Aseptic necrosis of the femoral head (ANFH) may result from:
traumatic injuries of the joint;
complications of coronavirus infection;
long-term use of glucocorticoid hormones;
alcohol abuse.
Necrosis of the hip joint most often occurs in children aged 3 to 15 years. Although the exact causes of the disease in children are unknown, doctors are inclined to the presence of genetic defects. Also, circulatory disorders in the joint are often associated with past viral infections. Trauma in the form of a dislocation of the joint can also cause aseptic necrosis in childhood.
Adult patients in most cases experience aseptic necrosis as a complication of another disease. In the past 2 years, this has been caused by COVID-19 infection.
Diseases such as sickle cell anemia and Gaucher disease can also reduce blood flow to the joints.
Violation of blood flow with the subsequent development of the pathology of the femoral head can be triggered by AIDS or systemic lupus erythematosus.
