APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Perthes disease is a rare childhood condition that affects the hip. It occurs when the blood supply to the rounded head of the femur (thighbone) is temporarily disrupted. Without an adequate blood supply, the bone cells die, a process called avascular necrosis.

Detailed explanation-2: -Legg-Calve-Perthes disease (also known as Perthes disease) is a rare condition in which the ball-shaped head of the thighbone (femoral head) temporarily loses its blood supply. As a result, the head of the thighbone collapses, and the area becomes inflamed and irritated.

Detailed explanation-3: -Avascular necrosis of the femoral head is a type of osteonecrosis due to disruption of blood supply to the proximal femur. There are approximately 10000 to 20000 new cases reported each year in the United States alone. It can occur due to a variety of causes, either traumatic or atraumatic in origin.

Detailed explanation-4: -The top end of the thigh bone (femur) is shaped like a ball so that it can fit snugly into the hip socket. In the case of Perthes’ disease, this ball (femoral head) is softened and eventually damaged due to an inadequate blood supply to the bone cells.
