The answer

Hello, as you may know Avascular Hip Necrosis is the name given to the condition when bone tissue has died due to lack of blood supply. One of the most common reasons for this happening is where the bone is fractured or the joint becomes dislocated. It can also be associated with long term high dose steroid use and excessive long term alcohol consumption. These and other causes for Avascular Necrosis of the hip to occur can broadly be described as follows;

  • Joint or bone trauma. An injury, such as a dislocated joint, might damage nearby blood vessels. Cancer treatments involving radiation also can weaken bone and harm blood vessels.
  • Fatty deposits in blood vessels. The fat (lipids) can block small blood vessels, reducing the blood flow that feeds bones.
  • Certain diseases. Medical conditions, such as sickle cell anemia and Gaucher's disease, also can cause diminished blood flow to bone.

Unfortunately for about 25 percent of people with avascular necrosis, the cause of interrupted blood flow is unknown.

As you can see the possible causes are wide and varied which you may like to discuss with your specialist as to the particular cause of this in your case and best of luck with your treatment.
