Avascular necrosis is defined as the localized death of cells in the bone due to lack of blood supply to it. It results in weakening or collapse of the bone.
It is also called osteonecrosis or ischemic bone necrosis and most commonly occurs in the hip. The other common sites include shoulders, knees and ankles.
Management & treating of underlying cause of avascular necrosis to minimize progression of disease
Joint-preservation operations: These procedures are done in early avascular necrosis of the hip to improve blood supply to the affected bone
Joint Replacement: Done in advanced stages where bones are collapsed and arthritis is evident
