        Avascular necrosis (AVN), also known as osteonecrosis, aseptic necrosis, or ischemic bone necrosis, is a condition that causes bone cells to die due to a lack of blood supply. Because of the irregularity of the joint surface, it frequently causes collapse of the joint surface and subsequent arthritis. Avascular necrosis is a condition that affects the ends (epiphysis) of long bones such as the femur, upper homers, and ankle joint bones. It usually develops as a result of a combination of factors such as metabolic, genetic, increased alcohol consumption, smoking, and other diseases.   An X-ray is commonly used to determine the source of joint pain. MRI, on the other hand, is the most sensitive method for diagnosing avascular necrosis in its early stages. MRI detects chemical changes in the bone marrow and shows avascular necrosis in its early stages, unlike X-rays, bone scans, and computed/computerized tomography (CT) scans. Nonsurgical treatment opt...

    Bone cells die due to a lack of blood supply in a condition known as avascular necrosis (AVN). It is also known as osteonecrosis, aseptic necrosis, or ischemic bone necrosis. Because of the irregular joint surface, it frequently results in the collapse of the joint surface and subsequent arthritis. The ends (epiphysis) of long bones such as the femur, upper humerus, and ankle joint bones are affected by avascular necrosis. It usually occurs as a result of a combination of factors, such as metabolic, genetic, increased alcohol consumption, smoking, and other diseases.      An X-ray is commonly used to determine the source of joint pain. However, the most sensitive method for diagnosing avascular necrosis in its early stages is magnetic resonance imaging (MRI). MRI detects chemical changes in the bone marrow and shows avascular necrosis in its early stages, unlike X-rays, bone scans, and computed/computerized tomography (CT) scans. The global avascular nec...
