What is the term for the death of a bone?
Osteo necrosis literally means bone death in Latin (“osteo” = bone and “necrosis” = death). While many people do not think of bone as being alive, bones have their own blood supply and are constantly in the process of “remodeling” – old bone is breaking down while new bone is forming. Osteonecrosis occurs when the blood supply to a bone is interrupted. While this can occur anywhere on a bone, it occurs most frequently at the ends of bones, where the blood supply is most at risk. The bone most commonly affected is the femur, the large bone in the upper leg that runs from the knee to the hip. Osteonecrosis is sometimes also referred to as avascular (literally, “without blood supply”) necrosis or ischemic (“inadequate blood”) necrosis.
