NCIt definition : When testing for congenital dislocation of the hip, this is the result obtained when
the examiner gently abducts the hip while pushing upward on the greater trochanter.
If the hip is dislocated, it will relocate with an audible clunk, which is a positive
result for this test.;
Alternative definition : NICHD: A physical examination performed on infants to screen for developmental dysplasia
of the hip that attempts to relocate a posteriorly displaced femoral head anteriorly
into the acetabulum.;
