Description[edit | edit source]

The instability of the hip may be assessed by the Ortolani and Barlow tests, which play a big role in the clinical screening for developmental dysplasia of the hip [1]. The Barlow Test is a physical examination performed on infants to screen for developmental dysplasia of the hip. Barlow’s test identifies posterior sublimations or dislocation. It is named after Dr. Thomas Geoffrey Barlow, who devised this test. It was clinically tested during 1957–1962 at Hope Hospital, Salford, Lancashire [2].

The Ortolani Test was described in 1936 by an Italian pediatrician Marino Ortolani; an outstanding pioneer in the early diagnosis and treatment of hip dysplasia. He describes it as a simple test that would establish a diagnosis of congenital dislocation of the hip in children one- year- old [3].
