Bone infarcts? I’ve heard of myocardial infarcts, I’ve heard of cerebral infarcts; but bone infarcts? What is an infarct?
Normally, blood carries oxygen and nutrients to cells. However, in some instances the flow of blood is obstructed and the tissue beyond the obstruction dies. In the case of a myocardial (or heart) infarct, blood flow to the heart muscle is blocked and the muscle tissue dies; a heart attack.
In the case of a cerebral infarct, the blood flow to the brain is obstructed; the result, a cerebral infarct or what is often known as a stroke.
If oxygen and nutrients can’t reach bone because of an obstruction, the bone dies. Bone infarcts can happen in lupus due to treatment with prednisone, blood clots from antiphospholipid syndrome (common in lupus) and high cholesterol; to name a few. Other names for more than one bone infarct: osteonecrosis or avascular necrosis.
Bone infarcts are usually found in or around the joints and long bones and can be quite painful. Tell your doctor about the pain, preferably a rheumatologist or a bone specialist, a orthopedist, or orthopedic surgeon
