Avascular necrosis – also known as osteonecrosis – is characterized by bone tissue death due to a temporary or permanent loss of blood supply to the bones. Avascular necrosis can lead to tiny breaks in the bone or eventual collapse of the bone altogether. Though this condition typically affects the end of long bones like the femur, common sites for avascular necrosis include the upper arm bone, knees, shoulders and ankles. Diagnosis of this disease can be obtained by orthopaedic doctors. Treatment centers on preventing future bone loss and depends on what bone damage an individual already has. Typical treatment includes medication, therapy and surgery.
