Avascular necrosis, or osteonecrosis, is a condition in which the bone tissue dies due to a lack of blood supply. This condition can occur in any bone but is most common in the hip, shoulder, and knee. People with avascular necrosis may experience pain, joint stiffness, and limited range of motion.
Diagnosis of Avascular Necrosis
A doctor may suspect avascular necrosis based on a patient's symptoms and a physical exam. Imaging tests, such as an X-ray, MRI, or CT scan, can help confirm the diagnosis.
Treatment of Avascular Necrosis
Treatment for avascular necrosis will depend on the severity of the condition. Early stages may be treated with medications, lifestyle modifications, and physical therapy. Surgery may be necessary for more severe cases.
Prevention of Avascular Necrosis
The best way to prevent avascular necrosis is to avoid risk factors, such as smoking, excessive alcohol consumption, and certain medications. It is also important to maintain an active lifestyle and eat a healthy diet.
