Will Avascular Necrosis Spread?

Avascular necrosis cannot spread from one body part to the other. However, there are certain conditions, which cause avascular necrosis in numerous joints of the body. Avascular necrosis may affect numerous bones in certain disorders.

How fast does avascular necrosis progress?

AVN has four stages that can progress over a period of several months to more than a year. In Stage I, the hip is healthy; in Stage II, the patient experiences mild pain in direct proportion to the deterioration of the head of the femur (or ball of the hip joint).

What happens if avascular necrosis is left untreated?

Untreated, avascular necrosis worsens with time. Eventually, the bone can collapse. Avascular necrosis also causes bone to lose its smooth shape, potentially leading to severe arthritis.
