What are the two signs that evaluate for congenital hip dislocation in infants?

The two signs used to evaluate for congenital hip dislocation in infants are the Barlow maneuver and the Ortolani maneuver. These tests are specifically designed to detect hip dysplasia or dislocation by assessing the stability of the hip joint.

The Barlow maneuver involves gently pushing the thigh back while applying pressure on the knee to see if the hip can be dislocated. If the hip pops out of the socket, it indicates that the hip joint may not be stable.

The Ortolani maneuver, on the other hand, is performed by abducting the hip while applying upward pressure on the femur to relocate a dislocated hip. If a palpable "clunk" is felt, it suggests that the hip is being relocated into the socket.

Together, these two tests are critical in identifying and managing congenital hip dislocation early, allowing for appropriate interventions that can prevent long-term complications such as pain and impaired mobility. Other options mentioned are related to different areas of examination and are not relevant to assessing congenital hip dislocation.
