Avascular necrosis is a localized death of bone as a result of local injury (trauma), drug side effects, or disease. This is a serious condition because the dead areas of bone do not function normally, are weakened, and can collapse..
Correspondingly, what happens if avascular necrosis is left untreated?
If left untreated, the disease progresses, and the bone may develop a crack whereby the bone can get compressed (collapse) together (similar to compressing a snowball). If this occurs at the end of the bone, it leads to an irregular joint surface, arthritic pain and loss of function of the affected areas.
Likewise, how long can you live with avascular necrosis? Prognosis for Avascular Necrosis More than half the people with this condition need surgery within 3 years of diagnosis. If a bone collapse in one of your joints, you're more likely to have it happen in another.
