Avascular necrosis

What is Avascular Necrosis?

Avascular necrosis is a condition that affects our bones. It happens when the blood supply to a bone is disrupted, causing the bone tissue to die. This can lead to pain, stiffness, and difficulty in moving the affected joint. Avascular necrosis commonly occurs in the hip, but it can also affect other joints like the knee, shoulder, and ankle.

Diagnosis of Avascular Necrosis

Diagnosing avascular necrosis involves a physical examination and medical imaging tests. During the examination, the doctor will ask about your symptoms and medical history. They may also perform tests to assess your range of motion and joint stability. Medical imaging tests, such as X-rays, MRI, or CT scans, are used to confirm the diagnosis and determine the extent of the bone damage.

Treatment for Avascular Necrosis

Treating avascular necrosis aims to relieve pain, improve joint function, and prevent further damage to the affected bone. Non-surgical treatments may include medications to reduce pain and inflammation, physical therapy to strengthen the muscles around the joint, and assistive devices like crutches or braces. In some cases, surgery may be necessary to remove damaged bone or replace the joint with an artificial one.

Preventive Measures for Avascular Necrosis

While avascular necrosis cannot always be prevented, there are some measures you can take to reduce the risk. Avoiding excessive alcohol consumption and quitting smoking can help maintain healthy blood flow to the bones. It is also important to protect your joints from injuries and to manage any underlying conditions, such as diabetes or high cholesterol, that may increase the risk of avascular necrosis. Regular exercise and maintaining a healthy weight can also contribute to overall bone health.
