AVN - Avascular Necrosis
What is Avascular Necrosis?
Avascular necrosis is the death of bone tissue due to a lack of blood supply.
Also called osteonecrosis, it can lead to tiny breaks in the bone and the bone's eventual collapse.
​

​
Causes
Reduced blood supply can be caused by:
-
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
