The cost of house extensions can be cheaper than the cost of moving to a larger home and may even add more value to your home than their initial cost. However, there are significant costs involved, some of which may be budget busters if not anticipated.
Medical Definition of Necrosis. Necrosis: The death of living cells or tissues. Necrosis can be due, for example, to ischemia (lack of blood flow). From the Greek nekros (dead body).
[edit on Wikidata] Avascular necrosis (AVN), also called osteonecrosis, bone infarction, aseptic necrosis, and ischemic bone necrosis, is cellular death (necrosis) of bone components due to interruption of the blood supply. Without blood, the bone tissue dies and the bone collapses. If avascular necrosis involves the bones of a joint, it often leads to destruction of the joint articular surfaces. (see Osteochondritis dissecans).
