Osteonecrosis (ON) is a degenerative manifestation of bone in which the cellular component dies following an interruption of the blood supply. \n<\/p>\n\n

Causes<\/h2>\n\n

Reduced blood supply can be caused by:<\/p>\n\n

  • Joint or bone trauma. An injury, such as a dislocated joint, can cause nearby blood vessels to break down. Cancer treatments involving radiation can also weaken bones and damage blood vessels.<\/li>
  • Fat deposits in blood vessels. Fat (lipids) can block small blood vessels. This can reduce blood flow to the bones.<\/li>
  • Some diseases. Sickle cell anemia and Gaucher disease can also reduce blood flow to the bones.<\/li><\/ul>\n\n

    Risk factors<\/h2>\n\n
    • Knee joint trauma<\/li>
    • Steroids<\/li>
    • Cushing’s disease<\/li>
    • alcohol abuse<\/li>
    • Connective tissue diseases, including systemic lupus erythematosus<\/li>
    • Osteomyelitis<\/li>
    • Human immunodeficiency virus infection<\/li>
    • Organ transplantation<\/li>
    • Hemoglobinopathies, including sickle cell disease<\/li>
    • Hyperlipidemia<\/li>
    • Gout<\/li>
    • Renal failure<\/li>
    • Pregnancy<\/li>
    • Radiation therapy<\/li><\/ul>\n\n
