Abstract

According to the 1993 definition of osteonecrosis by the Association Research Circulation Osseous (ARCO), bone is a type of mineralized tissue, and any disease that causes necrosis of bone tissue is called osteonecrosis. Common features include bone tissue degeneration, necrosis, and collapse caused by temporary or permanent loss of bone blood supply. Pathological changes often involve joints, leading to the collapse of the articular facet and resulting in disability. Osteonecrosis can occur in various body parts. Femoral head necrosis can be classified as traumatic or idiopathic. The author investigated necrosis of the femoral head in 30,080 normal people (>15 years old) from nine provinces and autonomous regions in China. The incidence of femoral head necrosis was 0.726% (1.02% in men and 0.51% in women). The results show non-traumatic osteonecrosis is a public health issue in China.
