Thank You Alabama

I am thanking each state that recognizes Avascular Necrosis- Osteonecrosis as it’s a rare condition that can be very debilitating

Avascular necrosis occurs when blood flow to a bone is interrupted or reduced. Reduced blood supply can be caused by:

Joint or bone trauma. An injury, such as a dislocated joint, might damage nearby blood vessels. Cancer treatments involving radiation also can weaken bone and harm blood vessels.
Fatty deposits in blood vessels. The fat (lipids) can block small blood vessels, reducing the blood flow that feeds bones.
Certain diseases. Medical conditions, such as sickle cell anemia and Gaucher’s disease, also can cause diminished blood flow to bone.
For about 25 percent of people with avascular necrosis, the cause of interrupted blood flow is unknown.

Risk factors
Risk factors for developing avascular necrosis include:

Trauma. Injuries, such as hip dislocation or fracture, can damage nearby blood vessels and reduce blood flow to bones.
Steroid use. Use of high-dose corticosteroids, such as prednisone, is a common cause of avascular necrosis. The reason is unknown, but one hypothesis is that corticosteroids can increase lipid levels in your blood, reducing blood flow.
Excessive alcohol use. Consuming several alcoholic drinks a day for several years also can cause fatty deposits to form in your blood vessels.
Bisphosphonate use. Long-term use of medications to increase bone density might contribute to developing osteonecrosis of the jaw. This rare complication has occurred in some people treated with high doses of these medications for cancers, such as multiple myeloma and metastatic breast cancer.
Certain medical treatments. Radiation therapy for cancer can weaken bone. Organ transplantation, especially kidney transplant, also is associated with avascular necrosis.
Medical conditions associated with avascular necrosis include:

Pancreatitis
Diabetes
Gaucher’s disease
HIV/AIDS
Systemic lupus erythematosus
Sickle cell anemia,factor v , Mthfr and other clot disorders
