Oolani test is positive when the examiner hears the ?

Ans. is 'a' i.e., Clunk of entry on abduction and flexion of hip Clinical tests for CDH/DDH In infancy two tests are used. Barlow's test This test is done within 2-3 days of bih. The test has two pas :? Pa 1 :- Infant is in supine position with hip and knee in 90deg of flexion, The hip is slowly adducted & pushed to dislocate the hip and one can hear a clunck of exit of femoral head out of the acetabulum. Pa 2 :- Now the hip is gentely abducted and pulled to reduce the hip. This will cause 'clunk' indicating reduction of hip. It is quite obvious that pa 1 can be done only dislocatable hip; but not in already dislocated hip as the head is already out of the acetabulum. Oolani's test This test is similar to 2nd pa of Barlow's test, i.e. slow abduction of hip in flexed position of hip & knee to reduce the hip.
