"Osteonecrosis (plural: osteonecroses) is a generic term referring to the ischaemic death of the constituents of bone. It has a wide variety of causes and can affect nearly any bone in the body. Most sites of involvement have an eponym associated with osteonecrosis of that area (see list below), and these sites are discussed individually, as each site has unique clinical, aetiologic and prognostic features."
"Historically, the terms ischaemic and avascular necrosis were typically reserved for subchondral (epiphyseal) osteonecrosis, whereas bone infarct referred to medullary (metaphyseal) osteonecrosis. The term avascular necrosis (and also aseptic necrosis) is usually seen in older publications. Osteonecrosis is a more general and inclusive term, and is now preferably used 10; it is also important to note that necrosis is always avascular. However, often both osteonecrosis and avascular necrosis are often used interchangeably, which can lead to confusion 7."
