 – May 25, 1975), an English orthopedic surgeon, who devised this test….

What is the difference between Ortolani and Barlow provocative manoeuvres?
Barlow provocative manoeuvres attempt to identify a dislocatable hip adduction of the flexed hip with gentle posterior force while Ortolani manoeuvres attempt to relocate a dislocated hip by abduction of the flexed hip with gentle anterior force 1,2.
When do Ortolani and Barlow tests stop being positive?
The Ortolani and the Barlow tests are no longer positive from week eight to twelve . It has been recommended that the Barlow test should be done by gently adducting the hip while palpating for the head falling out the back of the acetabulum and that no posterior-directed force be applied.
Are the Barlow and Ortolani tests for neonatal hip instability reliable?
Reliability of the Barlow and Ortolani tests for neonatal hip instability Video recording for critical analysis and feedback is a useful technique in this situation. Overall, the results suggest that testing for neonatal hip instability was inadequate.
What is the sensitivity of the otolani and Barlow test?
The sensitivity of clinical examination (Ortolani and Barlow) by trained examiner was 0.667 (95 % CI: 0.284, 1.000) while its specificity was 0.958 (95%CI: 0.880, 1.000). However, the specificity and sensitivity could not be calculated in the second group because there was no positive case was detected (Table II).
