How can avascular necrosis cause hip pain?

ANSWER

Avascular necrosis (also called osteonecrosis) is a condition that happens when blood flow to the hip bone slows and the bone tissue dies. Although it can affect other bones, avascular necrosis most often happens in the hip. It can be caused by a hip fracture or dislocation, or from the long-term use of high-dose steroids (such as prednisone), among other causes.
