Detailed explanation-1: -Avascular necrosis is a disease that results from the temporary or permanent loss of blood supply to the bone. When blood supply is cut off, the bone tissue dies and the bone collapses. If avascular necrosis happens near a joint, the joint surface may collapse. This condition may happen in any bone.
Detailed explanation-2: -Osteonecrosis can be caused by disease or by severe trauma, such as a fracture or dislocation, that affects the blood supply to the bone. Osteonecrosis can also occur without trauma or disease. This is called idiopathic–meaning it occurs without any known cause.
Detailed explanation-3: -Avascular necrosis (osteonecrosis) is a serious condition that results in the death of bone tissue due to a lack of blood supply. While anyone can be affected, it is more common among individuals with certain medical conditions or who have experienced trauma in the area.
Detailed explanation-4: -The incidence rate of osteonecrosis was 4.7 cases/10000 person-years (95% CI, 4.6 to 4.7 cases). Among men, the incidence rate was 3.5 cases/10000 person-years (95% CI, 3.4 to 3.6 cases). Among women, it was 5.7 cases/10000 person-years (95% CI, 5.6 to 5.8 cases).
