Causes And Risk Factors Linked To Avascular Necrosis

Avascular necrosis occurs when blood flow to a bone is cut off, resulting in the death of the affected bone tissue. Also known as osteonecrosis, bone infarction, and aseptic necrosis, this condition most often affects the hips, knees, shoulders, spine, and wrists. Some patients may develop avascular necrosis on both sides of the body. Typically, the only symptom is joint pain, and this may occur even while the patient is resting. If left untreated, avascular necrosis can cause the bone to collapse, resulting in arthritis and the need for joint replacement surgeries.
