Avascular necrosis of the femoral head

Avascular necrosis is a disease resulting from temporary or permanent loss of blood supply. It frequently affects the femoral head and in this area, if left untreated, routinely evolves into premature joint destruction. In the United States, 5%-10% of cases of hip osteoarthritis requiring total hip replacement are primarily caused by avascular necrosis. In 33%-72% of patients, the disease is bilateral. The peak incidence is between 30 and 60 years of age and the social costs of this pathology are remarkable. There is therefore increasing interest in hip joint-preserving techniques, such as conservative treatment through electromagnetic fields and shock waves, as well as joint-preserving surgical techniques. This volume intends to present a complete overview of the current knowledge of avascular necrosis, including therapeutic options. Book jacket.
