Ortolani manoeuvre (or-toh-lah-ni mă-noo-ver) n. a test for congenital dislocation of the hip in which, with the baby lying supine and the pelvis steadied with one hand, the examiner attempts to relocate a dislocated hip by gently abducting the hip while simultaneously pushing upwards on the greater trochanter. If the hip is dislocated, it will relocate with a detectable and sometimes audible clunk. [ M. Ortolani (20th century), Italian orthopaedic surgeon]
