What is Avascular Necrosis?
Bone tissue in the body can eventually die if cut off from a healthy blood supply, in a phenomenon known as Avascular Necrosis, also known as Osteonecrosis. Over time, Avascular Necrosis can cause many small cracks and breaks in the bone tissue that will eventually lead to a total collapse.
An injury such as a joint dislocation or fracture can lead to Avascular Necrosis due to interrupting the blood flow to the bone. Frequent alcohol consumption and taking high doses of steroid medication for long periods of time increase the risk of Avascular Necrosis.
Avascular Necrosis can occur in anyone but appears more often in patients between the ages of 30 and 50.
How is Avascular Necrosis diagnosed?
During a physical exam, a doctor will press around your joints, checking for tenderness. They might also move the joints through different positions to see if the range of motion is lessened. If they suspect you may have Avascular Necrosis, they may call for imaging tests.
