Summary: Fifty infants with soft-tissue hip "clicks" persisting after age 3 months were prospectively studied by using ultrasound. All children demonstrated a stable hip examination by Barlow and Ortolani maneuvers; however, a click was palpated with abduction and adduction of the hip. Static ultrasonography demonstrated an average [alpha] angle of 63[degrees] in uninvolved hips and 62[degrees] in the clicking hips. All hips had >50% femoral-head coverage by the acetabulum. Dynamic ultrasound examination was normal in all cases. The soft-tissue clicks were not related to instability in this series of 50 infants.
