In order to deliver the cells that are responsible there needs to be adequate blood flow. If the blood flow is disrupted significantly, the affected areas can undergo avascular necrosis (avn). Avn can lead to collapse of the area and arthritis if it occurs near joints. ...Read more

What should I do about avascular necrosis?

AVN: More information needed. In some bones (humeral + femoral head) if diagnosed before collapse and arthritis begins, there may be some value to core decompression. Some centers have shown decreased progression of collapse with free vascular fibula grafting (hip). No consensus regarding treatment before collapse. Once collapse occurs, some sort of resurfacing/replacement required to manage pain. ...Read more

Is there any alternative for curing avascular necrosis(avn)?

No: If avascular necrosis (avn) has occurred, then part of the bone is dead (necrosis) and there is no cure. There are many causes from lupus to sickle cell disease to corticosteroids to alcohol abuse. The key is to prevent further avn by addressing the cause: treatment of alcoholism, reducing load (obesity) on the damaged bone, reducing the need for steroids, etc. ...Read more

My brother was diagnosed with avascular necrosis. Any tips or suggestions for him?

See an MD: Avascular necrosis is the death of a joint due to disturbance of the blood supply. By far the most common is the hip joint and it mostly occurs as a side effect of long term, high dose steroid but also due to trauma to the joint. This is a serious problem, with significant joint pain and malfunction. Your brother has probably seen an orthopedic surgeon who can advise him about options. ...Read more

Could using steriods from chemo cause avascular necrosis?

Yes: This is a known complication of taking steroids, especially if you had to take prolonged courses during your chemo regimen (for acute lymphoblastic leukemia, for example).
