Osteonecrosis

Osteonecrosis is a condition that occurs when blood supply to the bones in the joints is diminished. New bone is constantly replacing old bone in humans with healthy bones. The absence of blood in osteonecrosis causes the bone to break down quicker than the body can replace it. The bone begins to deteriorate and may shatter. Osteonecrosis can affect one or numerous bones. It most commonly affects the upper leg. Your upper arm, knees, shoulders, and ankles are other popular locations. Men and women of any age can have the condition, although it commonly hits in your thirties, forties, or fifties. You may not experience any symptoms at first. As the condition progresses, you will most likely have increasingly severe joint discomfort. You may find it difficult to bend or move the afflicted joint.
