What should I do about avascular necrosis?

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

What can I do to prevent or lessen the chance of avascular necrosis?

Options limited: Depends on the location and manner of fracture. Shoulder & hips at highest risk for avascular bone necrosis, so only real prevention is not getting injured to begin with. In some special cases you can take steps to reduce risk. Deep sea divers (due to the bends) and patients on high dose long term corticosteroids are more at risk. Talk to your dr. ...Read more

What exacting is avascular necrosis? I have it in my legs, knees.

Lack of blood supply: Avascular necrosis occurs when blood supply to an area of bone is cut off, for example your knee. Blood carries oxygen & nutrients to all parts of your body, including bone. Without blood supply that part of the bone "dies". This is a serious condition especially if it affects the femoral area of the hip. ...Read more

What is avascular necrosis?

Avascular necrosis: Bone is a living tissue that is constantly turning over; this involves tightly regulated systems of bone addition and subtraction. 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

Is avascular necrosis serious?

Yes: Avascular necrosis is bone death due to lack of blood supply. This can occur in joints where the blood supply can be easily disrupted by injury or disease. Joints such as the hip, knee, wrist, elbow or ankle. Some medications such as steroids can increase risk of this problem. Disease which have increased risk include diabetes, sickle cell disease, gout, atherosclerosis. ...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). Depending on the location and extent, treatment ranges from physical therapy and waiting, to some orthopedic surgery procedures. If you are still on steroids, you and your oncologist will have the risk/benefit ratio of stopping. ...Read more

Yes and no: Avclascular necrosis, ischemic bone necrosis, (avn) is a disease where there is cellular death (necrosis) of bone components due to interruption of the blood supply. When you have injection or used steroid rarely you will have side effect to the cortisone used what we call avn of the bone sometimes happen after few month to year from using the medications or injection.

I have avascular necrosis in both my talus will it ever heal without surgery?

Very small chance: The talus has a very delicate blood supply. About the only conservative treatment would be a bone stimulator, which could promote bone healing and activity. It is more likely, however, that surgery will be necessary. This usually consists of a fusion, whether it is an ankle fusion or pantalar fusion. ...Read more

Possibly but others: Although avascular necrosis can be related to corticosteroids it is important to know that there are other causes of avascular necrosis. There is a decrease in blood flow to the area involved. Although corticosteroids can be associated, it depends on dose and time and thus chemo steroids are less likely to be associated. Other causes: alcohol, joint injury and increased pressure ...Read more
