Question 1

can coffee cause avascular necrosis?

Accepted Answer

No: Although caffeine isn't good for bone density, regular consumption of coffee doesn't cause avascular necrosis.

Question 2

what could cause avascular necrosis of the hip?

Accepted Answer

Fall or trauma: Avascular necrosis is typically caused by a very hard traumatic blow to an area or repetitive trauma to an area that causes a lack of blood flow to the bone and therby creating the avascular necrosis.  You need to see your orthopedist.

Question 3

do steriods from chemo cause avascular necrosis?

Accepted Answer

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

Question 4

why does steroids cause avascular necrosis?

Accepted Answer

We are not sure: We are not sure but there is a linkage seen whether it may be more related ti the underlying problem for which the steroids  are given as treatment in the first place.

Question 5

could using steriods from chemo cause avascular necrosis?

Accepted Answer

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.

Question 6

can remicade (infliximab) cause or worsen avascular necrosis?

Accepted Answer

No: Nothing reported to the fda, or any case reports in literature that i could find.

Question 7

how does prednisone cause avascular necrosis?

Accepted Answer

Still unknown: Even though there is this very well-established connection between chronic Prednisone use and avascular necrosis, how this occurs remains unclear.

Numerous hypotheses abound. Some argue that increased lipids seen with steroids cause vessels to joints to clog, leading to oxygen starvation & bone death. A more popular view is that vessel (venous) walls undergo thickening, leading to poor blood flow.

Question 8

can avascular necrosis of the shoulders be caused by a work related strain?

Accepted Answer

No: Avascular necrosis can be associated with trauma, if the blood supply to the bone is interrupted by injury.  Most of the time, the cause is unknown.  Certain diseases such as sickle cell anemia or alcoholism have higher rates of avascular necrosis. It is not associated with strain or sprain type injuries. Steroid use is also a cause of avascular necrosis.

Question 9

why is the " corticosteroid administration " can cause " avascular necrosis" ?
i need the mechanism how does the " corticosteroid" work.

Accepted Answer

Not Known: While it is generally agreed that the key problem in avn is compromised blood flow to the bone, the mechanism by which corticosteroid use contributes to avn is not known.  It is important to remember that this is a rare and not a common problem in corticosteroid users.

Question 10

why do steroids cause avascular necrosis of the femur head?

Accepted Answer

Unknown: No one really knows for sure. However, it has been shown that steroids cause elevation of lipids. In rabbits, steroids cause collections of lipids called an embolism. The emboli caused avascular necrosis of the femoral heads in the studied rabbits.
