Avascular Necrosis

Avascular Necrosis (AVN), also known as osteonecrosis, is a condition in which the blood supply to a bone is disrupted, leading to the death of bone tissue. This can result in the collapse of the affected bone and may eventually lead to joint degeneration. In the field of orthopedics, Avascular Necrosis commonly affects weight-bearing joints, such as the hip and knee, though it can also occur in other joints. Commonly affecting joints like the hip and knee, AVN may result from trauma, prolonged steroid use, or certain medical conditions. Symptoms include joint pain and limited mobility. Diagnosis involves imaging tests such as X-rays and MRI. Treatment varies from conservative measures like pain management to surgical interventions like core decompression or joint replacement. Staging helps determine the severity of AVN. Physical therapy is crucial for rehabilitation, aiming to maintain joint function. Prognosis depends on early detection and appropriate intervention, with outcomes ranging from symptom relief to joint replacement. Orthopedic specialists play a vital role in diagnosis and management.
