Bone grafting using allografts or autografts may be used to fill cavities after removal of large amounts of bone that might result in instability,or to fill bony defects and to promote the union of fractures at the time of open reduction.Banked bone is available in many shapes of cortical and cancellous tissue.The American Association of Tissue Banks (AATB)accredits and periodically inspects bone-banking programs to ensure that specific standards are followed in the retrieval,processing,storage,and distribution of bone grafts.Bone graft that is sealed in a sterile labeled envelope from a tissue transplant company and stored in a vacuum-sealed freezer,monitored with an alarm,would be considered a(n):
