Evaluation of formalin preserved allogeneic bone graft as a grafting material

Formalin preserved allogeneic(FPA) bone graft was used in 18 patients with benign bone cavities, nine patients with malignant bone cavities, 12 patien ts with atrophic nonunion of fractures, seven with gap nonunion and 18 with comminuted fractures. The benign bone cavities were obliterated in 20 week s and malignant cavities in 24 weeks. Union was obtained in atrophic ununit ed fractures in 29 weeks, in gap nonunion in 40 weeks and in comminuted fra ctures in 27 weeks. FPA is a simple, inexpensive and easily available alter native to autologous bone and to deep frozen bone in filling bone defects a nd enhancing fracture union.
