Abstract
Aseptic necrosis of bone may result from a number of causesas
vascular disturbances, injuries, the action of chemicals, and the application
of radium in the treatment of malignant disease. The process of repair of the
damaged area differs with the causative agent and with the amount of
functional stimulation to which the part is subjected during the reparative
period. It also differs from that seen in cases of necrosis produced by
infection. Necrosis en masse produced by severe infection is nearly
always followed by a fibroblastic and fixed tissue phagocytic reaction which
usually results in complete absorption of the dead bone, if the area is small,
or in sequestration, if it is large. However, mild inflammatory reactions,
particularly when associated with embolic or thrombotic processes and due to
low grade micro-organisms, may sometimes result in necrosis which is followed
by simultaneous absorption of dead bone and incomplete, irregular replacement
by new bone (creeping substitution).
