Osteonecrosis also called avascular necrosis, or bone infarction is a condition that results from an interruption of blood supply to the bone.
• The bone is a living tissue that requires blood, a lack of blood flow to the bone can lead to the death of bone tissue. If not treated, it can eventually cause the bone to collapse.
• The condition also causes the bone to lose its smooth shape, leading to severe arthritis.
• The most commonly affected joint is the hip bone but other common sites are the knees, shoulder, and ankles.
• Estimate has shown that as many as 20,000 people develop the condition annually.
• Anyone can be affected, but osteonecrosis is most prevalent in people between the ages of 20 and 50.
