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. [1] It can occur due to a variety of causes, either traumatic or atraumatic in origin.

Aseptic necrosis is a bone condition that results from poor blood supply to an area of bone, causing localized bone death. This is a serious condition because the dead areas of bone do not function normally, are weakened, and can collapse. Aseptic necrosis is also referred to as avascular necrosis or osteonecrosis.
Definition. Aseptic necrosis of the hip is the death of bone tissue in the head of the thigh bone (femur) due to poor blood supply. Legg-Calvé-Perthes disease is a type of aseptic necrosis in children. It affects the growth plate at the upper end of the thigh bone.
Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, it can lead to tiny breaks in the bone and cause the bone to collapse. The process usually takes months to years. A broken bone or dislocated joint can stop the blood flow to a section of bone.
Osteonecrosis of the hip, commonly known as avascular necrosis (AVN) of the hip, is the death of the femoral head as a result of the vascular disruption. AVN of the hip results in pain around the hip which is insidious in onset. The cause is generally multifactorial and more commonly seen in males compared to females.
thigh boneThe femoral head (femur head or head of the femur) is the highest part of the thigh bone (femur). It is supported by the femoral neck. Upper extremity of right femur viewed from behind and above.
Collapse of the femoral head is the most significant pathogenic complication arising from osteonecrosis of the femoral head. It is related to the disruption of the maintenance of cartilage and bone, and results in an impaired function of the vascular component.
