Clinical pearls from this deck

• Two risk factors and a normal examination still means a scan. The examination is what you image around, not what you rely on.
• The newborn tests stop working at three months. After that, look at abduction and at the level of the knees.
• The socket is shaped by the head sitting in it. That is why the harness allows movement rather than preventing it.
• The worst outcome in this condition is caused by its treatment. That is why gentle is not a courtesy here, it is the technique.
• Ortolani puts it in. One letter is all it takes to stop confusing the two for good.
• Examine the hip in every child with knee pain. The hip refers pain to the knee, and the knee never refers pain to the hip.

This deck is open to everyone with no sign-in. Work through it once for recognition, then again a week later to test yourself.
