Abstract
SUMMARY Bone grafts were used in the past to provide for internal fixation as well as for osteogenesis. At pr¬esent, with the great advances in metallurgy, which have given the means to provide rigidity in places where bone is deficient, grafts aremo,stly used to provide for ost eogenesis. A bone graft does not function as a living trans¬p l an t , but only as a sui table framework wi thin which new bone C8l1 be laid down from the host. Grafts are now commonly used to fill a cavity, to bridge the gap between an ununi ted fracture, or to fuse a joint. Free grafts, unlike skin grafts are unable to ac¬quire a blood supply sufficiently fast to prevent nec¬rosis of most of the bone cells. With fresh autografts, some of the superficial osteocytes and the endosteal and periosteal osteoblastes may survive, but there contri¬bution to the healing process is small.
