Ortolani’s click
A click felt when the
thigh is abducted in flexion, in congenital dislocation of the hip. It results from
the sliding of the femoral head over the
acetabular rim. A click can also be felt
when the head slips out of the acetabulum
on the opposite maneuver. Called
also Ortolani’s sign.
