Ossification of decalcified and nondecalcified homologous bone grafts

This two-year study examined the process of reossification and survival of decalcified and nondecalcified bone grafts implanted under the scalp tissue of 15 rabbits. Both radiologic and histologic examination showed that the nondecalcified fresh-frozen bone specimens became totally viable and recalcified while largely retaining their initial size. The decalcified bones, however, were totally absorbed within a period of four months. Possible reasons for failure of the decalcified bone to reossify are discussed.
