What does this maneuver assess?

Allis sign-allis sign is used to detect unequal leg length, which could indicate congenital hip dislocation and should be assessed at every office visit until one year of age. the nurse is positioned at the infants feet. with the infant supine, the nurse flexes the infants knees, keeping the femurs aligned, and compares the height of the knees. an uneven height indicates unequal leg length. tibial torsion is a curving of the tibias. genu valgum (knock knees) is found typically after the age of four and identified when the child walks. genu varum (bowlegs) is identified in infants before they learn to walk.
