Bone transplantation and tissue engineering, part III: allografts, bone grafting and bone banking in the twentieth century.

During the 20th century, allograft implantation waned in popularity as a clinical activity. Reports appeared in the literature describing several small series of patients in whom bone was obtained from amputation specimens or recently deceased individuals. The concept of bone banking became a reality during and after World War II when the National Naval Tissue Bank was established in Bethesda and a number of small banks sprang up in hospitals throughout the world. Small fragments, either of cortical or medullary bone, from these banks were used heterotopically to augment spinal fusions, to implant into cyst cavities, or to serve as a scaffolding for repair of non- or delayed union of fractures of the long bones.
