The authors have studied the ultrastructural modifications after one year of a homologous bone grafting stored for 8 days in nitrogen liquid at -196 degrees C. It was observed that the osteocytes showed nuclear and cytoplasmic degenerations; the empty lacunae showed precipitates of mineralized matrix. In comparison with a bone autografting a homologous bone grafting lost the ability of bone synthesis.
