The loss of blood flow results in bone death, which is referred to as “avascular necrosis” or “ischemic necrosis” of the femoral head. Perthes disease is also referred to as Legg-Calvé-Perthes disease or Legg-Perthes disease.What kind of disease is Legg Calve Perthes disease?
Legg–Calvé–Perthes disease (LCPD), is a childhood hip disorder initiated by a disruption of blood flow to the head of the femur. Due to the lack of blood flow, the bone dies (osteonecrosis or avascular necrosis) and stops growing.How long does Perthes disease last without blood supply?
Without an adequate blood supply, the bone cells die, a process called avascular necrosis. Although the term "disease" is still used, Perthes is really a complex process of stages that can last several years.How often does Perthes disease occur in children?
Perthes' disease is one of the most common hip disorders in young children, occurring in roughly 5.5 of 100,000 children per year. The lifetime risk of a child developing the disease is about one per 1,200 individuals. Boys are affected about three to five times more often than girls.
