What is Osteonecrosis

Osteonecrosis, also known as avascular necrosis, is a condition that occurs when there is a temporary or permanent loss of blood supply to a bone, resulting in bone cell death. This condition commonly affects the hip, knee, shoulder, and ankle joints, but can occur in other bones as well.

Osteonecrosis can be caused by various factors, including trauma, excessive alcohol consumption, long-term use of corticosteroid medications, certain medical conditions (such as sickle cell disease or lupus), and radiation therapy. The lack of blood supply to the bone leads to the death of bone cells, causing the affected bone to weaken and potentially collapse.

Symptoms of osteonecrosis may include joint pain, stiffness, limited range of motion, and difficulty bearing weight on the affected joint. The progression of the condition varies from person to person, and early diagnosis is crucial to prevent further damage.

Treatment options for osteonecrosis depend on the stage and location of the affected bone. Non-surgical approaches, such as pain management, physical therapy, and lifestyle modifications, may be recommended in the early stages. In advanced cases, surgical interventions like core decompression, bone grafting, or joint replacement may be necessary to alleviate pain and restore joint function.

If you suspect you may have osteonecrosis or are experiencing joint pain, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
