Quizplus · Accepted Answer

Asymmetric thigh and gluteal creases may indicate potential dislocation of the hip.Positive Ortolani's sign yields a "clunking" sensation and indicates a dislocated femoral head moving into the acetabulum.During a positive Barlow test,the examiner can feel the femoral head move out of the acetabulum.If the hip is dislocated,the knee on the affected side will be lower.
