What is osteonecrosis?

Ostconecrosis literally means "death of bone" (osteo = bone, necrosis = death). This condition is often called avascular necrosis. It leads to tiny breaks, and often eventual collapse from within the bone. Osteonecrosis frequently appears in relation to another disease or conditions such as rheumatoid arthritis or alcoholism. The underlying problem of osteonecrosis is a decrease in the blood supply to the affected area. The most common areas affected are the hips, knees, and shoulders.
