Avascular necrosis (AVN) is a condition that occurs when the blood supply to a bone is interrupted and the bone tissue begins to die. It is also known as osteonecrosis, aseptic necrosis, or ischemic bone necrosis. It can affect any bone but is most common in the hip and shoulder. Early stage 3 avascular necrosis is a serious condition that can lead to severe pain, joint damage, and disability.
Symptoms of Early Stage 3 Avascular Necrosis
The symptoms of early stage 3 avascular necrosis may vary depending on the location of the affected bone. Common symptoms include pain, swelling, and stiffness in the affected area. Other symptoms may include a decrease in range of motion or difficulty walking.
Causes of Early Stage 3 Avascular Necrosis
The exact cause of early stage 3 avascular necrosis is often unknown, but the condition can be caused by an injury or trauma to the bone, use of certain medications, and other medical conditions. It is more common in individuals who have certain risk factors such as age, alcohol and tobacco use, and certain medical conditions.
Treatment of Early Stage 3 Avascular Necrosis
Treatment for early stage 3 avascular necrosis may include rest, physical therapy, medications, and surgery. Non-surgical treatments such as rest and physical therapy may be enough to reduce pain and improve joint function. Surgery may be necessary in more severe cases to prevent joint destruction and disability.
