DESCRIZIONE

Avascular Necrosis (AVN) is a disease resulting from temporary or permanent loss od blood supply. It frequently affects the femoral head and in this area, if left untreated, routinely evolves in premature joint destruction. In the USA, 5 to 10% of cases of hip osteoarthritis requiring total hip replacement are primarly caused by avascular necrosis. In 33 to 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, like the conservative treatment through the electomagnetic fields and shockwaves 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. Table of contents 1. Preface; 2. Physiopathology; 3.
