What does a negative Barlow or Ortolani test indicate in an infant regarding hip development?

A negative Barlow or Ortolani test demonstrates that there is no dislocation or instability in the hip joints of the infant. The Barlow test assesses for the ability to dislocate the hip, while the Ortolani test checks for the ability to reduce a dislocated hip back into the socket. When both tests yield negative results, it suggests that the hip joints are properly positioned and stable, indicating normal hip development.

Normal findings in these tests are particularly essential in newborns and young infants. The purpose of these maneuvers is to identify developmental dysplasia of the hip (DDH) early in life. If these tests are negative, it typically means that there is a low likelihood of hip dysplasia and that the infant's hip development is progressing as expected. This can help reassure parents and guide further monitoring and care.

While other options may imply various actions or concerns, a negative result in these specific tests predominantly signifies that normal hip development is anticipated.
